ABSTRACT:
An improved eutectic aluminum-silicon alloy having a relatively high level of bismuth is provided which is particularly wear-resistant and sufficiently self-lubricating so as to be suitable for use in a wearing component even when poorly lubricated. The relatively high bismuth level within the alloy cooperates with the other elemental additions so as to provide a sufficiently low friction bearing surface (or self-lubricity), which significantly enhances the wear resistant properties of the alloy. In addition, the preferred alloy also has relatively substantial additions of both nickel and copper, which results in the homogeneous distribution of hard wear resistant nickel and copper phases throughout. The improved aluminum alloy should minimize wear and alleviate galling during use.
