Properties of Oxygen Free Copper

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.

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.

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.

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.

Low Magnetism

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

FAQ

How is Oxygen Free Copper made?

Oxygen Free Copper (OFC) is made by melting and casting high-purity copper in a controlled environment that limits the exposure to oxygen. This process, known as “degassing,” involves bubbling argon or another inert gas through the molten copper to remove any remaining oxygen. After casting, the copper is then processed through a series of hot and cold rolling stages to produce the desired thickness and dimensions.

What is the price of Oxygen Free copper(OFC)?

The Price of Oxygen Free Copper is Rs 1500/kg*. Contact us to know more about Oxygen Free Copper.

What is the standard for oxygen free copper?

C101 Oxygen Free Copper is an exceptionally pure form of copper that contains minimal amounts of oxygen. Typically, it has an oxygen content of less than 0.0005% and a copper grade of 99.99%, making it the highest quality copper available. The material properties of C101 Oxygen Free Copper closely resemble those of elemental copper.

Is oxygen-free copper better than copper?

Pure copper contains a slightly lower copper content than oxygen-free copper, with a range of approximately 99.5% to 99.95%. Other impurities may be present, such as iron and oxygen. Pure copper boasts exceptional conductivity, thermal conductivity, and plasticity, and it can be easily pressed.
