Description


Copper and copper alloys are amongst the most necessary materials needed to provide the means to keep homes, commerce and industry running.

The main possible combinations of properties which are often unique to copper base alloys enable them to meet the challenges of modern life in many ways, making them suitable for applications in virtually every area of human activity.

Characteristics of Copper

  • Electrical conductivity
  • Corrosion resistance
  • Heat transfer
  • Structural capability
  • Aesthetic appeal

Common forms of copper include:

High conductivity (HC) electrolytically refined copper (sometimes known as a tough pitch copper or "electro"), with a nominal conductivity of 100% IACS (International Annealed Copper Standard), is used for most electrical applications such as busbars, cables and windings. High conductivity copper is very readily worked hot or cold. It has excellent ductility which means that it can be easily drawn to fine wire sizes and it is available in all fabricated forms.

Deoxidised copper (Usually deoxidised with phosphorus) is a material that can be readily brazed or welded without fear of embrittlement. It may be known colloquially as "Deox" and is used for the manufacture of tubing for fresh water and for hot water cylinders.

Oxygen free high conductivity copper (OFHC is a registered trade mark) is produced by casting in a controlled atmosphere and is used where freedom from the possibility of embrittlement is required.
