Background

It is believed that copper has been mined for over 5000 years. It can be found in elemental form and in the minerals cuprite, malachite, azurite, chalcopyrite and bornite. Copper is also often found as a by-product of silver production.

Basic Copper Properties

Next to silver, copper is the next best conductor. It is a yellowish red metal that polishes to a bright metallic lustre. It is tough, ductile and malleable. Copper has a disagreeable taste and a peculiar smell.

Copper is resistant to corrosion in most atmospheres including marine and industrial environments. It is corroded by oxidising acids, halogens, sulphides and ammonia based solutions.

Alloy C106

Copper alloy C106 is phosphorous de-oxidised non-arsenical copper that is 99.85% pure.
