Single phase tungsten alloy
View Patent ↗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.
1. A metal alloy consisting essentially of:
from 10% to 22%, by weight, of cobalt;
from 30% to 40% by weight, of tungsten;
and the balance nickel and inevitable impurities, said metal alloy having a single phase microstructure and an elongation of at least 50% at 22° C.
2. The metal alloy of claim 1 consisting essentially of:
from 16% to 22%, by weight, of cobalt;
from 35% to 40% by weight, of tungsten;
and the balance nickel and inevitable impurities.
3. The metal alloy of claim 1 being formed into a product selected from the group consisting of a fragmentation warhead, a warhead casing, ammunition, radiation shielding and weighting.
4. The metal alloy of claim 1 being formed into a shaped charge liner.
5. The metal alloy of claim 1 being Conned into an explosively formed penetrator.
