For electrical, aerospace, and vacuum uses, our copper products are ASTM B187 and international standards compliant. With better pricing and better service, Luois Metals is your dependable solution for high-quality copper bar and rod solutions in challenging technical situations.
Copper C10200 is a high purity oxygen-free copper with at least 99.95% copper content and oxygen content less than 0.001%. It has superior electrical conductivity (≥101% IACS), superior thermal conductivity, and superior corrosion and hydrogen embrittlement resistance. Mechanical properties are tensile strength of approximately 220–260 MPa (annealed), elongation up to 45%, and Brinell hardness of 50–60 HB. It is in accordance with ASTM B187 and B170 standards. Its purity is high enough that it can be safely employed in applications sensitive to outgassing and oxide generation, like vacuum systems and cryogenic chambers.

Copper C10200 rods and bars are employed widely in electrical and electronic devices, such as conductors, switchgear, connectors, and high-performance cable. It is suitable for vacuum electronics, aerospace equipment, and semiconductor fabrication due to its high purity and low outgassing rate. C10200 is also chosen in RF and microwave because it has the least signal loss. The others include grounding systems, medical devices, and power generation facilities. It is also used in clean rooms and cryogenics because of its ultra-clean surface and thermal transfer capacity. This grade is best where non-negotiable reliability, conductivity, and corrosion resistance are necessary.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
