Phosphor bronze alloy is a widely used bushing material in the automobile industry, widely used in air compressors, refrigeration machines, internal combustion engine connecting rod small head bushing, crosshead pin bushing, piston pin bushing, camshaft bushing, guide wheel bushing, guide wheel bracket bushing, gearbox bushing, etc. It is characterized by high hardness, good wear resistance, low friction coefficient, good impact toughness, high permissible specific pressure and ultimate linear velocity, and good workmanship. Phosphorus in phosphor bronze can prevent the production of extremely hard and brittle Sno2 in the alloy, the journal has a protective effect. Therefore, the use of phosphor bronze bushings as parts in automotive manufacturing helps extend the mechanical life.
A combination of centrifugal casting, cold extrusion, and machining. The production of phosphor bronze bushings with this process can achieve good quality, high material utilization, saving man-hours and cost savings.
