Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals (such as aluminium, manganese, nickel or zinc) and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon. These additions produce a range of alloys that may be harder than copper alone, or have other useful properties, such as stiffness, ductility or machinability.
What Is Bronze?
Bronze is one of the earliest metals known to man. Here is a look at the chemical composition and properties of bronze.
Bronze is an alloy made of copper and another metal, usually tin. Compositions vary, but most modern bronze is 88% copper and 12% tin.
Although at one time bronze was any alloy consisting of copper with tin and brass was an alloy of copper with zinc, modern usage has blurred the lines between brass and bronze. Now, copper alloys generally are called brass, with bronze sometimes considered a type of brass.
Bronze usually is a golden hard, brittle metal. The properties depend on the specific composition of the alloy as well as how it has been processed.
