Traditional bronze is a copper alloy with up to 10% tin. The tin in bronze makes it more resistant to wear than unalloyed copper. Bronzes today are usually stronger and more resistant to corrosion than brass. Contemporary bronzes are typically copper alloys that may contain silicon, manganese, aluminium, lead, iron and other elements, with or without tin. The variations in bronze composition significantly affect its characteristics. Wearability, machinability, corrosion-resistance and ductility for deep drawing are often considered. Bronze parts are typically used for bearings, clips, electrical connectors and springs. Combro, or commercial bronze, is 90-10, or 90% copper/10% tin. It is frequently the least expensive, most easily obtained grade of bronze. Aluminium bronze is a copper-aluminium alloy that may contain iron, nickel, and/or silicon for greater strength. It is used for tools and, because it will not spark when struck, for parts to be used around flammable materials. Aluminium bronze is frequently used for aircraft and automobile engine parts. Manganese bronze is actually a brass containing manganese. It is often used for ship propellers because it is strong and resists saltwater corrosion.
