History of Copper
The discovery of copper dates from prehistoric times. There are reports of copper beads dating back to 9000BC found in Iraq. Methods for refining copper from its ores were discovered around 5000BC and a 1000 or so years later it was being used in pottery in North Africa.
Part of the reason for it being used so early is simply that it is relatively easy to shape. However it is somewhat too soft for many tools and around 5000 years ago it was discovered that when copper is mixed with other metals the resulting alloys are harder than copper itself. As examples, brass is a mixture of copper and zinc while bronze is a mixture of copper and tin. Since then it has evolved significantly and below are the present applications of copper.

Architectural Applications
Copper is heavily employed in the construction industry. It is commonly found in buildings because it is waterproof. This makes it suitable for cladding, roofing and plumbing. It is also applied in freestanding structures because of its light weight and durability. Lightning rods and roofs are often built of copper.
Industrial Applications
The metal’s high ductility
makes it a practical tool for industrial use. It is the third most widely used
metal in industries next to aluminum and iron. It is commonly used in
shipbuilding. The metal is alloyed with nickel.
Uses of Copper in Electricity
More than half of the copper produced is for electricity. Its core functions are transmission of electricity and power generation. The metal is employed in generators, bushbars, motors and transformers. Properly set the metal produces electricity efficiently and safely. The metal is also used in wiring and electrical equipment. It is present in mobile phones, TV and computers.
Practical Daily Application of Copper
The metallic element is applied in fixtures, doorknobs and other elements in a house. Copper electroplated nickel silver is used for some knives, spoons, knives and frying pans. The same material is used for counters, sinks, bathtubs, and heating cylinders. As pigmented salt the metal can be used for sculptures, statues and decorative art.
