ALUMINUM ALLOY FOR SLIDE BEARING AND SLIDE BEARING

摘要

PROBLEM TO BE SOLVED: To provide an Al-Sn-Si type slide bearing alloy which makes Fe contained as an impurity harmless and prevents a tool from forming a built-up edge during cutting of a slide bearing.SOLUTION: An aluminum alloy for slide bearings comprises 2-18% Sn, 2-7% Si, 0.05-1.5% Fe and remaining Al and unavoidable impurities, and Si particles and an Si-free Fe phase are dispersed in an Al matrix.
