SPECIFICATION CROSS-REFERENCE CHART

Manganese bronzes alloys can operate under very high loads and speeds. However, bearing applications require reliable lubrication. Besides excellent mechanical qualities, these alloys have good corrosion resistance. The standard alloy in this group is high tensile C86300, which is comprised of copper, manganese, aluminum and iron. This combination raises the tensile strength to over 110,000 KSI.
