Copper Alloys, Aluminium BronzeAMS 4590 (C63020)

Aluminum-nickel-iron bronze alloy is used in medium to heavy duty applications.

A martensitic product strengthened via heat treatment, it is used where high strength is required in combination with reduced elongation or ductility.

This C63020 nickel aluminum bronze material is used in the aerospace and oil and gas industries for sea water applications in high load yet supported designs.

It has many uses within the aerospace and marine industries, including bushings, landing gear parts, pump parts, washers, track bearings.
