<p>Aluminium-tin (Al-Sn) base bearing alloys and bearing materials made by applying said alloys to a backing steel sheet by pressure welding, comprise 7, exclusive, to 35% by weight of Sn; 1, exclusive, to 10% by weight in total of two or more constituents selected from a group of specified additives consisting of Cr, Si, Mn, Sb, Ti, Zr, Ni, Fe, W, Ce, Nb, V, Mo, Ba, Ca and Co, wherein 1, exclusive, to 10% by weight of Cr is contained; and the remainder of aluminium. The alloy can further contain 3% by weight or less in total of Cu and/or Mg and 9% by weight in total of one or more constituents selected from a group consisting of Pb, Bi, Tl, Cd and In, thereby improving the bearing characteristics. Bearing alloys according to the invention may be used for the bearings of internal combustion engines in which spheroidal (nodular) graphite cast iron is used for crankshafts.</p> |
