C63000 Introduction

Aluminum is the main alloying metal added to copper in aluminum bronze alloys such as C63000, also known as C630. A variety of aluminum bronzes of differing compositions have found industrial use, with most ranging from 5.00% to 11.00% aluminum by weight, the remaining mass being copper. Other alloying elements such as iron, nickel, manganese, and silicon are also oftentimes added. Aluminum bronzes are most valued for their high strength and corrosion resistance.

C63000 Nickel Aluminum Bronze – AMS 4640 / CDA 630

Standards: ASTM B-124, ASTM B-150, ASTM B-171, B-283, SAE J461, SAE J463, AMS 4640F, AMS 4880B, DIN 2.0966

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.
