Because of these properties and can be combined with zinc, lead, nickel, aluminum and titanium into alloys and other properties, is widely used in electrical appliances, machinery, vehicles, shipbuilding industry and civil appliances and other aspects. For example, the use of copper to make wires, cables, electrical equipment; oxygen-free copper to make ultra-high frequency electronic tubes, brass manufacturing gun and artillery shells; white copper (copper-zinc-nickel alloy) to make the elasticity of aviation instruments; tin bronze to make bearings, bushings and so on. Copper compounds are used in agriculture as insecticides and herbicides; copper is also the main raw material for the manufacture of anticorrosive paints.
