OFHC Copper Bar

OFHC Copper Bar offers unmatched electrical and thermal conductivity, exceptional purity, and superior resistance to hydrogen embrittlement due to its oxygen content held below 0.001 %, making it ideal for demanding scientific and industrial roles. This ultra-high conductivity, often exceeding 101% of the International Annealed Copper Standard (IACS), enhances performance in applications requiring rapid heat transfer or high-current electrical conduction. Industries such as cryogenics, vacuum technology, power generation, and superconducting systems rely on OFHC copper bars for busbars, thermal blocks, and components in particle accelerators and MRI systems. Specific technologies that benefit include superconducting magnet supports, cryogenic thermal links, and precision vacuum chamber mounts. In research, these bars enable the development of high-vacuum equipment, low-temperature detectors, and advanced heat management prototypes. Their combination of ultra-purity, ductility, and exceptional conductivity ensures OFHC Copper Bars remain indispensable in both industrial and scientific contexts.
