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 9K34 Strela-3.
The 9K34 Strela-3 (English: arrow) man-portable air defence missile system (MANPADS) was developed in the Soviet Union as a response to the poor performance of the earlier 9K32 Strela 2 (SA-7 Grail) system. "9K34" is its GRAU designation and its NATO reporting name is SA-14 Gremlin. The missile was largely based on the earlier Strela 2, and thus development proceeded rapidly. The new weapon was accepted to service in the Soviet Army in January 1974.
