BRONZE BASED ALLOYS
C86300
CAST C86300
Manganese bronze alloys, such as C863, 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 combination of copper, manganese, aluminum and iron in C86300 raises its tensile strength to over 110,000 KSI.
