An aluminum-lead bearing alloy (42) in continuously cast strip form has a lead content in excess of 1 % by volume, 4 % by weight. The lead phase consists of uniformly distributed spherical particles (16) no more than 25 microns in diameter, and the content of all other constituents other than aluminum totals not more than 10 % by weight, the balance being aluminum. The alloy is used in engine bearings wherein an aluminum-lead alloy lining (12) is bonded to a steel backing (14).
