Tungsten Heavy Alloy

Stanford Advanced Materials (SAM) supplies a wide range of tungsten heavy alloys, including Tungsten Nickel Iron Alloy (W-Ni-Fe Alloy), Tungsten Nickel Copper Alloy (W-Ni-Cu Alloy), Tungsten Bucking Bar (W Bucking Bar), Tungsten Alloy Counterweight Parts, Tungsten Alloy Crankshaft Weight, Tungsten Penetrator (W Penetrator).

Stanford advanced materials (SAM) can provide various big-size tungsten heavy alloy parts by CIP, various small parts by mold pressing, extruding or MIM, various high-strength plates, bars, and shafts by forging, rolling, or hot extruding. Our products have high density and could be a reliable shielding material.

Description & Application of Tungsten Heavy Alloy

Tungsten heavy alloys are made of tungsten-based with two-phase composites of NiFe or Cu as an addition to form a ductile matrix. Tungsten heavy alloys have good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity which make it extensively used in military equipment, balance weights for submarine and vehicles, aircraft components, nuclear and medical shields, fishing and sport tackles.
