ABSTRACT:
An aluminum alloy for pistons and a method of manufacturing pistons making use of said alloy, enabling casting without sacrificing the ease of casting, and restricting deformation and melting at high temperatures, and fatigue and wear caused by high speed sliding movement. The aluminum alloy contains Si+SiC in an amount in the range of 8% to 20% by weight, and SiC in an amount of 2% or more by weight. An ingot containing the aluminum alloy is melted, sprayed in the state of mist, rapidly cooled and solidified into rapidly cooled powder. The rapidly cooled powder is heated and solidified into a blank from which the piston is forged, heat-treated, and machined.
