Abstract
A copper-lead alloy bearing having a high corrosion resistance, especially a high corrosion resistance to sulfur, comprising a back metal and a copper-lead-based bearing alloy bonded thereto. The copper-lead-based bearing alloy consists of more than 10 but not more than 20% Ni, 0.5 to 8% Sn, 8 to 30% Pb, not less an 0.005 but not more than 0.2% P, and the balance of Cu and incidental impurities.
Claims9
A corrosion-resistant copper-lead alloy multilayer bearing comprising a back metal and a copper-lead-based bearing alloy layer bonded thereto, said copper-lead-based bearing alloy layer consisting by weight of 10.5 to 18% Ni, 0.5 to 8% Sn, 10 to 26% Pb, 0.005 to 0.1% P, and the balance Cu and incidental impurities said bearing having high corrosion resistance to both lubricant with a high sulfur content and corrosive degraded lubricant.
