ABSTRACT:
A tungsten based sintered alloy has excellent corrosion resistance under high temperatures and high humidities, and has good toughness. The alloy can be employed as such without requiring further corrosion protection such as Ni plating, due to its corrosion resistance, and allows for plastic deformation such as caulking, due to its toughness or good elongation. The tough corrosion-resistant tungsten based sintered alloy consists of 80 to 97 percent by weight of tungsten, and a remainder of Ni, Co, and optionally Fe and unavoidable impurities. The alloy most particularly has a Co content of at least 2 and not more than 60 percent by weight, an Fe content of more than 0 and less than 5 percent by weight, and a remainder of Ni in a Ni--Co--Fe binder phase.
