We are committed to providing excellent customer service and technical support to ensure customers’ success. Whether you need a small quantity or a large volume of oxygen Free Copper products, Om Steel can provide you with the right solution to meet your needs.

Properties of

Oxygen Free Copper

Check Icon

High Electrical Conductivity

OFC has a high electrical conductivity, with rating of at least 101% IACS (International Annealed Copper Standard). This means that it is an excellent conductor of electricity, with low resistance to the flow of electrical current.

Check Icon

Low Thermal Conductivity

While OFC is an excellent conductor of electricity, it has a relatively low thermal conductivity compared to other metals, such as aluminium or silver. This makes it less efficient at dissipating heat, which can be a disadvantage in some applications.

Check Icon

Good Ductility and Malleability

OFC is a very ductile and malleable material, which means that it can be easily formed and shaped without breaking or cracking. This makes it a good choice for applications where the material needs to be bent or formed into complex shapes.

Check Icon

High Corrosion Resistance

OFC is highly resistant to corrosion, making it a good choice for applications where the material will be exposed to moisture or other corrosive environments.

Check Icon

Low Magnetism

OFC is a non-magnetic material, which makes it a good choice for applications where magnetic interference could be a problem.
