C86300 Manganese Bronze is a non-lead “GREEN” Alloy
Manganese Bronze CDA 863
SAE 430B
ASTM B505

Manganese bronze is a very hard and strong bronze. Good applications include heavy earth moving equipment, roll neck bearings, and machine tool bearings.

Solid and cored bars are stocked in 13" increments and 144" lengths, and are available in other lengths and non-standard sizes. Consider bars for use when you need special bearings, bearings for prototypes, or for emergency repairs.
