ABSTRACT:
Al-alloy containing Si, Fe, Cu and Mg and at least one kind of Mn and Co in the basic composition range of 8.0.ltoreq.Si.ltoreq.30.0 wt. %, 2.0.ltoreq.Fe.ltoreq.33.0 wt. %, 0.8.ltoreq.Cu.ltoreq.7.5 wt. %, 0.3.ltoreq.Mg.ltoreq.3.5 wt. %, 0.5.ltoreq.Mn.ltoreq.5.0 wt. % and 0.5.ltoreq.Co.ltoreq.3.0 wt. %, are provided in a powder state. A sindered member formed of these Al-alloys has a high strength and reveals excellent heat-resistivity and stress corrosion cracking resistivity. A structural member made of the sintered all-alloy is manufactured through the steps of subjecting a powder press-shaped body formed at a temperature of 350.degree. C. or lower and at a pressure of 1.5.about.5.0 ton/cm.sup.2 to hot extrusion working at a temperature of 300.degree..about.400.degree. C. to form a raw material for forging, and then forge shaping the raw material at a temperature of 300.degree..about.495.degree. C.
