Brass is an alloy of zinc and copper and is used extensively in marine applications because of its resistance to corrosion. Uses Copper is an excellent conductor of electricity. More than half of the copper consumed is used in electrical generators and motors, electrical power and lighting fixtures, electrical wiring, radio and television sets, computers and almost everything electrical. Copper also conducts heat well and is used for thin-walled copper tubing in air conditioning and refrigeration units, motor vehicle radiators, home heating systems, steam condensers etc. Copper's corrosion resistance and ease with which it can be joined make it suitable for plumbing fittings and water reticulation systems, automotive fuel lines, sea water desalination plants and hydraulic systems.
Copper sulphate is used as a fungicide and as a trace element in fertilisers.
Copper is also used for making coins and scientific instruments and in decorative applications. Haine, I. Copper, in Australian Commodities Forecasts And Issues, Vol.5, No.3, Sept quarter 1998.
