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.
Next to Silver, Copper is the next best conductor of electricity. It has yellow/gold colour that can be polished 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.
Copper Sheet suplied by us is Grade C101 0.3mm thickness & Grade C106 0.5mm, 0.7mm, 0.9mm, 1.2mm, 1.5mm, 2mm thickness.
C101/CW004A is the designation for the 99.9% pure copper used in a range of engineering applications.
C101/CW004A is also known as HC or high conductivity copper. It has a nominal conductivity of 100% IACS (International Annealed Copper Standard). It also has high thermal conductivity. This is therefore the material of choice for use in conductors and electrical components but not when the service environment is a reducing atmosphere.
High ductility and impact strength also serve to make C101/CW004A an extremely useful material.
C101/CW004A is also the base material from which common brasses and bronzes are produced.
Applications – C101/CW004A is typically used in:
~ General engineering
~ Domestic Appliances
~ Cold formed components
C106 / CW024A is phosphorous de-oxidised non-arsenical copper that is 99.9% pure.
C106 is typically used in applications like:
~ Gutters and roofing
~ Gas plants
~ Hydraulic, air and oil lines
~ Air Conditioning and refrigeration
~ Heater units and burners tubes Consumer
~ Plumbing pipe and fittings
