Gunmetal

Gunmetal is a type of bronze – an alloy of copper, tin, and zinc.cite web | last = | first = | title =Gunmetal | url=http://www.encyclopedia.com/doc/1E1-gunmetal.html | accessdate = 2008-04-09] Originally used chiefly for making guns, gunmetal was superseded by steel. It is called red brass in America. [cite web | last = | first = | title =Gunmetal | url=http://www.diracdelta.co.uk/science/source/g/u/gunmetal/source.html | accessdate = 2008-04-09] Gunmetal is resistant to corrosion from steam and salt water, and is thus suitable for valves, pump parts and steam fittings.cite web | last = | first = | title =Gunmetal | url=http://www.britannica.com/eb/article-9038526/gunmetal | accessdate = 2008-04-09]

Gunmetals produced for different purposes vary slightly in composition. In some cases, the alloy may be composed only from copper and tin, or from copper, tin, and lead. It has many uses in industry, and is used for statues and various small objects, e.g. buttons. U.S. Government bronze specification G is a gunmetal composed of 88% copper, 10% tin, and 2% zinc. U.S. Government bronze specification H is composed of 83% copper, 14% tin, 3% zinc, and 0.8% phosphorus.Fact|date=April 2008

Gunmetal can also mean steel treated to simulate gunmetal bronze. Brushes made of this metal are used in machinery.

Other uses

The British Victoria Cross, the highest award for military valour, is made using metal from a cannon captured at the Siege of Sevastopol during the Crimean War.
