A Basic Primer on Copper, the Red Metal

Strength: Copper is a weak metal with a tensile strength about half that of mild carbon steel. This explains why copper is easily formed by hand but is not a good choice for structural appliions. Toughness: Copper may not be strong, but it is not easy to break due to its high toughness. This property comes in handy for piping and tube appliions, where a rupture can be dangerous and

Copper properties and uses. Introduction.
