Aluminum Bronze C61400

The aluminum bronze C95400 is also called C954. It is the most popular and all purpose high yield aluminum bronze alloy with high tensile strength, ductility, welding ability and resistance to wear, fatigue and deformation under shock or overload. The alloy is used while manufacturing bearings, gears, valve components, wear-plate and wear-strip in conformation with continuous cast specification ASTM B505 and centrifugal cast specification ASTM B271.

Typical Uses for C954 Aluminum Bronze:
Automotive : Weld Guns
Fasteners : Nuts, Large Hold Down Screws
Industrial : Pickling Hooks, Bearings, Pawl, Worm Gears, Machine Parts, Spur Gears, Heavily Loaded Worm Gears, Pump Parts, Landing Gear Parts, Valve Bodies, Valve Guides, Valve Seats, Bearing Segments for the Steel Industry, Pressure Blocks for the Steel Industry, High Strength Clamps, Bushings, Valves, Gears
Marine:Ship Building, Covers for Marine Hardware
Ordinance:Government Fittings
