About Copper

Copper is a soft metal resembling gold in its color and texture. It is known as one of the oldest discovered metals, and humanity worked with copper millions of years ago. It has got its current name from a Latin word meaning metal from Cyprus. Copper is essential for living creatures, and we have it in our bodies in small doses, for proper function of our enzymes. It is possible to find copper in its pure form in nature, but it is usually obtained from natural minerals. Centuries ago, copper was considered to be a precious metal and was used to produce coins, along with gold and silver. Besides, copper is extensively used in producing electrical element, especially wires or others. Together with tin, copper forms an alloy named bronze, which is used for producing kitchenware, valves, gears, electrical components, bells, and so on. Another famous alloy of copper – the one with zinc – is called brass, and it is widely used for producing parts of musical instruments, screws, buttons, door knobs, and many other things.

Uses of Copper

Copper, a reddish and ductile metallic element with the symbol Cu, is mainly used as a conductor of electricity and heat. Copper and its useful alloys are employed in the medical field and in agriculture. Cuprous oxide is used as a pigment in glasses, porcelain, paints, and ceramics. Cupric sulfate is mostly used for agricultural purposes. Cuprous chloride is generally used as a catalyst. Cuprous sulfide is used in electrodes, solar cells, etc. Sterling silver, an alloy of silver and copper, is used in forks, spoons, knives, medical instruments, as well as in the manufacture of saxophones. Monel, an alloy of nickel, copper and small amounts of iron, carbon, manganese, silicon, is preferred in aircraft construction, buildings, oil production, piping systems, musical instruments, the chemical industry. Monel is also used in the frames of eyeglasses and even in motion picture film processing.
