Tungsten alloy rod armour-piercing bullet is characterized by its slender body and small diameter. At present, the length-diameter ratio can reach about 30, and there is still a trend of development towards a larger length-diameter ratio. For example, the length-diameter ratio of the high-density alloy cartridge with rigid sleeves can reach 40, or even more than 60. The initial velocity of the projectile is 1500 ~ 2000m/s.
Tungsten alloy rod armour-piercing bullet is mainly made of tungsten alloy, which has high speed and kinetic energy. Tungsten alloy has high melting point, high strength and excellent performance, so that the projectile can adapt to higher launch overload and greater flight speed, which has become the best material to make the projectile.
