Abstract
This invention relates to Al bearing alloy and a two-layer bearing material consisting of a bearing layer of said Al bearing alloy and a backing metal consisting of a steel sheet or the like. More particularly, the invention concerns an Al bearing alloy, which contains an aluminum alloy matrix having 2 to 35% of Sn, 0.5 to 10%, of Si, 0.1 to 10% of Pb, 0.01 to 0.3% of Sr and 0.01 to 0.3% of Sb, the balance being substantially Al. Additional constitutents may be 0.1 to 4% in total of at least one member selected from the group consisting of Cu, Mg, Zn, Cr, Mn, Fe, Ni, Co, Mo, Ti, V and Zr. The Si is precipitated as Si precipitate particles having spherical or oval shape or a shape having rounded ends in an Al matrix consisting substantially of Al and also Sn-Pb alloy particles are precipitated in the vicinity of the Si precipitate in the Al matrix so that it has improved fatigue-resistant properties, anti-seizure properties and abrasion-resistant properties under high speed, high load running conditions of the automobile.
