Product Description

C63000 Nickel Aluminum Bronze (AMS 4640) is an extruded or forged wrought aluminum bronze that contains nickel, and is alloyed for exceptional strength and toughness. It’s used where higher mechanical properties are required. It’s used in equipment for the energy markets, in aircraft, marine and a host of other industrial applications. It finds use as valve stems, high strength bushings, valve guides and seats, gears, cams, ship propellers, as well as propeller nuts and shafts. Larger rounds, ring and shapes can be forged and rough machined. The temper on rounds up to 3″ diameter is HR50, drawn and stress relieved, over 3″ diameter the temper is TQ50, quench hardened and temper annealed. In the forged state the temper is TQ50, quench hardened and temper annealed or 020 temper, hot forged and annealed.

Other terms for this alloy are: C63000 Nickel Aluminum Bronze Bar or Rod, AMS 4640, C630, ASME SB150, ASTM B150/B150M, ASTM B124/B124M, SAE J461; SAE J463

Notice: The weights listed are the best estimates of the actual weights we will ship. They are a combination of the calculated theoretical weights and an average of actual weights. Our weights are conservative to the heavier side but there may be slight variations in weight from bar to bar.

The Physical, Fabrication and Thermal Properties shown here represent reasonable approximations suitable for general engineering use. Due to commercial variations in compositions and to manufacturing limitations, they should not be used for specification purposes.
