ABSTRACT:
A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 2.5% Si, 2% Pb, 0.8% Cu and 0.2% Cr on a weight-percentage basis. The tin has an average particle size less than 5 microns and the silicon has an average particle size less than 5 microns. The alloy may be formed into a continuous solid strip by a quench casting operation, wherein molten alloy is fed into an interface between two internally-cooled rolls to freeze the alloy into a solid strip condition in less than one second. The aluminum alloy strip can be pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing.
