ABSTRACT:
A consolidated tungsten alloy body consisting essentially of from about 70% to about 98% by weight of tungsten, balance nickel and iron in essentially an 8:2 weight ratio. A process for producing the consolidated bodies where the tungsten content is greater than about 88% by weight comprises forming a relative uniform blend of the described metal powders, compacting the powders to form a green body then liquid phase sintering the green body to full density. For alloys containing less than about 90% tungsten solid state sintering can be used.
