Grierson, R; Larsen, E I

This invention is directed to the use of tungsten base alloys containing about 1 to 12 wt. percent nickel, about 0.5 to 8 wt. percent iron, and about 0.5 to about 25 percent molybdenum and at least one additional additive selected from cobalt, chromium, manganese, vanadium, tantalum, zirconium, titanium, yttrium, rhenium, boron, and silicon. Chromium may substitute for molybdenum up to 15 percent. In addition to being useful for high-density applications, structural applications, and high-temperature applications, the alloys may be used for die casting dies, molds, cores, and other metal-shaping members. 6 figures, 1 table.
