Overview

Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C), with a valence of 1 or 2. Copper is reddish colored and takes a bright metallic luster. It is malleable, ductile, and a good conductor of electricity and heat. It is second only to silver as an electrical conductor. It is non magnetic and non-sparking. Copper is also anti-bacterial and corrosion resistant make it ideal for hospitals, food preparation, brewing and plumbing systems. Data provided by Copper.org.
