Fine-grain tungsten alloy is a kind of material make from nano-powder, and prepared by fast sintering method. Its microstructure feature is average size of tungsten crystal much less than traditional tungsten alloy. Fine-grain tungsten alloy can be used to produce series of new types of tungsten alloy bullet core, such as armor-piercing after-effect bullet core. Its elongation is between bullet core material of armor-piercing cartridge and bullet core material of fragile cartridge. The bullet core made from this material can penetrate armor with certain thickness, so it has better armor-piercing performance than fragile cartridge. And different with normal armor-piercing cartridge, the bullet made from this material will be broken into many pieces to form some after-effect. This material can used for new type of tungsten alloy armor-piercing explosive incendiary cartridge to destroy the oil tank with armor or coming missile. Therefore, it’s a kind of new tungsten alloy with promising future.
