C67300 Manganese Bronze

SAE J461, SAE J463

This is a high strength leaded silicon manganese bronze with typically good bearing qualities. This alloy maintains high impact resistance with excellent machinability making it well suited for clutch bearings, shaft bushings, sleeve bearings, thrust bearings, pump parts, drive shafts, bearing pins, wear plates, gears and cams. Resists squashing out under high loads and extreme wear applications.

Typical Uses for C67300 Manganese Bronze:

Typical Applications

FASTENERS: Fasteners, Lead Screw Nuts

INDUSTRIAL: Gears and Cams, Wear Plates, Bushings, Seal Rings, Idler Pins, Piston Heads, Brearing Pins, Thrust Bearings, Sleeve Bearings, Propeller Shafts, Shaft Bushings, Clutch Bearings, Drive Shafts, Spindles, Pump Parts, Bearings

MARINE: Hardware, Valve Seats

OTHER: Connecting Rods
