C1020 (OFC Oxygen-Free Copper) Description :

C1020 is pure Copper with a Copper content of over 99.96%.
It is also also called "Oxygen-Free Copper" (OFC) because it does not contain Copper Oxide (Cu₂O) or residual deoxidant.
It has excellent electrical and thermal conductivity and does not cause Hydrogen embrittlement even when heated to high temperatures in a reducing atmosphere.

FAQ's of C1020 (OFC Oxygen-Free Copper) - UNS C10200 | Pure Copper:

Q: How is C1020 (OFC Oxygen-Free Copper) commonly produced?

A: C1020 copper is manufactured using advanced refining and rolling processes to eliminate oxygen and minimize impurities, resulting in its characteristic high purity. The copper is then formed into coils or sheets and heat-treated to achieve the desired temper-either annealed or as-rolled.

Q: What advantages does using C1020 Oxygen-Free Copper offer over standard copper grades?

A: OFC C1020 delivers superior electrical and thermal conductivity, resistance to oxidation, and exceptional formability due to its high purity. These qualities make it preferable wherever critical performance and long-term reliability are required, such as in electronics, wiring, and specialized industrial uses.

Q: When should I choose the annealed versus as-rolled temper for my application?

A: Annealed (O) temper is ideal for applications needing enhanced flexibility and ease of forming, while as-rolled tempers (1/4H, 1/2H, H) provide increased strength and rigidity. Your choice depends on the specific mechanical and fabrication requirements of your project.

Q: Where can I order C1020 copper products with custom dimensions?

A: Our company provides C1020 copper coils and sheets with customizable width and thickness. Please contact us directly to discuss your sizing requirements and receive tailored solutions.

Q: What process ensures the high chemical purity (Cu99.90) of C1020 copper?

A: The oxygen-free process involves carefully controlled melting and casting methods that prevent oxygen absorption and contamination. Rigorous quality checks throughout production guarantee a copper content of at least 99.90%.

Q: How is C1020 typically used in electrical and electronic industries?

A: Due to its outstanding conductivity and reliability, C1020 is frequently employed for high-quality wiring, transformer and motor windings, semiconductor components, and other precision applications where electrical efficiency is paramount.
