Complex brass is a type of alloy composed of multiple elements in addition to copper and zinc, which are the two core components of traditional brass. This special variety may contain small amounts of other elements, like lead, tin, aluminum, manganese, nickel and others to grant specific desired characteristics. The use of complex brass is widespread for its various properties – such as increased strength, resistance to corrosion or wear – depending on the composition. It can be found in many industries like aerospace, automotive, marine, electronics, plumbing and musical instruments.
