HQ-9

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.

The land-based HQ-9 system has an anti-radiation variant, known as the FT-2000 for export. The export designation for air defense version is FD-2000 (with FD stands for Fang Dun, meaning defensive shield), and its developer China National Precision Machinery Import and Export Corporation (CPMIEC) first made it public at the Africa Aerospace and Defence Exhibition held at Cape Town in March 2009. In September 2013 the HQ-9 submitted by CPMIEC won Turkey's T-LORAMIDS program to co-produce 12 long range air defense systems.
