Tungsten Kinetic Energy Penetrator

What is Tungsten Kinetic Energy Penetrator?

A tungsten kinetic energy penetrator (also known as a KE weapon) is a type of ammunition that, like a bullet, does not contain explosives and uses kinetic energy to penetrate the target.
The term can apply to any type of armor-piercing shot but typically refers to a modern type of armor piercing weapon, the armor-piercing fin-stabilized discarding sabot (APFSDS), a type of long-rod penetrator (LRP), and not to small arms bullets.
The 'Fin' round travels at around 975 m/s (3200 ft/s), resulting in the generation of three and a half tones of force when it comes in contact with a weighted and/or fixed object. Energy, and therefore speed, inevitably decreases during flight, however it is still very deadly at ranges up to six kilometers.
The opposite technique to tungsten kinetic energy penetrator uses chemical energy penetrators. There are two types of these shells in use: high explosive anti-tank (HEAT) and high explosive squash head (HESH). They have been widely used against armor in the past and still have a role but are less effective against modern composite armor such as Chobham as used on main battle tanks today.

The principle of the tungsten kinetic energy penetrator is that it uses its kinetic energy, which is a function of mass and velocity, to force its way through armor. The modern KE weapon maximizes KE and minimizes the area over which it is delivered by:

being fired with a very high muzzle velocity concentrating the force in a small impact area while still retaining a relatively large mass maximizing the mass of whatever (albeit small) volume is occupied by the projectile—that is, using the densest metals practical, which is one of the reasons depleted uranium is often used. Tungsten kinetic energy penetrator has led to the current designs that resemble a long metal arrow. Concentration of force into a smaller area was attained by replacing the single metal (usually steel) shot with a composite shot using two metals, a heavy core (based on tungsten) inside a lighter metal outer shell. These designs were known as Armour Piercing Composite Rigid (APCR). On impact, the core had a much more concentrated effect than plain metal shot of the same weight and size. To maximize the amount of kinetic energy released on the target, the penetrator must be made of a dense material, such as tungsten carbide or depleted uranium (DU) alloy (Staballoy).  The hardness of the penetrator is of less importance, but is still a factor as abrasion is a major component of the penetrator defeat mechanism.A common misconception is that, during impact, fractures along these bands cause the tip of the penetrator to continuously shed material, maintaining the tip's conical shape, whereas other materials such as unjacketed tungsten tend to deform into a less effective rounded profile, an effect called "mushrooming". Actually, the formation of adiabatic shear bands means that the sides of the "mushroom" tend to break away earlier, leading to a smaller head on impact, though it will still be significantly "mushroomed". Tests have shown that the hole bored by a DU projectile is of a narrower diameter than for a similar tungsten projectile.That is one of the reasons why tungsten kinetic energy penetrator is better than the DU tungsten kinetic energy penetrator is. Tungsten alloy can be used as the component in the tungsten kinetic energy penetrator, and Chinatungsten Online can provide the tungsten kinetic energy penetrator.
