Some of the most imporant physical properties of Copper are: 1. Although they exhibit orthorhombic symmetry, crystals, when found, are cubic, octahedral, or dodecahedral, often with curved or rough faces. Copper occurs in nature in the metallic state in certain locations such as in Lake Superior region but mostly as sulfide and to a minor extent as oxide and silicate. Properties of Copper The two main properties of copper that make it indispensable to mankind are its electrical and thermal conductivity but it’s the unique combination of these and other properties that make copper so versatile.
