Abstract
A highly wear-resistant aluminum-based composite alloy has improved wear resistant itself and the wear amount of the opposed Fe-based material is decreased as compared with the conventional wear-resistant aluminum alloys. The inventive composite alloy has a structure that at least either a dispersing phase selected from the group consisting of hard fine particles or a solid-lubricant particles having average diameter of 10 um or less is dispersed in an aluminum-alloy matrix which contains quasi-crystals.
