Product Detail1

Shanghai Metal Corporation is a leading Copper Tape/ Copper Strip / Copper Coil manufacturer and supplier.

Copper strip is a flat rolled product made of pure copper or copper alloy, produced by continuous rolling and slitting into defined width and thickness. It has excellent electrical conductivity, thermal conductivity and ductility, together with good corrosion resistance in atmospheric environments. It is used for electrical busbars, battery connectors, grounding components, heat dissipation parts, transformer windings and shielding materials. This material ensures stable electric current transmission, efficiently transfers heat, allows bending and stamping into complex shapes, and provides reliable shielding against electromagnetic interference for electronic and power systems.

1. Grade: C1100, C1020, C1220, etc.

2. Temper: O, 1/4H, 1/2H, 3/4H, H,SH,ESH.

3. Conductivity: ≥98% IACS.

4. Density: 8.9 g/cm³.

5. Thermal conductivity: 385 W/(m·K).

1.High Electrical Conductivity: Offers conductivity up to 98% IACS, supporting steady current transmission and lowering power loss for electrical and electronic assemblies.

2. Good Thermal Conductivity: Transfers heat efficiently across the material, helping dissipate heat quickly in heat sink components and prevent overheating of devices.

3. Superior Ductility & Formability: Can be bent, stamped and fabricated into complex shapes without cracking, enabling customers to produce customized connectors and shims.

4. Atmospheric Corrosion Resistance: Forms a stable passive oxide layer in normal air, slowing surface oxidation and extending service life for exposed grounding and busbar parts.

5. Excellent Electromagnetic Shielding Ability: Blocks electromagnetic wave penetration effectively, reducing signal interference in electronic modules and improving equipment stability.

1.Battery Connection Tabs: Used as conductive connectors between battery cells and busbars in lithium battery packs. Copper strip has high electrical conductivity to minimize power loss and good ductility for stamping into precise tab shapes.

2. Electrical Busbars: Fabricated into power distribution conductors inside switch cabinets and control panels. It carries large electric current steadily and can be bent to fit cabinet layout for compact power wiring.

3. Electromagnetic Shielding Gaskets: Made into shielding strips for electronic enclosures and communication devices. Copper strip blocks electromagnetic interference, preventing signal distortion between internal circuit components.

4. Heat Sink Spreader Sheets Applied as thermal transfer layers for power modules and LED assemblies. Its high thermal conductivity rapidly transfers heat away from heat-generating chips to lower operating temperature.

5. Grounding Conductors Installed as grounding strips in buildings and electrical equipment. Copper strip resists atmospheric corrosion and maintains stable low resistance, ensuring reliable fault current discharge for safety protection.

Production Process

Standard Packaging

Copper strips are wrapped with anti-tarnish paper to avoid oxidation and surface discoloration. Each coil is covered by PE plastic film, then placed on solid wooden pallets. Plastic straps fasten the whole pallet firmly. Edge guards protect strip edges from deformation. A printed label on each pallet marks alloy grade, temper, dimensions, net weight and batch number for traceability.

Shipping

We support FCL sea freight, LCL consolidated sea freight, air freight and international express delivery, according to total cargo weight, volume and receiving destination. Applicable trade terms include EXW, FOB, CIF. Other terms may be available upon request. Shipping cost is calculated based on gross weight, measurement volume, destination port and selected transport mode.

Lead Time

Standard stock orders:15‑25 working days

Custom thermal‑grade / custom dimension orders:30‑35 working days

Q1: What information do you need for a custom quotation for copper strip?
A: Please provide alloy grade, temper, thickness, width, surface finish, required quantity and cutting requirements.

Q2: What factors should I consider when selecting copper strip?
A: Consider required conductivity, forming demands, working environment corrosion level, dimensional tolerance and tensile strength.

Q3: Can copper strip be stamped, bent and welded for component fabrication?
A: Yes. Soft temper copper strip supports deep stamping and bending; all grades can be joined by soldering or resistance welding.

Q4: What is the typical IACS conductivity range for C1100 copper strip?
A: C1100 copper strip achieves minimum 98% IACS conductivity at room temperature.

Q5: How does temper affect the mechanical properties of copper strip?
A: O temper has high elongation for deep forming; H / SH temper has higher tensile strength but limited bending capability.

Q6: Will copper strip oxidize under normal indoor humid conditions?
A: Slow surface tarnish will occur. Anti-tarnish paper packaging can delay oxidation, but long-term damp exposure causes visible patina.
