<p>PURPOSE:To obtain a bearing Al alloy with superior fatigue resistance and/or anti-seizure properties, by adding one or more among Ni, Mn, Cr, V, Mg, etc. to an Al-Pb-Sn-Cu-Si alloy. CONSTITUTION:This bearing Al-Pb alloy consists of, by weight, 9.0-40% Pb, 0.2-5% Cu, 0.2-10.0% Sn, 0.1-10.0% Si, 0.01-3% one or more among Ni, Mn, Cr, V, Mg, Ti, Zn, Co and Zr, and the balance Al with inevitable impurities. To said composition may be added 0.1-3.0% one or more among Sb, Bi, Cd and In. The bearing Al-Pb alloy is much superior to a conventional Al-Sn alloy in fatigue resistance and/or anti-seizure properties.</p> |
