Abstract

An alloy comprising at least two refractory metals having melting temperatures differing by at least 200.degree. C., and being present in proportions by weight such that solidification begins at a temperature at least 150.degree. C. less than the solidification temperature of the metal having the highest melting point. The alloy is produced by coelectrodeposition, and is in the form of conglomerates of dimensions between 0.2 and 30 mm of crystals of size 0.1 to 1 mm, in which the refractory metals are in a solid solution state.
