Leaded Bronze

Saru Copper offers a premium range of Leaded Bronze alloys manufactured using high-grade raw materials and advanced continuous casting technology. Supervised by our team of metallurgical experts, our Leaded Bronze rods, hex bars, flats, and custom profiles are designed for applications demanding exceptional machinability, resistance to wear and corrosion, and long service life.

These alloys are ideal for medium-load, low-speed bearing applications, offering excellent performance in abrasive and corrosive environments, especially where lubrication is limited.
