Tungsten Alloy metals are mainly including W-Ni-Fe and W-Ni-Cu, are extensively used in military equipment, mechanical manufacturing, aircraft components, medical shields and sports equipment. WNiFe/WNiCu tungsten heavy tungsten heavy alloy WNiFe tungsten nickel ferro/iron alloy.
W-Ni-Fe alloy is used in collimator and shielding components to provide protection against X-ray and γ-ray radiation. A product manufactured from tungsten, nickel and copper, is distinctive due to its non-magnetic behavior. This material is used in the places to avoid magnetic interference.
