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.
