Description
Introduction of Tungsten Alloy swaged rod：
Tungsten alloy rod made by through rotary forging. The methods commonly used in processing include extrusion, forging and sintering. The normal tungsten alloy rod after swaging, ultimate tensile strength and hardness would be increased greatly. The ultimate tensile strength of general tungsten alloy rod is 920 MPa, hardness is 25HRC. However, after swaging, the ultimate tensile strength can reach 1200 MPa, hardness is 35HRC. We could even control at 1400 MPa, 40HRC. This type of rod is one of our main products. Usually the composition of this kind of products is 92%WNiFe.
Appliance of tungsten heavy alloy swaged rod：
Tungsten alloy swaged rod has longer service life. Tungsten alloy swaged rod is widely used in military field, can be used as rifle bullets, armor piercing bullets, anti-equipment sniper rifle bullets. It is also can be used in machining, CNC tooling, anti-seismic mill holder etc.
