C63000 Nickel Aluminum Bronze
Spec Equivalents: AMS 4640, SAE J463, QQ-C-465B, ASME SB150, ASTM B-150, B-124, B-171, B-283
C63000 (AMS 4640 – CDA 630) Nickel Aluminum Bronze alloy is an excellent choice for applications involving heavy loads, abrasive wear resistant, friction, abrasive wear and corrosion. The addition of nickel increases the strength of alloy without effecting its excellent ductility, toughness and corrosion resistance. Typical applications for C63000 nickel aluminum bronze included aircraft landing gear components, strut bearings, main pistons, trunnion bearings and similar vital components.
