C10200 Copper Strip is a high-purity oxygen-free copper material known for its exceptional electrical conductivity, thermal conductivity, and material stability. Its extremely low oxygen content makes it suitable for demanding applications requiring reliable performance and high material purity.
Widely used in precision electronics, semiconductor equipment, electrical components, and industrial applications where conductivity, consistency, and processing reliability are critical.
C10200 copper strip (also referred to as OFC copper strip, Oxygen-Free Copper C10200 coil, or CDA 102 precision strip) is a premium ultra-pure oxygen-free copper profile manufactured for high-frequency electronics, precision electrical components, and heat dissipation assemblies. Containing a minimum copper purity of 99.95% with an extremely low oxygen content (less than 0.001%), C10200 copper strips deliver outstanding electrical conductivity, exceptional thermal transfer, and excellent hydrogen embrittlement resistance.
At XQJ Metal, we manufacture high-precision C10200 copper strips in thin gauges, foil tempers, and heavy-duty coil rolls. Produced in strict compliance with ASTM B152, ASTM B272, and EN 1652 standards, our oxygen-free copper strip coils undergo continuous bright annealing to ensure smooth surface finish, tight dimensional tolerances, and uniform mechanical properties.

Q1: What is the main difference between C10200 and C11000 copper strips?
A: C10200 is oxygen-free copper (OFC) with less than 0.001% oxygen, making it highly resistant to hydrogen embrittlement during high-temperature brazing or welding. C11000 is electrolytic tough pitch (ETP) copper with small amounts of oxygen, suitable for standard electrical windings but vulnerable to embrittlement in hydrogen environments.
Q2: What precision slitting tolerances can you provide for thin C10200 copper strips?
A: We offer precision continuous coil slitting with width tolerances as tight as ±0.05mm and thickness tolerances within ±0.005mm depending on the gauge.
Q3: What is your Minimum Order Quantity (MOQ) for custom slit C10200 copper coils?
A: Our standard MOQ for custom slit strip dimensions is 200 kg. Standard stock widths can be dispatched in smaller sample quantities immediately.
