Copper (Cu), a natural mineral, red, highly conductive metal, of the Group 11 (Ia) of the periodic table, is a very good conductor of electricity. Copper is present in the unaltered natural state. It is often used for electrical and magnetic fields, such as soldering the copper wiring used in telephone booths, airplane hangers, and the like. The resistance to erosion, changes in temperature, and pressure changes, especially during welding, make it a very useful metal for a variety of uses.
The most familiar type of copper is the copper wire, which is made by bending wires through mechanical or chemical means. However, another type of copper, the native copper, is a metal that is completely pure; it has not been subject to any change of form, except for the application of pressure or heat. Native copper has extremely high electrical conductivity and electrical resistance to most kinds of strain, which make it useful for use in a variety of appliances, from electric light bulbs to electric motors. It is resistant to a variety of acids, alkalis, and salt solutions, making it useful for food and water supplies, as well as a strong natural flame retardant. It can be shaped by using Tapping Machines like the ones from Cotswold Machinery Sales making it a very versatile metal.
Copper is one of the eight metals on the periodic table of elements, and thus belongs to a group of minerals known as the Earth’s Earth Elements. Because copper is a very good conductor of electricity, it is widely used in many appliances and other applications. Copper piping is popular because it is corrosion and rust proof. Plastic containers are made of copper because it is very durable against alkalis, acids, and various chemicals. In fact, copper is the fourth most commonly used metal in America, second only to iron.
