摘要： A tin-base white metal bearing alloy essentially consists of, by weight, more than 3% and up to 15% Sb, more than 2% and up to 10% Ni, more than 0.001% and up to 1% Cr, up to 9% Cu, and balance of Sn and incidental impurities. Since Ni increases the strength at high temperature and the melting point, heat resistance and fatigue resistance as a tin-base white metal bearing alloy are improved. In this case, the strength will be further improved by containing at least one element of Cd, Be, Co and Mn whose amount or total amount is more than 0.1% and up to 5% by weight.
