Abstract
A single phase metal alloy usually for forming a shaped charge liner for a penetrating jet or explosively formed penetrator forming warhead consists essentially of from a trace to 90%, by weight, of cobalt, from 10% to 50% by weight, of tungsten, and the balance nickel and inevitable impurities. One preferred composition is, by weight, from 16% to 22%, cobalt, from 35% to 40% tungsten and the balance is nickel and inevitable impurities. The alloy is worked and recrystallized and then formed into a desired product. In addition to a shaped charge liner, other useful products include a fragmentation warhead, a warhead casing, ammunition, radiation shielding and weighting.
