ABSTRACT:
An aluminium alloy made of consolidated rapid-quenched aluminium alloy powder by using an improved metallurgical method basically comprises, by weight percent, less than 30% silicone, less than 8% iron, less than 7% copper and less than 0.2% oxygen, the balance being substantially aluminium. The consolidated rapid-quenched aluminium alloy powder has features that it contains less than 0.2% oxygen, and the material made from the rapid-quenched aluminium alloy powder has a high limit compressibility factor, rate of reduction and tensile strength. Thus the aluminium alloy material obtained is suitable for structural members such as pistons for internal combustion engines.
