Product Overview

C10200 copper, commonly referred to as Oxygen-Free (OF) copper, is a high-purity copper grade containing a minimum of 99.95% copper with very low oxygen content. It is manufactured to ASTM B170 standards and offers excellent electrical and thermal conductivity for industrial applications.

Produced through controlled refining processes, C10200 copper provides good ductility, reliable formability, and improved resistance to hydrogen embrittlement compared to standard copper grades. Its conductivity ranges between 100–101% IACS, making it suitable for high-performance electrical components.

C10200 copper is widely used in electrical equipment, bus bars, and heat transfer systems where consistent conductivity and material stability are required. It is commonly applied across power generation, electronics, and general engineering industries.

C10200 Oxygen-Free Copper (OF) — FAQ

Practical FAQ on C10200 OF copper, ASTM specs, properties and how it compares with OFE and ETP copper.

C10200 is oxygen-free copper with Cu+Ag ≥99.95% and oxygen <10 ppm. It offers near-pure conductivity without the hydrogen-embrittlement risk of oxygen-bearing ETP copper.
ASTM B152 (sheet/strip/plate) and B187 (rod/bar) cover C10200; it is supplied as sheet, strip, rod and bar.
Conductivity is about 100% IACS, with annealed UTS ~200–250 MPa and elongation ~40%. Like C10100 it is not heat-treatable and is joined by brazing or soldering rather than gas welding.
C10100 (OFE) is the purest (≥99.99%, <5 ppm O) and highest conductivity; C10200 (OF) is ≥99.95% with <10 ppm O; C11000 (ETP) is oxygen-bearing (~100% IACS) and cheaper but susceptible to hydrogen embrittlement. Choose OF/OFE when hydrogen exposure or maximum conductivity is a concern.
Linsy supplies C10200 to ASTM with an MTR/MTC, SGS on request, and RoHS/REACH support. Typical lead time is 10–60 days with low MOQ and a 1-hour quoting response.
