Product Description
Produced by hot rolling and cold rolling from high-purity copper or copper alloy ingot, then coiled into compact rolls. Features excellent electrical and thermal conductivity, good corrosion resistance, uniform thickness, and high formability. Available materials: pure copper (T2, TP2, C11000, C12200), brass (H62, H65, H68, H70, H85), bronze (QSn6.5-0.1, C51900). Thickness range: 0.1mm – 3.0mm (thin coil), hot rolled coil up to 12mm. Width: 100mm – 1500mm (slit or full width). Coil inner diameter: 300mm, 400mm, 500mm, or 508mm. Coil weight: custom, typically 1–8 tons. Surface finish: mill finish (as-rolled), cold rolled (bright), pickled, polished, or coated. Temper: soft (annealed), half hard, hard. Edge condition: mill edge or slit edge (deburred). Excellent formability for stamping, roll forming, and deep drawing. Meets ASTM B152, EN 1652, JIS H3100, or GB/T 2059 standards. Custom widths, coatings, and tempers available.

Application description:
Widely used in electrical and electronic industries (transformer windings, flexible busbars, cable shielding, flexible printed circuits), roofing and flashing (architectural copper), automotive heat exchangers (radiators, condensers), industrial gaskets, solar thermal collectors, and decorative trim. The coil form allows high-speed stamping, roll forming, and deep drawing for mass production. Pure copper coils offer excellent conductivity; brass coils provide strength and corrosion resistance for hardware and decorative applications.
Production description
Copper ingot is hot rolled to reduce thickness, then cold rolled to achieve precise gauge and surface finish. The strip is coiled, annealed to achieve desired temper, and optionally pickled, polished, or coated. The coil is slit to required width, inspected, and packed.
Shipping Packaging
For export, copper coils are wrapped with VCI paper and moisture-proof polyethylene, placed on ISPM-15 wooden pallets or steel skids, secured with steel straps, and fitted with edge protectors and coil protectors. Labels include grade, dimensions, coil weight, and heat number for safe sea freight.
Why Choose Us?
Factory Strength:Direct manufacturer with hot rolling and cold rolling mills, precision slitting lines, and annealing furnaces, producing copper coils in pure copper (T2, TP2, C11000, C12200), brass (H62–H85), and bronze (QSn6.5-0.1, C51900) with thickness 0.1–12mm, width up to 1500mm.
Quality Assurance:Strict control of chemical composition, electrical conductivity (≥97% IACS for pure copper), mechanical properties (tensile, yield, elongation, hardness), and thickness tolerance (±0.02mm); 100% eddy current or ultrasonic testing available; compliant with ASTM B152, EN 1652, JIS H3100, GB/T 2059.
Certifications & Reports:Mill test certificates (MTC) with each shipment; third-party inspections (SGS, BV) and test reports (conductivity, tensile, hardness, coating adhesion for coated coils) available upon request.
Customization & Service:Wide alloy range (pure copper, brass, bronze), thickness 0.1–12mm, custom widths (100–1500mm), coil weights (1–8 tons), tempers (soft, half hard, hard), surface finishes (mill, cold rolled, pickled, polished, coated), and fast lead times.
Export Packaging:VCI paper + moisture-proof polyethylene + ISPM-15 wooden pallets/steel skids + steel strapping + edge/coil protectors + clear labeling for safe sea freight and corrosion prevention.
