Tungsten Alloy Swaging Rod for DF-21

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.

Advantages of tungsten alloy swaging rod: low cost, easy operation, convenient processing adjustment and control, harder, more durable, excellent hardness (40HRC, tungsten alloy rod between 26HRC and 30HRC), high ultimate tensile strength (1200MPa~1400MPa), etc.

Tunsgten alloy swaging rod can be used for DF-21 which can anti flying carrier.

The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng (Chinese: 東風; literally "East Wind") is a two-stage, solid-propellant, single-warhead medium-range ballistic missile (MRBM) in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985-86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers.

Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. As well as a nuclear warhead of around 300 kt, it is thought that high explosive, submunition and chemical warheads are available. The latest DF-21D was said to be the world's first anti-ship ballistic missile (ASBM). The DF-21 has also been developed into a space-capable anti-satellite/anti-missile weapon carrier.
