One reason copper is so widely used is because it can be recycled indefinitely without losing any of its chemical or physical properties. Recycled, or secondary, copper is indistinguishable from primary copper, and the production process consumes much less energy.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
