Brass is made from an alloy of copper and zinc, with a maximum of 40 percent zinc content. Bronze also has a similar composition, although it contains more copper than brass. It can also have other metal additives in its composition, such as lead, aluminum, manganese, tin, iron, chromium and silicon. The melting point of brass is 1,000 degrees Celsius, although zinc begins to evaporate from brass at temperatures as low as 907 degrees Celsius. Due to its lower copper content than bronze, brass has a lower price.
Brass sheets and other products made from brass are orange-yellow in color, slightly lighter than pure copper. Brass resists corrosion, is easily machined, has casting properties and is easily malleable.
Brass can be used to make machine and appliance parts, door handles, fittings for the bathroom or kitchen, or construction hardware and ammunition. Brass is used to make coins, medals, cups, candlesticks or mortars.
E-invest has a range of cast brass molds, including brass sheets, rods, brass pipes, etc.
