954 Aluminum Bronze is one of the strongest and most complex of the copper based bearing alloys. Its aluminum additive provides most of its strength, which permits this alloy to be used at unit loads up to 50 percent higher than those of the leaded-tin alloy C932. Because of its high strength, however, it has fairly low ductility and does not conform or embed well. 954 Aluminum Bronze does not have the anti-seizing properties of 932 Bearing Bronze, but it does, however, have excellent corrosion resistance and has superior elevated temperature strength. It has an electrical conductivity rating of 14% IACS. It is available in rounds, flats and squares.
Nickel included in Copper 954 Aluminum Bronze conforms to ASTM B505, SAE J461, SAE J462
The above values are considered average and representative of 954 Aluminum Bronze
954 Aluminum Bronze has a wide range of applications, including bushings, hydraulic valve parts, pump rods, guide pin bushings, gibs, slides, bending tools, bearings, wear plates, screw nuts, gear wheels, worm gears, pickling hooks, spur gears, landing gear parts, valve seats, high strength clamps, pressure blocks, machine parts, etc
954 Aluminum Bronze has a machineability rating of 60% as compared to 360 Brass. Welding, brazing, and soldering of 954 Aluminum Bronze can be performed with standard practices, however, oxyacetylene welding is not recommended.
954 Bearing Bronze can be stress relieved at 600°F. The time at temperature is one hour per 1 inch of section thickness. This solution heat treat temperature is between 1600°-1675°F. The time at temperature is one hour per inch of section thickness. The quenching medium is water.
Annealing
The annealing temperature for this alloy is between 1150°-1225°F. The time at temperature is one hour per inch of section thickness.
