Nickel Aluminium Bronze AMS 4590 (UNS C63020)
Technical Data Sheet
|Chemical Composition Limits|
C63020 (AMS 4590) is a Nickel Aluminum Bronze which is available in solid bar - AMS 4590
A special heat treatment process improves the mechanical properties beyond the range of commercial aluminum bronzes. This alloy is an extra high strength version of nickel aluminum bronze. It is used where parts require extra high strength and hardness with some ductility and toughness. Typical applications include military aircraft bushings involving heavy loads, abrasion and high deformation. The extra high strength characteristics provide extreme wear resistance for extreme loads, abrasive wear, and high impact landings (such as aircraft carrier landings).
