  3. Major applications of copper • electrical wires (60%) • roofing and plumbing (20%) • industrial machinery (15%) • make an alloy (5%) *Example of alloies: brass and bronze bronze brass

  4. Everyday uses of copper • doorknobs and other fixtures in the house • cooking utensils • copper bath tubs • copper counters • decorative art • an essential nutrient to all higher plants and animal life

  5. Copper in alloys • the most important constituents of carat silver and gold alloys and carat solders • used in the jewelry industry, modifying the color, hardness and melting point of the resulting alloys • e.g. Brass(alloy of copper and zinc and bronze) • e.g.cupronickel(alloy of copper and nickel)

  6. Industrial Uses of Copper • Watt's steam engine firebox • wood preservative • coins • plumbing, roofing and cladding • helping in providing hygienic surfaces
