Abstract
A process for producing an aluminum alloy comprises: producing an aluminum alloy powder, consisting of (A) 10 to 36 wt % of Si, 1 to 12 wt % of Fe, 2 to 10 wt % of at least one of metal selected from the group consisting of Ni, Co, Cr and Mn, reminder of the alloy powder consisting of aluminum, or consisting of (B) 10 to 36 wt % of Si, 2 to 10 wt % of Ni, 2 to 10 wt % of at least one of metal selected from the group consisting of Fe, Co, Cr, and Mn, and remainder of the alloy powder consisting of aluminum; compressing a mass of the powder by either compacting the power or accumulating the powder in a can where in case of compacting the powders are so as to have its actual density ratio of 65% to 90%, and in case of the accumulation the powders are compressed so as to have its actual density ratio of not more than 90%; heating the thus compressed mass of powder in convection type heating furnace at a temperature of 250.degree. C. to 550.degree. C. for 5 to 20 hours; and hot extrusion-working the mass of powders at extrusion ratio not less than 4:1, without cooling said heated compressed mass of powders.
