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 HQ-9.
The HQ-9 (Chinese: 红旗; "red flag" or "red banner") is China’s new generation medium- to long-range, active radar homing air defence missile.
The naval HQ-9 appears to be identical to the land-based variant. Its naval type HHQ-9 is equipped in the PLAN Type 052C Lanzhou class destroyer in VLS launch tubes.
