Copper – Commercial Metal Exchange

History of Copper

The history of copper dates back to ancient civilizations and is closely tied to the development of human technology. Early copper working processes included coldworking, annealing, smelting, and lost-wax casting. Humans first discovered copper and later its alloy, bronze, around 5500 BC in the Balkans. Approximately 2000 years later, people began alloying copper themselves, marking the start of the Bronze Age. Brass, a copper and zinc alloy, was discovered much later during the Greek period and favored by the Romans for its beauty and corrosion resistance.

Ancient societies across present-day Iran, Turkey, Israel, Egypt, India, Greece, and Rome utilized copper and its alloys for various items like coins, weapons, jewelry, and architecture. The Egyptians were particularly prolific, crafting tools, household items, and even makeup from copper. Despite the discovery of iron and subsequent eras, copper remained significant, with major mining operations like the Falun Mine in Sweden starting around 1000 AD and greatly contributing to European copper supply through the 1600s.

The 1700s saw copper used extensively in European shipbuilding to prevent biofouling of hulls, and by the 1800s, advancements like powder metallurgy and electroplating emerged, enabling new manufacturing techniques. In 1949, the Finnish company Outokumpu revolutionized copper smelting with the energy-efficient flash smelting process, lowering costs and environmental impact. Recognizing copper’s essential role in human health, the EPA set limits on copper levels in drinking water in 1991. Today, copper’s uses continue to expand, especially in telecommunications, electronics, renewable energy, and advanced manufacturing, due to its superconductivity, affordability, and non-sparking nature.
