High Tensile Manganese Bronze Hollow Rod

The Manganese Bronze Rod C66800 comes under the category of naval brass and is composed of 60% copper, 39.2% zinc and 0.8% tin. In compliance with typical naval brass, the alloy possesses good strength as well as rigidity. The corrosion resistance towards sea water is achieved due to the presence of zinc in place of tin. The addition of tin also makes the alloy resistant towards dezincification, fatigue, galling, and stress corrosion cracking.

High Tensile Manganese Bronze	C86200

C86300 (SAE 430B) High Tensile Manganese Bronze is ideal for high load, low speed applications that require a combination of outstanding wear characteristics and high bearing strength. Despite its strength characteristics, however, this manganese bronze alloy is not heat-treatable, needs reliable lubrication and should be used in conjunction with hardened shafts. The lead in the alloy's makeup improves machinability without materially affecting its mechanical properties.
