What is Copper?

Copper is a ductile, malleable transition metal with excellent electrical and thermal conductivity. One of the few naturally occurring metallic elements, copper has been used by humans for over 10,000 years. The Bronze Age was defined by its alloys. It has distinctive reddish-orange colour.

Formula & Notation

Cu

Properties & Characteristics

Appearance: lustrous reddish-orange metal. Melting point: 1084.62 °C. Boiling point: 2562 °C. Density: 8.96 g/cm³. Electrical conductivity: 5.96×10⁷ S/m (second only to silver). Thermal conductivity: 401 W/(m·K).

Uses & Applications

Electrical wiring (largest use). Plumbing and heat exchangers. Alloys: brass (Cu-Zn), bronze (Cu-Sn). Electronics and PCBs. Coins. Fungicide (copper sulfate). Essential trace nutrient in biology.

Safety Information

Essential trace mineral — deficiency causes health problems. Excessive intake is toxic; causes gastrointestinal disturbance and, in chronic overexposure, liver damage (Wilson disease susceptibility). Copper dust is a mild irritant.
