Abstract
An aluminum alloy containing at least one alloying metal selected from the group consisting of bismuth, cadmium, indium and lead in a quantity greater than the maximum solubility of the metal in solid aluminum. More than 80% by weight of the alloying metals are finely dispersed in a solid aluminum matrix in the form of globules or crystals with a size of less than 5 micrometers. The alloy can be obtained by means of mechanical or electromagnetic agitation of the alloy in the course of solidifying, and in the case of continuously casting a liquid alloy, the agitation can be accomplished by means of an alternating magnetic field which is coaxial to the continuous casting axis.
