ABSTRACT:
A shaft bearing is formed from an aluminum alloy that has approximately 8% Sn, 4% Si, 2% Pb and 1% Cu on a weight percentage basis. The tin has an average particle size less than five microns and the silicon has an average particle size less than 3.5 microns. The alloy is 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 is pressure bonded to a steel backing strip to form a composite strip useful in forming a shaft bearing. During the pressure bonding step the thickness of the aluminum alloy strip is significantly reduced while the thickness of the steel strip remains essentially unchanged.
