More Information
Summary:A bearing for motorized fuel pumps comprising a graphite-dispersed copper-based sintered alloy which contains 10 to 25% by weight of Zn, 10 to 25% by weight of Ni, 0.1 to 0.9% by weight of P, and 1 to 8% by weight of C, the balance being Cu and unavoidable impurities, and which has a porosity of 5 to 25%, exhibits superior wear resistance to a high-pressure high-speed flow of a fuel.
