Description du produit
Our C11000 Pure Copper Foil is manufactured for applications requiring high electrical conductivity, superior ductility, and precise dimensional control. With a copper purity of 99.9% minimum, this copper strip is ideal for printed circuit boards (PCBs), electrical components, busbars, and grounding systems.
We offer direct factory supply with customizable thickness (0.05–0.15mm), width (≤600mm), and length (as required). Multiple tempers are available – from annealed (soft) to full hard – allowing you to match the material to your specific forming or stamping process.
All products comply with GB/T467-2010 and are manufactured under ISO9001, ISO14001, and ISO45001 certified processes.

-
Etched copper traces for single-sided, double-sided, and multilayer PCBs
-
High-purity requirement for signal integrity
-
Busbars, switchgear, transformer windings, and grounding strips
-
High current-carrying capacity with low resistive loss
-
Roofing, flashing, and architectural cladding
-
Polished finish available for visible applications
-
Terminals, connectors, shielding cans, and gaskets
-
Multiple tempers allow precise spring or soft-forming behavior
-
Solar panel interconnects, battery tabs, and inverter busbars
-
EV charging components
-
Lamination – The copper foil is bonded onto a dielectric substrate (e.g., epoxy resin, FR-4) using heat and pressure.
-
Etching – Unwanted copper is chemically removed, leaving the desired circuit pattern.
-
Conduction – Due to ≥99.9% purity, the remaining copper traces carry electrical signals with minimal resistive loss.
-
High conductivity (≥97% IACS) ensures efficient power transfer.
-
Proper temper selection allows bending or punching without cracking.
-
Rolled grain structure improves mechanical strength in hard tempers.
The combination of purity, flatness, and controlled temper makes C11000 copper the first choice for mission‑critical current‑carrying parts.
A: Yes – for standard PCBs and many high-frequency designs, C11000 with ≥99.9% purity performs well. However, for millimeter-wave or ultra-low-loss 5G applications, we recommend discussing VLP or HVLP treated foils separately.
A: This product line focuses on ≤600mm for precision slitting and stamping. For wider rolls (e.g., 1270mm), please contact us – we have other production lines available.
A:
-
Annealed (soft) – Excellent for deep drawing, bending, and etching.
-
Hard – Higher tensile strength; holds shape better after stamping or forming.
A: Yes – trial samples (A4 size or small rolls) are available upon request. The 1-ton MOQ applies to formal production orders.
A: A polished or standard rolled finish works well. For improved adhesion to resin, we recommend a customized surface treatment (please inquire).
A: Standard export package – moisture-proof paper, plastic-lined wooden pallets, and edge protectors to prevent damage during shipping.
A: 15–25 days after order confirmation, depending on quantity and temper/surface requirements.
A: Yes, we accept L/C at sight, T/T advance, or negotiable terms for long-term contracts.
