C63020 Nickel Aluminum Bronze AMS 4590

C63020 AMS 4590 Nickel Aluminum Bronze is an extra high strength nickel aluminum bronze alloy. This alloy is heat treated and martensitic. C63020 is the strongest in the Nickel Aluminum Bronze family and sometimes can be a substitute for Beryllium Copper. Originally developed for aircraft components in retractable landing assemblies, this alloy is ideal for applications involving very heavy loads, extreme abrasive wear, corrosion service, friction, deformation, and high temperatures.
