Description

technical field

[0001] The invention relates to a tungsten heavy alloy for armor-piercing bullet cores and a preparation method thereof, belonging to the tungsten-based alloy category. Background technique

[0002] Tungsten heavy alloy is a material with high density, high strength, high ductility and minimal chemical activity. Using this tungsten heavy alloy to manufacture kinetic energy armor-piercing projectile cores can greatly improve the lethality of armor-piercing projectiles.

[0003] The United States began to study tungsten and uranium alloys for armor-piercing projectile cores in the 1960s, but depleted uranium bombs were seriously polluted and their use was prohibited. my country began to study tungsten heavy alloys in the early 1960s, and met the scientific and technological requirements in terms of theory, production technology and quality. The needs of development, the application range is also very wide, the current domestic density is less than 15g / cm 3 YK ...
