Machinability Tungsten Heavy Alloy Sheet / Plates Thickness 0.06mm to 100mm WNiFe

Tungsten Heavy Alloys are materials with a high tungsten content and low amounts of Ni, Fe or Ni, Cu. Some tungsten alloy is added Co, Mo or Cr etc. Their densities could be as high as 16.8~18.8g/cc.

The majority of current uses for WHAs are best satisfied with the W-Ni-Fe system. such as 93W-4.9Ni-2.lFe and 95W-4Ni-lFe represent common compositions. The addition of cobalt to a W-Ni-Fe is a common approach for slight enhancement of both strength and ductility.

The presence of cobalt provides solid-solution strengthening of the binder and slightly enhanced tungsten-matrix interfacial strength. Cobalt additions of 5 to 15% of the nominal binder weight fraction arc most common.
