Copper Coil

Copper coils are coiled copper products made from copper and copper alloys (such as pure copper, brass, phosphor bronze, etc.) through continuous rolling processes including hot rolling, cold rolling, tension leveling and slitting. As one of the core base materials in the copper processing industry chain, they are widely used in industrial manufacturing, electronics, electrical engineering, architectural decoration and other fields. Classified by material, they include red copper coils, brass coils, phosphor bronze coils, etc.; classified by manufacturing process, they are divided into hot-rolled copper coils and cold-rolled copper coils. With a full range of specifications, their thickness, width and material can be customized on demand to ensure strong flexibility.
Copper coils inherit the core excellent properties of copper materials, featuring outstanding electrical conductivity, thermal conductivity and corrosion resistance, as well as good ductility and processability. Cold-rolled copper coils boast smooth surfaces and high dimensional accuracy, making them suitable for products with high appearance and precision requirements; hot-rolled copper coils have a wide thickness range and excellent toughness, ideal for rough processing scenarios such as structural parts and stamping components. Copper coils can be easily subjected to deep processing such as slitting, cutting to length, bending, stamping, welding, tin plating and electroplating, meeting diverse manufacturing needs.
With superior comprehensive performance, copper coils are extensively applied in electrical and electronic fields (leads, terminals, heat sinks, coils), refrigeration and air conditioning (refrigeration pipes, heat dissipation coiled tubes), hardware and sanitary ware (faucets, bathroom accessories), architectural decoration (decorative strips, curtain wall materials), petroleum and chemical industry (corrosion-resistant pipelines), automobile manufacturing (wiring harnesses, heat exchangers) and other industries. As core base materials for producing various copper parts, copper tubes and copper strips, they can also be used directly as coiled materials. With advantages of long service life, environmental protection and recyclability, stable performance, copper coils are indispensable key metal materials in modern industry and high-end manufacturing.
