Frequently Asked Questions (FAQ)
1. What is C10200 TU2 copper square bar?
C10200 TU2 Copper Square Bar refers to solid square-section oxygen-free copper stock used in electrical and industrial applications. UNS C10200 is an oxygen-free copper grade known for excellent electrical and thermal conductivity. TU2 is a Chinese oxygen-free copper designation commonly compared with C10200. However, the two grades belong to different standards systems, and their equivalence should be verified against the applicable specifications and material test certificates.
2. What is the difference between C10200 and C10100 copper square bars?
C10200 is commonly designated Oxygen-Free (OF) Copper, while C10100 is designated Oxygen-Free Electronic (OFE) Copper. Both provide excellent electrical and thermal conductivity, but C10100 has more stringent composition requirements and is often specified for demanding electronic and specialized applications. C10200 is widely used for electrical connectors, conductive components, and industrial equipment. The appropriate grade should be selected according to the required material specification, manufacturing process, and operating conditions.
