Tungsten copper military shaped charge liner is part of armor-piercing projectile which plays an important role in action. Commonly used shaped charge liner is taper angle form. Generally, cone angle is ranging from 120 to 160 degrees.
Armor-piercing projectile rely on kinetic energy of the projectile to penetrate armor and destroy the target. Armor-piercing projectile are high velocity, long shooting distance and high precision of shooting, is the main ammunition of tank guns and the anti-tank guns. It also used in naval gun, coastal gun , anti-aircraft artillery and airborne cannon and used for mutilating tanks, self-propelled guns, armored vehicles, ships, aircraft, etc.
The theory of tungsten copper military shaped charge liner is called cavity effect .When the armor-piercing projectile detonates, the high temperature and high pressure instantaniously melting shaped charge ,then forming high temperature and speed metal jet which can sear even burnthrough the armored steel. So it is show that armor-piercing projectile take effective action by the cavity effect rather than rely on the kinetic energy.
Armor-piercing projectile’s armor ability is different when adopting different material of shaped charge. Copper used as material for shaped charge liner with low melting point and good ductility, however the density of copper is low and easily deformation, so it commonly mixed with tungsten to improve the density, which increase the armor ability of tungsten copper military shaped charge liner.
