C95400 Aluminum Bronze "9C" (AMS 4871)

CDA 954, C954, ASTM B505, 9C

C95400 Aluminum Bronze, also known by C954, is the most popular, all purpose aluminum bronze alloy. It provides high yield and tensile strength, good ductility, weldability and exceptional resistance to wear, fatigue and deformation under shock or overload. Typical applications include bearings, gears, valve components, wearplate and wearstrip. Conforms to 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
