Bronze often use in spare parts of Industry. Such as bearing and rolls. Bearings are also made largely from the 12% - 20% tin-copper alloys, and belts are the principal product made from copper-tin alloys with from 20% to 25% tin. Bronze also use to produce art product like for Gong in Indonesia. Because this metal have good sound and can hear in far distance. See Also: Bronze Application

Copper tin alloys are important on application because of their strength, wear resistance, and corrosion-resistance in a saltwater environment. Copper as main content of this alloy make this alloy metal is resistance to corrode, but have better strength compare with pure copper. Copper tin bronzes may be categorized readily according to their composition, which affects their machine-ability. Alloys with up to 8% tin are used mainly for cold worked applications, such as sheets and coins, those with 8% to 12% tin are used mainly for gears and bearings. See Also: Composition of Bronze

An ancient technology bronze are made from mixing of copper with tin but some alloys that contain no tin are considered bronzes in modern usage, including aluminum bronze (copper aluminum) and silicon bronze (copper silicon). Some copper-base alloys that are actually brasses have been given bronze trade names, such as architectural branze (57% copper, 40% zinc, 3% lead) and commercial bronze ( 90% copper, 10% zinc).

The bronze alloy is among the oldest artificially produced alloys. The bronze age was coined by archaeologists to characterize the period following the neolithic when weapons and tools began to be constructed of bronze. Bronze have been is made by copper metal as base metal and mixed with tin and can be mixed with a little of zinc and phosphorous elements. See Also: Chromic Acid Quality
