Aluminium bronze

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper (for alloys with aluminum as the major component, see aluminum copper alloy), in contrast to standard bronze (copper and tin) or brass (copper and zinc). A variety of aluminium bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminium by weight, the remaining mass being copper; other alloying agents such as iron, nickel, manganese, and silicon are also sometimes added to aluminium bronzes.
