Frequently Asked Questions (FAQ)
1. What is C10100 TU2 copper square bar?
C10100 TU2 Copper Square Bar refers to oxygen-free copper square stock used in electrical and precision engineering applications. UNS C10100 is an oxygen-free electronic (OFE) copper grade, while TU2 is a Chinese oxygen-free copper designation. Both are associated with high electrical conductivity and low oxygen content, but their chemical composition and technical requirements should be verified against the applicable material standards.
2. What is the difference between C10100 and C11000 copper square bars?
C10100 is oxygen-free electronic copper, while C11000 is electrolytic tough pitch (ETP) copper. Both offer excellent electrical and thermal conductivity. C10100 is generally preferred for applications requiring very low oxygen content, such as selected vacuum and specialized electronic components. C11000 is commonly used for general electrical conductors, connectors, and busbar components. Final material selection depends on operating conditions, fabrication methods, and applicable specifications.
3. What standards apply to C10100 copper square bars?
ASTM B187/B187M covers copper bus bars, rods, and shapes for electrical applications and may be applicable to C10100 square bars when the specified product requirements are satisfied. TU2 copper products should be evaluated according to the relevant Chinese material and product standards. Buyers should confirm the required grade, temper, dimensions, tolerances, and inspection requirements before placing an order.
4. Can C10100 copper square bars be used in vacuum equipment?
Yes. C10100 oxygen-free copper can be used in selected vacuum equipment, electronic instruments, and specialized conductive assemblies. Its low oxygen content and high conductivity make it suitable for certain precision components. However, suitability for high-vacuum or ultra-high-vacuum systems also depends on material cleanliness, surface treatment, outgassing behavior, joining methods, and the equipment manufacturer’s specifications.
5. Can C10100 copper square bars be machined into precision components?
Yes. C10100 copper square bars can be cut, drilled, milled, and machined into electrical connectors, conductive blocks, heat transfer components, and precision equipment parts. Their square cross-section provides flat surfaces for clamping and accurate positioning. Because high-purity copper is ductile and may produce continuous chips, appropriate cutting tools, lubrication, and machining parameters are important for maintaining dimensional accuracy and surface quality.
