C1020 (OFC Oxygen-Free Copper) - UNS C10200 Description:

C1020 is high-purity oxygen-free copper (OFC) with a copper content of over 99.90%.

It is called Oxygen-Free Copper because it contains extremely low oxygen and no copper oxide (CuO) or residual deoxidizing agents.

This results in excellent electrical and thermal conductivity and prevents hydrogen embrittlement, even when heated in reducing atmospheres.

It is widely used in electrical components, heat transfer systems, and precision industrial applications requiring high conductivity and reliability.

Exceptional Purity and Conductivity

C1020 Oxygen-Free Copper boasts a copper content of Cu99.90, ensuring minimal oxygen and impurity levels. This results in superior electrical and thermal conductivity, making it ideal for advanced electronic and electrical installations. Its pristine quality meets the highest industry standards.

Versatile Forms and Grades

Supplied as both coils and sheets, C1020 is available in a range of tempers-annealed (O) and as-rolled (1/4 hard, 1/2 hard, hard)-allowing for flexibility in manufacturing and engineering. Custom dimensions (width and thickness) are available upon request to suit specific project needs.

Trusted Japanese Manufacturing

As a leading exporter, manufacturer, and supplier in Japan, our C1020 copper products maintain strict quality control throughout production. Customers rely on our expertise and tailored solutions for their specialized copper requirements worldwide.

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.
