Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. Copper is a ductile metal with an excellent thermal and electrical conductivity. It is rather supple in its pure state and, when fresh, has a pinkish or peachy color. It is an essential trace nutrient to all high plant and animal life. In animals, including humans, it is found primarily in the bloodstream, as a co-factor in various enzymes and in copper-based pigments.
