Oxygen-free Copper tube applications:
On industrial applications, C10100 oxygen-free copper is valued more for its chemical purity than its electrical conductivity. OF/OFE-grade copper is used in plasma deposition (sputtering) processes, including the manufacture of semiconductors and superconductor components, as well as in other ultra-high vacuum devices such as particle accelerators. By the role of conveying current and connecting electrical equipment, Solar photovoltaic project construction, Substation project construction material. Superior Audio/Visual Applications, High vacuum applications,
Large industrial transformers – the increased electrical conductivity of Oxygen Free Copper can reduce the diameter of the wiring within transformers and therefore reduce the amount of copper and the size of the overall installation.
