Thickness range:

Copper strip: minimum thickness is 0.01 mm (high-precision strip), conventional thickness is 0.075–5.00 mm, and some standards cover up to 25 mm (such as EN 13599).

Copper strip width is usually 8–1250 mm, and high-precision strip width can be customized to 600 mm (tolerance ±0.1 mm).

Other parameters:

Inner diameter of copper strip coil: 80–500 mm, unit weight is 3–14 kg/mm (adjusted according to thickness and width).

Tolerance requirements: Thin strips (such as 0.01–0.1 mm) have a thickness tolerance of ±0.02 mm and a width tolerance of ±0.1 mm; thicker strips (such as above 0.5 mm) have looser tolerances.

International Standards

European Standards:

EN 13599: Copper plates, sheets and strips for electrical purposes, with a thickness of 0.05–25 mm and a width of 10–1250 mm, covering chemical composition, electrical conductivity (≥58 MS/m) and mechanical properties.

EN 1652: General copper plate and strip standard, suitable for non-electrical fields.

American Standards:

ASTM B152: Specifies the chemical composition, tensile strength (≥195 MPa), elongation (≥30%), etc. of copper strips, with a thickness range of 0.5–0.8 mm (adjusted according to the application).

Chinese Standards:

GB/T 2059: Cold-rolled copper strip standard, with a thickness of 0.05–3.0 mm, width determined by the buyer, and electrical conductivity requirements (such as T2 pure copper ≥98% IACS).

GB/T 5231-2022: specifies the chemical composition (Cu 79.0–81.0%, balance Zn) and processing requirements of C24000.

Other standards:

JIS H3100 (Japan): corresponds to C24000 copper strip, thickness and tolerance are similar to GB/T.

BS EN 13599 (UK): consistent with European standards, emphasizing electrical performance verification methods.
