Discovery: Copper has been known since prehistoric time. It has been mined for more than 5000 years.
Element Classification: Transition Metal
Copper is a very tough yet flexible metal. It was one of the first metals used by humans to make weapons and tools. Pure copper is red in color, besides gold it is the only colored metal.
The development of copper based alloys has increased the use for the metal. Some alloys include: brass (copper and zinc), bronze (copper and tin), aluminum brass and bronze (aluminum and copper), silicon bronze (silicon and copper) and cupro nickel (nickel and copper).
Copper is an excellent electrical and thermal conductor, it is non-magnetic, corrosion resistant, anti-bacterial, easy to alloy, easily joined, recyclable, ductile and catalytic.
Due to its resistance to corrosion and high heat conductivity, copper is commonly used in the electrical, plumbing and chemical industries.
