Tungsten Alloy Swaging Rod for GBU-57

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 has been widely used for GBU-57.

GBU-57 is a U.S. Air Force, precision-guided, 30,000-pound (13,608 kg) "bunker buster" bomb.[2] This is substantially larger than the deepest penetrating bunker busters previously available, the 5,000-pound (2,268 kg) GBU-28 and GBU-37.

Tungsten alloy swaging rod has high density and high hardness which can help GBU-57 penetrate the rock formation and destroy underground bunker.
