Copper is currently traded partially in smelted bar form; however this was not always the case. Copper is one of the oldest metals used by man. Its use dates back more than ten thousand years to the time of the Hittites during the bronze age. For almost 5,000 years copper was the only metal used, and it was used in the pure raw form and was hammered out into first decorative, then utilitarian items. Copper was a signature of wealth. Gold did not appear in history till roughly 5000 years after copper, and even then copper was the more valuable metal for the next 1,000 years.
Because of its reasonable malleability, very early in civilization copper was used to make coins. The Roman empire made copper coins of varying value, and copper, because of it’s beauty and durability is still used today in making coins, such as the penny.
Today copper bar and copper busbar are mostly traded in bar form and is used extensively in industry as electrical conductors although again because of the beauty and durability of the metal more and more usage is being seen in architecture. The statue of liberty is a good example.
Copper Bar and Copper Busbar offer very high electrical conductivity ratings, good resistance against fire and it is very resistant to melting down from intense heat of high electrical resistance. It is also utilized in production of bus stations, circuit breakers, furnace, switchgear, voltage regulation, high voltage power stations, computers, transformers, power packs, switching stations, voltage regulation, jet, train, truck, railroad power systems, along with furnace, plating rack, missile and high voltage applications. Copper bar is also utilized in copper bus boards, circuit boards, switchboards, generators, plating racks and high voltage electrical applications as busbar. So now you have a bit of the history and usage of copper bar and copper busbar.
