We offer c66800 manganese bronze for producing pump parts and marine hardware. This alloy is suitable to operate under high load and speed bearing applications. It is commonly used to produce gears, cam shafts, drive shafts, sleeve bearings, piston head, idler pins, thrust bearing and spindles. The addition of manganese makes this alloy most wear resistant with great toughness and ductility. This alloy possesses bending, coining, knurling, roll threading, spinning and shearing, stamping, and swaging fabrication process. It also holds good hot and cold workability and forge-ability. The provided c66800 manganese bronze has good corrosion resistant when submerged in salty water.
