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 produced as a by-product of
silver production.
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 corrosion-resistant to most
atmospheres including marine and
industrial environments. It is corroded
by oxidising acids, halogens, sulphides
and ammonia based solutions.
C106 / CW024A is phosphorous deoxidised
non-arsenical copper that is
99.9% pure.
