A consolidated tungsten alloy body consisting essentially of from about 88% to about 98% by weight of tungsten, balance, nickel and iron, produced by liquid phase sintering, containing a continuous phase of a tungsten, nickel and iron alloy and a discontinuous phase of elongated grains of tungsten having an aspect ratio of at least 4:1 relatively uniformly distributed throughout the continuous phase and wherein said body has a recrystallization temperature of from about 1000 DEG C. to about 1200 DEG C. A process for producing the consolidated bodies comprises working and annealing at controlled temperatures to achieve the desired properties. The working temperatures are from about 700 DEG C. to about 900 DEG C. and the annealing temperature is preferably 1200 DEG C.
