About

CNC machined Copper C932, also known as SAE 660 bearing bronze, is a copper-tin-lead alloy specifically designed for applications requiring excellent wear resistance, low friction, and reliable performance under load. This material is widely used in mechanical systems where components experience continuous motion, sliding contact, or heavy loads.

Copper C932 also offers good corrosion resistance in atmospheric and industrial environments, as well as excellent resistance to galling and seizure when operating against steel shafts. Its lead content improves machinability and contributes to smooth, low-friction operation in bearing applications.
