We offer a range of copper coil products that comply with international standards, covering various high-performance alloy grades including red copper coils (C11000), brass coils (C26000), phosphor bronze coils (C5191), and cupronickel coils (C70600). Our products are available in multiple thickness specifications and width options and support customized annealing states (soft/hard/half-hard) and surface treatment solutions (bright/anti-oxidation coating). Through precision rolling and atmosphere-controlled annealing processes, our copper coils maintain excellent electrical conductivity and ductility while delivering stable mechanical properties and resistance to environmental corrosion. They are widely used in electronic components, automotive cooling systems, precision connectors, and architectural decoration applications.

The production line employs a fully continuous rolling process, equipped with six-roll reversible cold rolling mills and vertical bright annealing furnaces. A tension closed-loop control system ensures stable control of coil flatness. The entire line integrates laser thickness gauges, surface defect detection systems, and online conductivity monitoring devices, combined with hydrogen-oxygen analyzers and micro-oxygen-controlled annealing technology to guarantee material performance compliance with international standards such as ASTM B370 and EN 1652. The production system is certified under the IATF 16949 automotive industry quality management standard and can provide customers with grain size inspection reports, bending test data, and full-process traceability documentation.

In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.

Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
