It is hard and sonorous, and is used for statues, bells, cannon, etc., the proportions of the ingredients being varied to suit the particular purposes. The varieties containing the higher proportions of tin are brittle, as in bell metal and speculum metal.

2. A statue, bust, etc., cast in bronze.

   A print, a bronze, a flower, a root.

Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, 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.
