Abstract
An engine bearing having an aluminum-lead bearing alloy and a method of casting such aluminum-lead alloys in which the bimetal lining after bonding of the alloy has no lead gradient and contains no lead ribbons of significant size.
Claims3
An aluminum-lead bearing alloy with a lead content ranging from about 4.0% by weight to about 15% by weight in which the lead phase consists of uniformly distributed spherical particles less than 10 microns in diameter and predominantly 1 to 5 microns in diameter, and wherein the content of any other constituents totals not more than 10% by weight.
