16 Characteristics of Copper - Simplicable

Copper is a soft metal that is malleable such that it can be easily hammered into a thin sheet without breaking. It is also ductile such that it can be stretched to create long things such as a wire. The softness of copper meant that copper age societies had relatively weak tools and weapons as compared to bronze age or iron age societies.

Properties of Copper - Matmatch

Pure copper has an electrical conductivity value of 5.9×10 7 Siemens/m, making it the second most electrically conductive metal to silver, which has a value of 6.2x10 7 Siemens/m. As copper is far more abundant and therefore less expensive than silver, copper quickly became a popular method for transmitting electricity.
