Tungsten Nickel Iron alloys (18.8g/cm3) are made of tungsten based two phase composites with Ni, Fe as additions to form a ductile matrix. Tungsten Nickel Iron alloys has good machining properties, excellent radiation resistance, lower expansion coefficient, high strength and modulus of elasticity, which make them extensively used in radiation protection and guidance, balance weights, security and defense etc.
