Product Information
This alloy is a grade of high-ductility brass. By adding manganese, aluminum, lead and silicon the alloy achieves comparable hardness to aluminum bronze, but is much easier to machine. It is used for heavy duty bearings, sliding and contact plates, valves, pistons, etc. CuZn37Mn3Al2PbSi is also known as SoMs58Al2. The synonym is CuZn40Al2.
