Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Tungsten alloy swaging rod is widely used in industry as well as military areas, such as rifle bullet, armor piercing, snipe rifle penetrator, etc. Tungsten alloy swaging rod is used for YJ-83.
The Yingji-83 (or YJ-83 - Chinese: 鹰击-83, literally "Eagle Strike") is a Chinese anti-ship missile based on the earlier YJ-82 model of the same class. It was designed as a supersonic successor to the subsonic YJ-82. The weapon's export designation is C-803.
