- Surface finishes include polished, mill-finished, or specialized coatings (e.g., tin-plated) .
International Standards
C10200 wire complies with globally recognized standards for quality and dimensional consistency:
Key Standards:
- ASTM B187/B187M: Specifies requirements for rectangular/square bare copper conductors .
- ASTM B152: Covers flat-rolled products (sheets, strips) .
- IEC 60317-13: Applies to enameled round copper wire for windings (Class 200) .
Main ingredients:
Copper (Cu) content: ≥99.95% (oxygen-free copper No. 2) to ≥99.97% (oxygen-free copper No. 1), total impurity content ≤0.03%-0.05%.
Oxygen (O) content: generally ≤0.003% (30 ppm), ≤0.001% (such as vacuum application scenarios).
Impurity restrictions:
Lead (Pb) ≤0.004%, iron (Fe) ≤0.004%, sulfur (S) ≤0.004%, zinc (Zn) ≤0.003%, others such as bismuth (Bi), antimony (Sb), arsenic (As), nickel (Ni), etc. are all subject to restrictions.

Production process and product advantages of C10200 copper wire:
1. Production process
The production process of C10200 copper wire mainly includes the following steps:
Smelting: Melt pure copper (purity ≥ 99.9%) at high temperature, and strictly control the oxygen content (≤ 0.001%) to reduce the risk of hydrogen embrittlement.
Casting: Use continuous casting, sand casting and other methods to form ingots or castings to ensure material uniformity.
Heat treatment: Adjust the organizational properties through annealing (temperature 375-650℃) to improve ductility and conductivity.
Processing and forming: The ingot is processed into wire through cold/hot processing (such as drawing and rolling), supporting the production of ultra-fine copper wire as thin as 0.01mm. Oxidation pollution should be avoided during processing to maintain high purity.
2. Product advantages
High conductivity and thermal conductivity
The conductivity reaches 100% IACS (International Annealed Copper Standard), and the thermal conductivity is excellent, which is suitable for high-power current transmission and high-precision electrical components.
Low oxygen content (≤0.001%) reduces the risk of hydrogen embrittlement and ensures long-term stability.
Excellent processing performance
Excellent plasticity, supports cold/hot forming, forging, stamping and other processes, can be made into ultra-fine wires (0.01mm), special-shaped wires and complex parts.
Excellent welding performance, suitable for TIG welding, MIG welding and other methods, high joint strength and good air tightness.
Corrosion resistance and anti-magnetism
Strong corrosion resistance to atmosphere, water and various media, surface oxide film (patina) provides additional protection.
Anti-magnetic properties are suitable for precision instruments (such as compasses, magnetrons).
Wide range of applications
Electrical and electronic: wires, cables, brushes, connectors, semiconductor parts, etc.
High-end manufacturing: new energy vehicle connectors, microwave tubes, vacuum coating equipment, waveguide components, etc.
Industrial fields: heat exchangers, seawater pipeline systems, oil and gas equipment.
Standardization and reliability
Complies with international standards such as ASTM B187/B187M, EN 13602, etc. to ensure material consistency and traceability.
