Tungsten Nickel Iron Alloy Description

Tungsten nickel iron contains 1% to 3% of iron and 1% to 7% of nickel composited at ratios ranging from FeNi 1:1 to 1:4. The 1% to 3 % of iron additive is responsible for significant differences in tungsten alloys containing nickel iron exhibit, comparing tungsten alloys containing nickel copper. First, tungsten nickel iron is ferromagnetic material because of the iron. Iron imparts other special attributes to tungsten nickel iron, such as its comparatively higher density, melting point, ductility, and strength. By virtue of these excellent properties, tungsten nickel iron alloys have better high-temperature strength and higher cold-work deformation rate than tungsten nickel copper. All these allow it to be used in many industries including sports, medicine, etc. Tungsten nickel iron is a high-density alloy suitable for high-temperature environments and applications such as bearing assembly, ballast, casting, step soldering, and radiation shielding.

Tungsten nickel iron alloys are available in numerous machined shapes such as bar, ingot, ribbon, wire, shot, sheet, and foil, in various dimensions. We can also produce materials to custom specifications by request.
