Abstract

An alloy of aluminium and 0.05-4.0% of iron or nickel or both, having improved resistance to corrosion by water at high temperatures, is produced by forming alloyed granules of p aluminium and added metal in the required proportions, compressing to form a mass and extruding to produce a shearing effect in at least the portion of the mass adjacent the surface. The granules may be formed by atomizing the liquid alloy or by coating aluminium granules with the added metal, chemically or mechanically, or with a compound of the metal capable of being reduced by aluminium. After reduction, if necessary, the coated granules are heat treated to ensure diffusion of the coating metal and aluminium. Preferably the granules contain as impurities silicon less than 0.01%, zinc, manganese, and magnesium less than 0.005% each, and copper less than 0.01%. In examples given the granules are compressed cold at pressures of 40 or 100 kg/mm2, heated to 600 DEG C. or 620 DEG C. and extruded at 500 DEG C. or 600 DEG C. Preferably additional shearing is caused during extrusion by arranging deviations or constrictions in the vicinity of the extrusion orifice.
