Import Casting High Leaded Tin Bronze C93200 — Buy in wholesale FOB from Supplier in China

Casting High Leaded Tin Bronze C93200 is a copper-based alloy with a nominal composition of 83% copper, 7% tin, 7% lead, and 3% zinc, designed for applications requiring superior wear resistance and machinability. This grade conforms to ASTM B505 and SAE 660 standards, making it a reliable choice for industrial components exposed to friction and high loads. The alloy’s microstructure, featuring lead particles dispersed in a copper-tin matrix, ensures low friction coefficients and excellent pressure tightness under dynamic conditions.

The material is particularly valued for its free-machining properties, allowing intricate geometries to be achieved without tool wear, while its thermal conductivity of approximately 50 W/m·K facilitates heat dissipation in high-speed operations. Typical industry use includes bushings, bearings, and valve seats in automotive, marine, and heavy machinery sectors, where durability and self-lubricating behavior are critical. Standard surface finishes for this alloy include as-cast or machined, with tolerances often held to ±0.005 inches for precision parts.

Industrial buyers source C93200 for applications such as pump components, gear assemblies, and corrosion-resistant fittings, where its resistance to galling and seizing extends service life. The alloy is commonly supplied in the form of castings, bars, or plates, with typical packaging in wooden crates or pallets to prevent deformation during transit. For bulk orders, suppliers often provide material test certificates and hardness readings, with Brinell hardness typically ranging between 60 and 80 HB for this grade.
