Phosphor bronze is a widely used bushing material in automobile manufacturing, such as rod small head bushings, crosshead pin bushings, piston pin bushings, camshaft bushings, guide wheel bushings, guide wheel bracket bushings, gearbox bushings, etc. in air compressors, freezers, and internal combustion engines.
It is characterized by high hardness, good wear resistance, low friction coefficient, good impact toughness, high permissible specific pressure and ultimate linear speed, and good workmanship. Phosphorus in phosphor bronze can prevent the production of extremely hard and brittle SnO2 in the alloy, which has a protective effect on the journal. Therefore, the use of phosphor bronze as a metal material, helps extend the mechanical life.
