Tungsten and tungsten alloy materials have become the key raw material for making armor piercing projectile in China.
Because of their high melting point, high hardness, high temperature strength, low coefficient of thermal expansion, high thermal conductivity and strong corrosion resistance.
With the development of China's manufacturing industry and smelting industry, the level of material research has reached a high standard in china. In recent years, nanotechnology and submicron technology have been popular in the material industry, and researchers have begun to explore the use of nanotechnology to fabricate tungsten core armor piercing projectile.
The conventional tungsten core armor piercing projectile is made of W - Ni - Fe high gravity alloy, the alloy combines W metal with high density, high strength and excellent matrix plasticity. Therefore, it has a series of excellent physical, chemical and mechanical properties, and is the key material of tungsten core armor piercing projectile.
The maximum tensile strength of fine grain tungsten alloy is 1700 MPa, it is about 30% higher than the traditional tungsten alloy, its dynamic mechanical performance was significantly improved after grain refinement of tungsten alloy, The fine grain tungsten alloy is used as a "self sharpening effect" in kinetic energy armor piercing projectile, so as to achieve stronger penetration effect.
Our tungsten armor piercing projectile has been developed into the third generation of fin stabilized unshell armor piercing projectile, one of the world's most powerful tungsten core armour piercing shells, and only the German DM63 tungsten core projectile is comparable. Nanotechnology will come into use, penetration will be further enhanced.
