The directory lists C11000 (ETP copper), C10100 (OFHC copper), and C10200 (oxygen-free copper). C11000 is for general use; C10100 offers higher conductivity and ductility. Confirm availability and suitability with the supplier.
Standard widths range from 20 to 200 mm, thicknesses from 3 to 20 mm, and lengths from 1000 to 6000 mm. Tolerances are ±0.5 mm for width up to 100 mm and ±0.2 mm for thickness up to 10 mm. Custom sizes may be available; verify with the manufacturer.
Electrical conductivity is given as ≥100% IACS for C11000 and ≥101% IACS for C10100, per GB/T 5585.1. Test methods follow GB/T 3048.2. Always confirm actual values for the specific product.
Surface finishes include bare, tin-plated, or silver-plated. Plating thickness is per customer specification. These treatments enhance corrosion resistance and contact performance. Verify options with the supplier.
