ABSTRACT:
An Al alloy suitable for use as the material of a sliding part such as those in automotive internal combustion engine. The alloy consists essentially of: more than 11 weight % but up to 18 weight % of Si, more than 3 weight % but up to 10 weight % of Sn, not smaller than 0.2 weight % but less than 2 weight % of Cu, and the balance substantially Al. Pb may be added to improve the anti-seizure property and the compatibility. One, two or more elements selected from a group consisting of Na, Sr and P may be added to make fine the Si grains. The alloy can further contain also at least one element selected from the group consisting of Mn, V, Cr, Ti, Mg and Fe in order to further improve the mechanical properties, particularly the strength. This alloy exhibits superior anti-seizure property and high wear resistance and, hence, can be used suitably as the material of various sliding parts.
