C63000 Nickel Aluminum Bronze - AMS 4640 / CDA 630
C63000 (AMS 4640 - CDA 630) 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 alloys strength without diminishing 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.
