P/M aluminium alloy made from incorporating the rapidly-solidified aluminium alloy powders and hot working, for example, extrusion or forging, possesses excellent properties such as low thermal expansion coefficient, excellent wear resistance, and high strength. Therefore, in Japan, the technologies on powder-extrusion and powderforging of aluminium alloy powders are developed for ten years, and applied to many components, such as rotors and vanes of compressors for car air conditioners, orbital scrolls of compressors for room air conditioners, cylinder liners of motor cycle engines, and so on. In this report, the applications such as rotors and vanes are presented, and the industrial technologies on near-net-shape extrusion with good dimensional accuracy and without cracks or defects are described. Moreover, cylinder liners made of particle-dispersed composites with fine alumina and graphite, which are recently manufactured in mass production, are in detail mentioned.
