Oxygen Free Copper

Oxygen Free Copper (OFC) is a copper alloy that has been electrolytically refined in order to decrease the oxygen levels present to less than .001%. As a result, Oxygen Free Copper is highly conductive, and is also often known as Oxygen-Free High Thermal Conductivity (OFHC). Oxygen-Free Copper is mainly used in applications requiring high conductivity and exceptional ductility.

As well as ensuring high levels of electrical conductivity, more than any other grade of commercial copper, this oxygen free material also gives improved qualities for formability and joining. Oxygen free copper can be used for vacuum engineering, transformers & motors, generators, switchgears, electrical instruments.

Copper was one of the first metals that was ever used by humans, and since its discovery in approximately 8000 B.C. we have found many innovative and useful ways to utilise copper metal.

Copper’s main properties and qualities include great ductility, excellent conductor of electricity and heat; it is also a malleable metal. Due to these characteristics, copper is often used in electrical components such as motors, wiring, machinery heat exchangers and electronic connecters.

Copper is also one of the primary metals used to make cooking utensils and equipment, but the copper that we probably have the most daily contact with - coins.

The density of copper in its purest form is 8.92 gm/cm3.

An easy way to determine if your copper is pure via density is to use the following method:

  • Measure the weight of your copper

  • Measure the dimensions of your copper to discover the volume (volume = L x W x H)

  • Divide the weight of your copper by the volume

  • Compare your results with the density of pure copper : 8.92 gm/cm3

If your result isn’t the same as above, this might mean your copper is not pure or that your measurements are not accurate.


Copper is a versatile method with a wide-ranging portfolio of properties that makes it the ideal metal to use in a variety of applications. Some of the most useful properties of copper are:

  • Good Electrical Conductivity

  • Good Thermal Conductivity

  • Corrosion Resistant

  • Ductile and Malleable

  • Easy to Alloy

  • Anti-Bacterial

  • Non-Magnetic
