Tungsten heavy alloys are the tungsten alloys consisting of W-Ni-Fe or W-Ni-Cu. The tungsten content varies from 90% to 98%. Nickel, iron and/or copper serve as a metal binder matrix, which makes the tungsten alloys ductile and easy to machine. Tungsten heavy alloys have a high melting point, high density, a low thermal expansion coefficient and high strength.
We can offer tungsten heavy alloys under the Mil-T-21014 standard with various dimensions in forms of plates, rods or others on request. The W-Ni-Fe alloy is slightly magnetic while W-Ni-Cu is not.
Application: As balancing weights, high temperature molds, protection shields, armor piercing shells and etc. Tungsten heavy alloys are widely used in the national defense industry, the aerospace industry and the civil industry.
