<p>Al-Sn-Pb alloy system used as bearing comprising in wt. percent: Sn:3-35, Si: 0.1-11, Pb: 0.1-10, one or more among Cu, Mg, Zn, Cr, Mn, Fe, Ni, Co, Mo, Sb, Ti, V and Zr: 0.1-4 in total and the balance virtually of Al, in which 0.3 or less of Sr has been added so that Si particles be made dispersed in Al matrix with round shape at edge. A alloy is very lubricative and durable to withstand severe service conditions under high load and has highly favorable mechanical properties at any temp. within a range of 100-250 deg.C.</p> |
