Oxygen Free Copper Round Bar / OF Copper Rod C10100 3-100mm Diameter

C10100 Round Copper Bar

Alias: Oxygen Free Copper Round Bar / OF Copper Rod Standard: ASTM B152, ASTM B187, ASTM B49

Product Description

C10100 is oxygen-free high conductivity copper (OFHC), one of the purest copper grades with extremely low oxygen content. C10100 round copper bar has superior electrical and thermal conductivity, excellent ductility, good corrosion resistance and easy brazing / welding performance. It can be easily machined, forged and formed. This copper bar is widely used in electrical, electronic and thermal conductive industries where high conductivity is required.
