Nickel Aluminum Bronze

C63020 nickel aluminum bronze CuAl11Ni5Fe5, which is manufactured to order in the quench hardened and temper annealed condition. This alloy requires extreme control of the manufacturing process to ensure consistency and high integrity. As well as having good corrosion resistance, C63020 also has excellent wear and anti-galling properties and can be used as a substitute for Beryllium Copper.

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.

AMS 4881 is offered in solid and hollow bars. The additional heat treating process improves mechanical properties and the strength to weight ratio exceeding the range of typical aluminum bronzes. AMS 4881 is commonly used in applications involving heavy loads abrasion, friction, and deformation at high temperatures.

AMS 4880 Nickel Aluminum Bronze is one of the most popular landing gear bushing materials specified today along with AMS 4640 material. NBM's brand of AMS 4880 is continuous cast and heat treated. Our AMS 4880 has outstanding mechanical properties and typically exceeds those of AMS 4640.

AMS 4640 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 alloys strength without diminishing its excellent ductility, toughness and corrosion resistance.

Nickel Aluminum Bronze offers high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.
