Penetrators Making Materials - Tungsten Alloy

Armor Piercing is one of the most common shells, hardness of the material is based on the shape of the shells, together with the kinetic energy of the firing transmission, when in contact with the surface of a hard target penetration failure to achieve the effect. Power depends on the kinetic energy penetrator bombs hit the target when, and physical properties of the material itself shells. Bore projectile was launched in the role after the drug resistance and accelerated collide only by gravity, in order to make the projectile hit the target when there is still a greater speed, armor-piercing must be used in the design tends to reduce the resistance of shape.

High density tungsten alloy is a class-based tungsten (tungsten mass fraction is usually 8O% ~ 97%), and added Ni, Fe, Mn, Co, Cu, Mo, Cr and other elements of the alloy, the density of up to 16 .5 ~ 19.0g / cm3. High density tungsten alloy not only density, but also has a series of excellent properties such as high strength, high hardness, ductility, good machining properties, thermal expansion coefficient, thermal conductivity, anti-oxidation and anti-corrosion can be good solderability and good. These properties make it excellent in the field of cutting-edge technology, military and civilian industry has been widely used, for example, as rod kinetic energy penetrator bomb core material, the counterweight components, inertial element ray shielding materials.

With main battle tanks, armored ships and a variety of increasingly strengthening military fortifications on the armor-piercing performance higher and higher requirements. High density tungsten alloy rod kinetic energy penetrators, not only has good armor-piercing power, and compared with depleted uranium alloy penetrators with non-toxic, non-radioactive contamination, etc., are the main countries in the world penetrator material and equipment, as well as the future development of the main projectile direction.
