Products Description
Copper Foil Wire (ASTM B152 standard) refers to high-purity cold-rolled copper with a copper content of ≥99.9%, H65/H68 state (hardness optional), thickness 0.05-3mm, width ≤600mm (customizable).
International benchmarking: Conforms to IEC 60076, GB/T 5585 and other transformer material standards.
Core performance advantages
Conductivity: ≥100% IACS (International Annealed Copper Standard), measured resistivity 1.724×10⁻⁸Ω·m (silicon steel resistivity is about 4.6×10⁻⁷Ω·m, 28 times worse conductivity).
Current carrying capacity: 1mm² cross-sectional area can carry 10A current (JIS H3100 standard).
Tensile strength: hard state (H state) ≥350MPa, soft state (O state) ≥200MPa (ASTM B370).
Temperature resistance: long-term working temperature ≤150℃, short-term overload temperature resistance 300℃ (UL certification).
Corrosion resistance: salt spray test ≥48h without oxidation (ASTM B117 standard).
