Copper is a semi-precious metal that occurs naturally in the form of copper ore and is mainly mined in Chile, the United States, and Peru. This reddish-brown material is considered one of the oldest metals in the world: together with gold, silver, and tin, it has been used for around 9,000 years. In ancient Egypt, copper pipes were already being used more than 5,000 years ago – many of them are still intact today. The Statue of Liberty in New York also contains around 80 tons of copper, an impressive example of its durability.
Applications and Properties
Copper is probably best known from the small 1, 2, and 5 cent coins. However, thanks to its outstanding electrical conductivity, it is primarily used in the electrical industry – for example in cables and wiring.
Because copper forms a natural patina when exposed to weather conditions, it is highly corrosion-resistant and is widely used in construction for pipes, façades, and roofing. Demand for copper has increased significantly in recent years because it not only conducts electricity efficiently but also transfers heat extremely well. This makes it ideal for renewable energy applications, such as solar systems.
Copper is a soft metal that can be processed and shaped very easily, even at low temperatures. It also has antibacterial properties and naturally changes appearance when exposed to air – developing its characteristic reddish-brown color over time. If this look is not desired, copper products from METALXACT can be individually powder coated to combine color, gloss, and protection perfectly.

Our Conclusion
Copper is not only a traditional material but also a future-oriented resource. It combines aesthetics, functionality, and sustainability – from historical buildings to modern solar systems. Thanks to its durability, formability, and natural protective layer, copper is suitable for both indoor and outdoor applications.
At a time when renewable energy is becoming increasingly important, copper will continue to play a crucial role in craftsmanship, industry, and sustainable energy supply.
