Bronze

Bronze is one of the earliest metals known to man. It is defined as an alloy made of copper and another metal, usually tin. Compositions vary, but most modern bronze is 88% copper and 12% tin. Bronze may also contain manganese, aluminum, nickel, phosphorus, silicon, arsenic, or zinc.

Bronze powder is a flake powder of copper and zinc alloy that varies in color depending on the alloy ratio. Color No. 5 (pale gold) 90 % copper and 10 % zinc.

Bronze Plate is used in a wide range of applications. From wear liners supporting massive extrusion presses to decorative seats for park benches, bronze plates are found in a variety of places. Here at National Bronze Mfg. we consider ourselves the bronze plate experts. We stock bronze plate in a number of alloys and sizes.

Although, at one time, bronze was an 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. To avoid confusion, museums and historical texts typically use the inclusive term "copper alloy." In science and engineering, bronze and brass are defined according to their element composition.
