Shapes for Tungsten Fishing Jigs

Fishing sinker is a special type of tackle used to add weight to a line or lure. Anglers attach a sinker to draw bait down to depths where fish tend to congregate. Because the exact depth can vary by species, location and conditions, fishing enthusiasts often use a variety of sinkers to add different amounts of weight. The fishing sinkers were traditionally made of lead. However, lead is harmful to an enormous variety of wildlife, and lead fishing sinkers and other lead tackle contribute significantly to the risk.

The bell fishing sinker features a bell-shaped design with a swiveling hook fastened to the top. These fishing sinkers cast well in the wind, making them a favorite for shore anglers. The rounded profile of the fishing sinkers also reduces its chance of snagging. For boat anglers, bell fishing sinkers are often used on a three-way rig. This rig is designed to get baits deep without needing any extra equipment, like downriggers. The rig consists of a three-way swivel with one eye for the main line. The next loop holds a drop line with a bell sinker at its end. Finally, the last loop holds a leader and a lure or a live bait rig. The rig is effective when bounced along the bottom or lowered to a desired depth and trolled in open water.

The split shot is a small ball of lead with a slit cut into one side. To use this type of sinker, simply wrap the slit in the ball around your line and clamp down on the metal to secure it to the line. Some split shots feature small handles on the opposite side of the opening, allowing them to be removed and reused. A clam shot is a variation of a split shot. It maintains a groove for holding line and is an oval shape, making it more snag resistant. Despite their popularity, split shots pose some serious health and environmental risks, according to the U.S.

Geological Survey. Loons and other wildlife often swallow abandoned split shots, and then suffer illness or death due to the lead content. When large numbers of these sinkers are abandoned, they may increase the lead content in a body of water, which may eventually affect the drinking water for area residents.

How to Place Fishing Sinkers to the Line

If you use light bait such as a worm or an insect, you will find that your hook will float at the top of the water and it is difficult to attract any fish. A popular method of getting your hook to submerge further in the water is to use fishing sinkers. These small metal balls are easily placed on the line and 
increase your chances of catching a fish. So it is critical to place a suitable fishing sinker onto your fishing rigs, it is so easy that you can do it yourself if you have the necessary things, such as fishing line, scissors and sinkers and sometimes you need a snap swivel.

First remove your hook from the fishing line. You will not be able to place your fishing sinkers without a free end of fishing line to utilize. Use a pair of scissors to trim the hook off your line.

Run a line through one of your fishing sinkers. Most style of sinkers have a hole running through the middle of them. This is for securing it to the line. Thread the fishing line through the hole until several inches worth of line are fed out the opposite end of the sinker.

Then wrap the line around the fishing sinker and tie a knot. Make the knot stable, so the fishing sinker does not slide up and down the line. Also, estimate where your hook will be and how much slack you need to retie it to the line. Your fishing sinkers should be close to the hook but does not need to be directly above it.
Then, create individual knots if you determined that you need to use more than one fishing sinker on your fishing line because you want to lower your bait. While it may be easier to simply slide a few sinkers on the line and tie a knot, it may break the line. Repeat the above steps for each individual fishing sinker you use.
Finally, replace the hook that you have removed from the line once you have placed the fishing sinkers securely on your fishing line.

Tungsten Fishing Sinkers Composition

There are many different types of tungsten fishing sinkers and a variety of shapes and sizes that run from the basic to the bizarre. Split shot fishing sinkers, rubber core fishing sinkers, bell fishing sinkers, pyramid fishing sinkers, bank fishing sinkers, walking fishing sinkers, bullet fishing sinkers, egg fishing sinkers, dollar fishing sinkers, ball fishing sinkers, banana fishing sinkers and one or two eye fishing sinkers. And the pyramid fishing sinkers, bank fishing sinkers, dollar fishing sinkers, ball fishing sinkers, banana fishing sinkers and one or two eye sinkers are the most commonly used sinkers for saltwater fishing. 
Many environmentalists has been well studied the effect of lead shotgun shot on the environment and it was first reported in the late 1800s that large die-offs due to lead poisoning and continued through the next century, eventually the 1991 Federal ban on the use of lead shot in hunting turned up. However, the impact of lead fishing tackle has not been as well studied, but the poisoning is greatly touch everyone, because it’s everyone’s oblige to protect the environment from poisoned. So, more and more people call to adopt non-toxic materials like tungsten to be the materials for the tungsten fishing sinkers. As a result, tungsten with the environment friendly and easily machined properties praise highly between the fishing sinkers area.
  
Tungsten fishing sinkers are weight used in conjunction with a fishing lure or hook to increase its rate of sink, anchoring ability, and casting distance. Fishing sinkers have two-fold function, first getting the bait rig where you want but should keep it there. 
Different tungsten fishing sinkers have different weights. According to different uses or places they are used, it may be as small as 1/32 of an ounce for applications in shallow water, and even smaller for fly-fishing applications, or as large as several pounds or considerably more for deep sea fishing. Then according 

to different anglers, the concentration of shape and weight is 
different too. For example, for pier fishing, where distance is less important than structure and location, the weight of the sinker is more important than its overall shape. Other factors come into play for shoreline fishing, of course the angler's needs become more specialized.

Advantages of Tungsten Fishing Beads

A major advantage of having tungsten fishing beads incorporated into your favorite fly patterns is that they provide an element of flash to fly patterns by reflecting sunlight that has penetrated the water's surface.
A trout's diet naturally consists of approximately 90 percent aquatic insects so anything that you can do to your favorite nymph pattern to help get the trout's attention will pay big dividends. When tungsten fishing beads nymph anglers need to understand how fast a fly is going to sink. Experimenting with leader lengths and different sizes and types of beads will be needed to understand how fast the flies will sink. Using the countdown method after the cast will accurately let the fly angler know what level of the water column he or she is fishing.
In most cases when presenting flies to fishing holding in deep holes the smaller more aggressive fish will strike the fly closer to the surface. Getting the fly down deep and rolling it along the bottom will improve your chances of hooking the real lunker in the hole. 

Tungsten Nail Sinkers

Nowadays, a popular approach to weighting down soft plastics is the advent of small tungsten nail sinkers to add small amounts of weight internally to soft plastic lures.
Tungsten nail sinkers are thin and nail-like weights insert into soft-plastic baits, like jerk baits, sticks or finesse worms. Tungsten nail sinkers can be used to balance rigged jerk bait for a natural-looking fall. Another option is tail-weighting finesse worms for a tail-first, fall that can trigger hits from shy, following fish.
Tungsten nail sinkers are perfect for adding a small amount of weight to your soft plastic lures. An adjustment in weight can make the difference when conditions on the water change or you want to modify your bait's action. Easily clipped down with standard line clippers, tungsten nail sinkers are an ace-up-your-sleeve. The ability to make quick changes helps you stay one step ahead.
Each active tungsten nail sinker comes with three factors: a sharp tip to penetrate any section of the soft plastic lure, a narrow shank profile to minimize damage to the soft plastic lure and a set of conical barbs along the length of the shank to securely fasten the tungsten nail sinkers into the body of your soft plastic lure.

Nuclear Radiation Shielding


Nuclear radiation can be broadly classified into three categories. These three categories are labeled with the first three letters of the Greek alphabet: ά (alpha), β (beta) and γ (gamma). Alpha radiation consists of a stream of fast-moving helium nuclei (two protons and two neutrons). As such, an alpha particle is relatively heavy and carries two positive electrical charges. Beta radiation consists of fast-moving electrons or positron (an antimatter electron). A beta particle is much lighter than an alpha, and carries one unit of charge. Gamma radiation consists of photons, which are without mass and carry no charge. X-rays are also photons, but carry less energy than gammas. Some materials absorb beta rays. You can measure this absorption by fixing beta source and a radiation monitor so their positions do not change.
Damage of nuclear radiation
It can damage cells and the DNA inside them through its ionizing effect. This effect happens when a high-energy carrying particle or photon removes an electron within an atom’s nucleus from its orbit, thereby changing the properties of the atom. If enough ionization occurs DNA, cell and tissue damage result. Radioactive materials can enters the body through breathing, skin wounds and gastrointestinal absorption, causing inside radiation and outside the radiation can penetrate distance are absorbed into the body, make the person were external radiation, damage. Such as fatigue, dizziness insomnia, and skin redness, ulcers, hemorrhage, hair loss, leukemia, vomiting, diarrhea, etc. What's worse ,it can be distortion, hereditary disease incidence, affect the health of several generations. Generally speaking, the more body accept radiation energy, the more serious the radiation sickness symptoms and the greater the risk that the cancer and birth defects.

Process of Vacuum Metallization

Man in everyday life surrounds practical and aesthetically looking objects. It depends on things which possesses and uses not only him to be functional, but he fulfilled his expectations also in order to their appearances. Unfortunately not always given object was been possible to be obtained from materials which possess decorative properties. During the development of material engineering came into being the surface engineering, that includes all scientific and technical aspects of production, investigation and applying the superficial layers, which possess better than basic proprieties, mainly anticorrosive, anti-fatigue, anti-abrasive and decorative.

In last years the progress of science in the field of plastic materials permits on more and more different their use. Materials these are light, plastic and what follows it they are easy processed and formed as well as they are corrosion proof. Expensive in production metals were replaced by plastics, which in aim of assimilation to them are covered with the coat simulating the given metal.

Among methods of production of superficial layers, only three of them are suitable to use to cover the plastic materials. Developing process of vacuums metallization deserves on special attention.
During the vacuum metallization one can observe three phases of the process of coating manufacturing:
a) metal evaporation, it means the process of changing the state of a metal (from solid, through liquid into gas one),
b) diffusion of a metal vapor from the source of evaporation to the coating product or the wall of a vacuum chamber,
c) condensing of a metal vapor on the product surface and creating the continuous metal layer.

The process of vacuum metallization must be conducted in separate rooms. Also the particular departments should be isolated. On the other hand the process of metallization could be conducted using next equipment:
a) equipment for vacuum generation and it maintaining (and also it improving),
b) proper vacuum chambers for metallizing,
c) measuring apparatus for controlling the vacuum, the thickness of a metal layer and for investigation its features (e.g. resistance).

The process of vacuum metallization includes following operations and activities:
a) cleaning (in emulsified bathes or in dissolvents),
b) drying and placing products on the plating racks,
c) ground lacquering and surface tightening and second drying,
d) metallization,
e) painting with proper lacquer and drying,
f) quality control.

Tungsten Construction Parts for Plasma Technique

Applications which might gain more importance in the future are construction material for the tungsten alloyplasma technique in magneto hydrodynamic power generation (W and W-Cu) and target plates in fusion reactors (W, W-La2O3).
Recent plasma technique and theoretical and numerical studies show that tungsten may be the best, if not the only, material to withstand the extraordinary operating conditions in a nuclear fusion reactor diverter. The diverter, being that part of the vacuum vessel where the tungsten alloy plasma technique particles interact with the first wall, and where a large fraction of the fusion heat is removed, consists of water-cooled copper heat-exchanger element covered with a plasma facing armor. The tungsten alloy plasma techniqueparticles (electrons, protons, and α-particles) are directed by the magnetic field toward the diverter target plates, where they are neutralized and pumped. The convective heat flux reaches 20 MW.m-2 and the attendant 

surface temperature more than 3000. Therefore, a suitable armor material must have a high thermal conductivity (in order to transfer high heat fluxes), low thermal expansion coefficient and low Young’s modulus (in order to keep thermal stresses low), and a high melting point and low sputtering yield (in order to keep erosion low). Although tungsten does not have as high a thermal conductivity and as low a Young’s modulus as carbon-carbon composite materials, which are foreseen for the sections of the diverter with the highest heat flux, many experts believe that, in the long run, reasonable lifetimes will only be achieved by tungsten diverter plates, which have the lowest erosion rates of all materials in sections of the diverter with relatively low plasma temperature but high particle density.

For the technical realization of low-pressure plasma processes, one requires equipment with the following components:

Vacuum system (pump, vessel)
Energy supply
Gas supply
Measurement and control components for the reproducible adjustment of the process parameter
Due to the necessity of a vacuum system in most cases, batch operation method is the easiest solution.

The processes can be flexibly and complexly configured, in order to change the mode of action of the tungsten alloy plasma technique through variation of the process parameters (pressure, gas flow, gas composition, power) and can attain different effects in one process step. So that, i.e. without great expenditure a secondary cleaning can be carried out and immediately thereafter a corrosion protection layer becomes deposited, without having to aerate in between.

Tungsten Heavy Metal Microelectronic

Tungsten alloy microelectronics technology is developed in the late 20th century; it is a series of special technology such as the system circuit design, device physics, process technology, material preparation, automatic testing and packaging, assembly semiconductor technology, integrated circuit technology and so on. Tungsten heavy alloy microelectronic technology refers to design and manufacture and use the small electronic components and circuits. Tungsten alloy microelectronic is developed based on integrated circuit technology. 

A chemical etchant (and a method for forming the etchant) is disclosed for removing thin films of titanium-tungsten alloy microelectronic chip fabrication. The tungsten heavy alloy microelectronic removed is preferably 10% Ti and 90% W, which is layered onto a substrate under chromium and copper seed layers for electrode position of C4 solder bumps. Tungsten heavy alloy microelectronic products are widely used in computers and other machines.

In the application of tungsten heavy alloy microelectronic the Ti--W etchant should not attack aluminum, chromium, copper, or lead-tin solders, and should dissolve Ti--W rapidly. The invention achieves this with a mixture of 30% by weight hydrogen peroxide and water, to which is added EDTA and potassium sulfate.Tungsten heavy alloy microelectronic products vary in side and shape.

Microelectronic products have a lot of radiation which is very harmful to people’s body. Tungsten alloy microelectronic has high radiation absorption, this property determines as the first choice of material to make microelectronic products. That is one of the reasons why the tungsten alloy microelectronic products are very popular nowadays. Tungsten heavy alloy microelectronic also has the advantage of non-toxic and environmental friendly, tungsten alloy microelectronic can be reused and recycling.

The society advocate sustainable development, tungsten alloy is the perfect material to produce tungsten heavy alloy microelectronic products. The property of high temperature resistance is another reason for manufacturers to choose tungsten alloy as the material to produce tungsten heavy alloy 

microelectronic products. When the tungsten heavy alloy microelectronic products are used, they produce a lot of heat, many of the products made by other materials can not exist. We can provide all kinds of tungsten alloy microelectronic products according to your requirements.

Tungsten Alloy Armor-piercing


Nowadays, tungsten heavy alloy is progressively adopted since the raw substance to create components of army products, which include bullet, armor and shells, shrapnel head, grenade, hunting gun, bullet warheads, bulletproof vehicles, tank panzers, cannons, firearms, etc. A principal use for tungsten heavy alloy is in kinetic vitality penetrators, in which they are in instant rivalry with depleted uranium (DU).

Tungsten is a naturally occurring metal. Tungsten can be used in pure form or mixed with other metals to make alloys. Tungsten alloy tend to be strong, flexible, and resistant to wear. 

Tungsten and its alloys are used in a variety of commercial products including light bulb filaments, x-ray tubes, welding electrodes, grinding wheels, ceramic pigments, and fire retardants.

Numerous countries have used tungsten and various tungsten alloy munitions for a number of years because of its high density and resulting penetrating power for armor piercing rounds. Are there tungsten alloys in the Army's "green bullet"? The "green bullet" is a common term for the lead-free, small arms ammunition developed by the Army in an effort to provide soldiers with 

ammunition that is environmentally friendly. Military Tungsten alloy are not used in the "green" or lead-free bullet. "Green" bullets typically contain tungsten that is mixed together with either nylon or tin. Tungsten alloys, on the other hand, contain other metals, such as nickel, cobalt, iron, or copper, which are heated to high temperature that allows the materials to bond together. While the "green" bullet has been used in training operations at a limited number of Army installations, it has not been used on the battlefield.

More than 90 million rounds of the "green" training ammunition has been used in the United States, since its introduction. It relies on a blend of tungsten and nylon, or tungsten and tin. That gives the bullets the same density and firing properties as the original, but without using lead. Tungsten was considered non-toxic. Tungsten alloys are dense heavy metal composite materials used primarily in military applications.

Cleaning sterling silver jewelry

Caring for silver plated jewelry is similar to sterling silver jewelry. To remove tarnish from silver plated jewelry uses the same recommend cleaning techniques for cleaning sterling silver. The only major difference is reducing the amount of polish used as over exposure can inadvertently remove the silver plated.
Unlike sterling silver, silver plated jewelry will eventually wear in due time. Proper cleaning, maintenance, and storage are critical for extending its life usage. Some silver plated jewelry will last longer than others depending on the thickness of its layer.

Use polishing cloths. They are not abrasive and it will remove tarnish without a lot of effort. You can also try a tarnish removing paste found in jewelry stores, but be careful. Some products can be highly abrasive and would remove the plating after each polishing.

Care Tips for Sterling Silver Jewelry

When clean silver, you need to be very careful not to break the chain as silver is extremely pliable. Just like gold, silver is a very soft metal. You can scratch it just by rubbing it too vigorously. Also, never use a tissue, paper or tissues have wood fibers which can cause tiny scratches on the surface of your Sterling Silver jewelry. If you don’t regularly clean your silver pieces, the dirt residue can also scratch the surface as well.


All sterling silver will eventually oxidize and tarnish unless it has been finished with a protective layer. The good new is if it does tarnish, you can still restore it luster with proper polishing. The easiest way to clean silver is with a clean soft cloth. You can also prevent silver from tarnishing by just storing it away after each usage. Even a simple Zip-lock bag will be adequate, to keep all the air and light from tarnishing the Silver.
When cleaning sterling silver jewelry, we recommend you use soft 100% cotton clothing or even a flannel cloth. For hard to reach areas, you can use a soft bristle brush.
Chlorine and even vinegar can damage your silver jewelry, so don’t forget to take off your fine sterling silver jewelry when swimming.
