C93700 High Leaded Tin Bronze "80-10-10"

AMS 4842, ASTM B505, SAE 648

C93700 has excellent machining properties at 80%, medium strength and good corrosion resistance and will withstand mild acids as found in mine water. Bearings manufactured from C93700 have excellent wear resistance under conditions of high speed, heavy pressure and vibration, have low friction and can be used where lubrication is less than adequate and there may be minor misalignment. C93700 bearings require a hardened shaft and maximum shaft surface speeds of 4 m/sec can be tolerated.åÊ

Typical Uses for C93700 High Leaded Tin Bronze "SAE 64":

BUILDERS HARDWARE: Brackets

FASTENERS: Washers for Engines, Nuts

INDUSTRIAL: Crank Shafts, Bushings, Machine Parts, High Speed, Heavy Load Bearings, Pumps, Pressure Tight Castings, Impellers, Corrosion Resistant Castings, Bushings for high speed and heavy pressure., Applications Requiring Acid Resistance to Sulphite Fluids, Bearings, Bearing Plates, Parts for Steel Mill Maintenance, Slide Guides for Steel Mills

MARINE: Large Bearings for Ships
