Copper has been used by humans for over 10,000 years, making it one of the first metals ever discovered. The Copper Age (Chalcolithic Age) marked an important stage in human civilization before the Bronze Age.
Copper occurs naturally in native metallic form as well as in minerals such as chalcopyrite, malachite, bornite and cuprite. Large deposits are mined worldwide.

Copper is widely used in electrical wiring, electronics, motors, generators, transformers, plumbing systems, renewable energy technologies and coins.
Tin, Zinc, Silver, Gold and Nickel
Copper slowly reacts with oxygen and moisture to form a green protective layer called patina. It also reacts with strong oxidizing acids.
Electronic Configuration: [Ar] 3d¹⁰ 4s¹
Copper possesses outstanding electrical conductivity, thermal conductivity and corrosion resistance, making it indispensable for modern technology.
Only silver conducts electricity better than copper, but copper is far more abundant and economical, making it the world's preferred electrical conductor.
Nearly every home, factory and power station relies on copper wiring because of its excellent electrical conductivity and long-term reliability.
Copper forms the electrical pathways inside smartphones, computers, televisions, communication equipment and almost every electronic device.
Electric vehicles contain two to four times more copper than conventional vehicles. Copper is used in motors, batteries, charging systems and power cables.
Copper is used for plumbing, roofing, heat exchangers and architectural decoration because it resists corrosion and has a long service life.
Copper surfaces naturally destroy many bacteria and viruses. Hospitals often use copper alloys on door handles, bed rails and frequently touched surfaces to help reduce the spread of infections.
Copper forms two of history's most important alloys. Bronze (copper + tin) gave rise to the Bronze Age, while brass (copper + zinc) is widely used in musical instruments, plumbing fittings and decorative objects.
Scientists are improving copper alloys for electric vehicles, renewable energy systems, superconductors, advanced electronics and sustainable power transmission.
Copper is created inside massive stars through stellar nucleosynthesis and is released into space during supernova explosions, eventually becoming part of planets and living systems.
The chemical symbol Cu comes from the Latin word Cuprum, named after the island of Cyprus, which was famous for copper mining in ancient times.
