Copper Bar & Profile
C21000/H96 Brass Bar
C10200/TU1 Copper Bar is bar stock made from Oxygen-Free Copper (OFC) (purity ≥99.95% Cu). Its very low oxygen content provides very high electrical and thermal conductivity (≥99.8% IACS) and, critically, immunity to hydrogen embrittlement. This makes it superior to ETP (C11000) for components that require welding or brazing. C10200 bar is extensively used in electrical systems for bus conductors, power transmission components, and high-quality electronic parts, as well as in vacuum systems and heat exchangers where its excellent weldability, purity, and conductivity are required.
