Tungsten Alloy Shot

Tungsten Alloy Shot

Tungsten alloy shot is used as the shot for shotgun hunting shells. The pellets spread upon leaving the barrel, and the power of the burning charge is divided among the pellets, which means that the energy of any one ball of shot is fairly low. In a hunting context, the product makes shotguns useful primarily for hunting birds and other small games.

Tungsten Alloy Shot Properties:

High density, great hardness and resistance to high temperature make tungsten to be one of the most sought -after material for shotgun pellets in hunting history . Density of tungsten alloy shot is about 18g/cm3, which is comparable only to gold ,platinum, or bismuth. To understand how the density factors of tungsten heavy alloy into performance, let us look at two spheres about the same size of tungsten alloy shot, a golf ball and a ping -pong ball. The golf ball is far denser and will fly farther and hit harder. Now reducing that size  down to two single, getting the picture. Tungsten alloy will fly farther, hit harder and penetrate deeper, which means more birds ,farther our ,with fewer cripples. Another unique property of tungsten alloy is that it is non-toxic and environmentally friendly. Therefore, it is safe for people to handle and work. It is our leading products, Chinatungsten can provide tungsten alloy shot as your requirements.

Swaging Rod For Armor Piercing

Tungsten Heavy Alloy Swaging Rod Grades under Transient High Heat Loads

Transient high heat loads simulations by using the electron beam facility have been performed on two tungsten heavy alloy swaging rod grades at several power loads with a pulse duration of 5 ms. The cracking patterns of the two tungsten heavy alloy swaging rod grades are quite similar. All cracks occurred along the grain boundary and located across the loaded area. The cracks can be distinguished with two levels, major cracks with larger crack width but lower crack density and microcracks with smaller crack width but higher crack density. The higher the deformation level of tungsten heavy alloy swaging rod and heat loading power density, the smaller the major crack density will be, but there is no obvious difference in the microcracks pattern. No melting occurred for both tungsten heavy alloy swaging rod grades after transient heat loading at power density of 0.88 GW m−2.

 
Tungsten alloy armor piercing projectile which is made of tungsten heavy alloy swaging rod comprising a high density penetrator core with a tapered front end and a multi-part outer case in partial contact with the core. This kind of tungsten alloy armor piercing projectile is made from tungsten heavy alloy swaging rod and will not penetrate because the multi-part jointed case is not as strong as a single-piece, monolithic case. Also, since the hard core is loose and not bonded to the case, then the core can not provide additional structural support. In addition, the tungsten alloy armor piercing projectile does not have the ability to either explosively damage the target after penetration, or take data from an instrumentation package during or after penetration.
Tungsten alloy armor piercing projectile comprising an axial core, a continuous strip of metallic glass wound about said core, and bonding means for joining the adjacent laminated surfaces. Tungsten heavy alloy swaging rod describes an outer case with a hole at its tip. This "hollow-point" design results in radial expansion of the jacket into "petals" as the tungsten alloy armor piercing projectile travels through the target. Such "flowering" of the case upon impact severely limits the depth of penetration into hardened targets.

Tungsten alloy armor piercing projectile comprising a heavy metal core and a segmented sabot with both right-handed and left-handed threads that separates from the core after exiting the gun's nozzle. This tungsten alloy armor piercing projectile will not penetrate deeply because the nose end is made of a brittle heavy metal alloy, rather than high-strength steel. Also, this tungsten alloy armor piercing projectile requires the use of a discarding sabot carrier.
Tungsten alloy armor piercing projectile with a speculating core comprising an elongated arrow style tungsten alloy armor piercing projectile with a core surrounded by a body, where the hardness of the core is greater than twice the hardness of the body. The outer case is made out of tungsten heavy alloy swaging rod. The brittle behavior of these alloys will prevent this tungsten alloy armor piercing projectile from achieving deep penetration in hardened targets, when compared to cases made of high-strength and high-toughness steel alloys.Tungsten heavy alloy swaging rod is our leader products. We can provide different sizes of tungsten heavy alloy swaging rod according as your requirements. 

Tungsten PET Shields

What is PET?
Brachytherapy Positron emission tomography (PET) is one of the nuclear medicine techniques available for diagnosis. Whilst X-rays provide information on the structure of the body, PET shows the chemical function of a particular organism. PET involves the injection of FDG (a glucose-based radionuclide) from a shielded syringe into the patient. As the FDG travels through the patient’s body it emits gamma radiation which is detected by a gamma camera, from which the chemical activity within cells and organs can be seen. Any abnormal chemical activity may be a sign that tumors are present. PET scans are frequently used to detect cancerous tumors and diseasesof the brain and coronary arteries.

Vidhwansak Anti Material Rifle and Tungsten Alloy Military

Vidhwansak (Sanskrit:"The Destroyer") is an Indian multi-caliber anti-materiel rifle (AMR) or large-caliber sniper rifle manufactured by Ordnance Factory, Tiruchirapalli. It can be used in the anti-materiel role for destroying enemy bunkers, lightly armoured vehicles, radar systems, communication equipment, parked aircraft, fuel storage facilities, etc. It is also effective in long range sniping, counter sniping and ordnance disposal (shooting explosive ordnance from a safe distance) roles.

Denel was earlier contracted to supply various weapon systems for the Indian Armed Forces, including Anti-materiel rifles and Self-propelled howitzers. However, following allegations that it had paid kickbacks to secure a deal for anti-material rifles, Denel was black-listed by the government.

Then, Ordnance Factory Tiruchirapalli (OFT), in association with the Defence Research and Development Organisation (DRDO), began developing an indigenous version of the Denel NTW-20 AMR to fill the need. The development of Vidhwansak was completed in November 2005. After all-terrain and all-weather trials, the user trials began in March 2006.

Production began in February 2007. After trials, the Border Security Force order 100 Vidhwansaks for use in the border areas. These were supplied by October 2008. The rifle has also been offered to the Indian Army and the National Security Guards.

Some reports suggest that the Vidhwansak is a reverse-engineered version of the NTW-20, of which Denel had supplied some units for trials. In any case, the Vidhwansak is comparable to the NTW-20 in terms of caliber, size and performance. The Vidhwansak, which costs Rs 10 lakh (USD 20,000) is much cheaper than comparable foreign alternatives such as the Denel NTW-20 AMR, which costs Rs 23 lakhs (USD 45,000). It also supports multiple calibers and fires 12.7mm, 14.5mm and 20mm rounds compared to dual calibers supported by the NTW-20. 

Features

Vidhwansak is a manually operated, rotating bolt action rifle. The barrel along with the receiver recoil inside the chassis frame against a damping system. The rifle is fed from a detachable box magazine, that is inserted from the left side. The rifle can be quickly disassembled and carried in two man-portable packs, each weighting about 12 - 15 kg.

The rifle has an effective range of 1800 m (1300 m for the 20 mm version), while shots can be achieved even up to 2000 m. The rifle is magazine fed, and reloaded through manual bolt action.

A muzzle brake is fitted on the end of the barrel which absorbs an estimated 50%-60% of recoil. This is further supplemented by a buffered slide in the receiver.

Vidhwansak is equipped with an 8X magnification, long eye relief telescopic sight with Parallax adjustment.

Military Tungsten Alloy

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.
