Product description

Tungsten alloy metals, mainly including W-Ni-Fe and W-Ni-Cu, are widely used in military equipment, mechanical engineering, aircraft components, medical shields and sports equipment.
W-Ni-Fe alloys are used in collimators and shielding components to provide protection against X- and gamma-ray radiation. Products manufactured from tungsten, nickel and copper are distinguished by their non-magnetic behavior. This material is used where magnetic interference is avoided.

Product Features

Large specific gravity: the specific gravity is generally 16.5-18.75g/cm³;

High strength: the tensile strength is 700-1,000Mpa;

Strong ray absorption capacity: 30-40% higher than that of lead;

Large heat conducting coefficient: the heat conducting coefficient of tungsten alloy is 5 times that of mold steel;

Small thermal expansion coefficient: 1/2-1/3 of that of iron or steel;

Good conductivity: it can be widely applied to illumination and electric welding industries because of its good conductivity;

Good weldability and machinability.
