  • Copper-base bearing material containing corrosion-resistant lead alloy
    Patent number: 3969084
    Abstract: A Pb-base alloy containing 1 - 3% Sn and 0.5 - 3.5% Bi, allowing less than 2% Sb to be further contained, resists attack from acids formed in deteriorated lubricating oils. Either an alloy of Cu and the Pb-base alloy or a porous Cu mass impregnated with the Pb-base alloy is a highly corrosion-resistant bearing material, and the Pb-base alloy serves also as a direct overlay on a Cu-base bearing material due to negligible heat diffusion of Sn from the alloy.
