Bronzes are harder than brasses . Most are produced by melting the copper and adding the desired amounts of tin, zinc, and other substances. The properties of the alloy depend on the proportions of its components. Silicon bronze is used for telegraph wires and chemical containers.
Phosphor bronze is used for springs.
Bronze is used for coins, medals, steam fittings, and gunmetal and was formerly employed for cannon. Bronze has long been used in art, e.g., for castings, engravings, and forgings. Listing from Electric Library , a pay service. Copyright 2001 Infonautics Corporation . All rights reserved.
