Copper 101 Small Diameter Tubing

Copper 101 Small Diameter Tubing

High Conductivity, Precision Tubing Solutions from International Tube

At International Tube, we manufacture high-purity Copper 101 small diameter tubing—also known as Oxygen-Free Electronic (OFE) Copper, designated under UNS C10100. This material is prized for its exceptional electrical and thermal conductivity, making it an ideal choice for applications where signal integrity, heat transfer, and material cleanliness are critical.

Copper 101 is produced with a minimum copper content of 99.99% and is refined in an oxygen-free environment, resulting in ultra-low oxygen levels (<0.0005%). This ensures maximum conductivity and excellent resistance to hydrogen embrittlement and corrosion in reducing environments. Its outstanding purity and ductility make it particularly well-suited for precision forming and fabrication.

Copper 101 Tubing Features & Applications

Copper 101 tubing from International Tube is used in a wide range of industries where performance and precision are paramount. Key applications include:

• High-frequency electrical and RF systems

• Vacuum and electron tube systems

• Semiconductor and microelectronics manufacturing

• Scientific and laboratory instrumentation

• Medical device components

• Thermal management and heat exchangers

• Aerospace electrical and sensor assemblies

• Cryogenic and ultra-high vacuum (UHV) systems

Our small-diameter Copper 101 tubing is typically supplied in annealed or temper conditions based on application needs. Tubing is drawn from high-purity copper stock, formed to tight tolerances, and available in both straight lengths and continuous coil form. As with all International Tube products, our copper tubing is manufactured to deliver consistency, performance, and precision you can count on.
