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.

Phosphor bronze is an alloy of copper with tin and phosphorus, which has higher corrosion resistance, wear resistance, and no sparking when impacted. Used for medium speed, heavy load bearing, working temperature up to 250 ℃. With self-aligning, insensitive to deflection, and high load-bearing capacity can be subjected to radial load at the same time, self-lubrication without maintenance and other characteristics.

Graphite Embedded Phosphor Bronze

With phosphor bronze as the metal base material, embedded in graphite or other solid lubricants, under the action of frictional heat in operation, the lubricant is heated and expanded and automatically transferred to the friction surface, forming a layer of solid lubricating film, isolating the direct contact between the two friction surfaces, thus reducing the friction factor and friction loss, and improving the bearing capacity. Graphite-based solid lubricant embedded in the slider, thrust bearing, pad, and other parts of the relative movement of the surface can also achieve the self-lubricating effect.
