Product Description
High-Precision Copper Foil is a critical component in modern manufacturing, celebrated for its exceptional conductivity, flexibility, and reliability. Sourced from top-grade copper alloys including C10100, C1100, C1020, T2, Cu-ETP, and CW004A, this copper foil meets stringent international standards such as GB/T 2529-2012, ASTM 187M, JIS, and ROHS, ensuring uncompromised quality for diverse applications. With a thickness range of 0.0060.09mm and width options from 100650mm, the precision copper foil caters to the needs of electronics, automotive, energy, and telecommunications industries, where performance and consistency are paramount. As a trusted supplier of high-quality copper foil, we prioritize strict quality control, competitive pricing, and customer-centric service, offering a minimum order quantity (MOQ) of 200 KGS to accommodate both small-batch prototypes and large-scale production runs. Whether for printed circuit boards (PCBs), lithium-ion batteries, or electromagnetic shielding, this copper foil delivers superior performance that drives innovation in modern technology.
The High-Precision Copper Foil is crafted from premium copper alloys, including C1100 copper foil (oxygen-free high-conductivity copper) and T2 copper foil, known for their exceptional electrical and thermal conductivity. These alloys minimize resistance, ensuring efficient energy transfer and heat dissipation—critical for high-performance electronic devices. Additionally, the alloys offer excellent corrosion resistance and ductility, allowing the copper foil to withstand harsh manufacturing processes such as etching, laminating, and bending without compromising structural integrity.
With a thickness range of 0.006~0.09mm, this precision copper foil achieves ultra-thin dimensions while maintaining exceptional dimensional stability. The tight thickness tolerance ensures uniform performance across the entire foil surface, making it ideal for applications requiring precise spacing and alignment, such as microelectronic components and flexible PCBs. The width range of 100~650mm provides flexibility for both small-scale projects and large-panel manufacturing, reducing material waste and optimizing production efficiency.
Every roll of High-Precision Copper Foil adheres to strict international standards, including GB/T 2529-2012, ASTM 187M, JIS, and ROHS. These standards govern material purity, dimensional accuracy, surface finish, and environmental safety, ensuring the copper foil is free from harmful substances and meets the requirements of regulated industries. Compliance with ROHS makes it suitable for use in eco-friendly products, while adherence to ASTM and JIS standards ensures compatibility with global manufacturing processes.
The high-quality copper foil features a smooth, clean surface with minimal defects such as pinholes, scratches, or oxidation. This superior surface quality is achieved through advanced rolling and annealing processes, ensuring excellent adhesion to substrates (such as epoxy resins and polyimides) in PCB manufacturing. Consistent surface properties across batches reduce production variability, improving yield rates and reducing costs for manufacturers. Whether used in high-frequency circuits or battery electrodes, the copper foil delivers reliable performance with every roll.
High-Precision Copper Foil is a cornerstone of PCB manufacturing, used as conductive layers in rigid, flexible, and rigid-flex PCBs. Its exceptional electrical conductivity ensures efficient signal transmission, while its thin profile allows for high-density component placement—critical for compact electronic devices such as smartphones, laptops, and wearables. The foil’s ductility enables it to withstand the bending and folding required for flexible PCBs, making it ideal for portable and curved electronics.
In the energy storage sector, this copper foil serves as a current collector in lithium-ion batteries, used in electric vehicles (EVs), smartphones, and renewable energy systems. Its high conductivity facilitates fast charging and discharging, while its corrosion resistance ensures long battery life. The ultra-thin thickness of the foil reduces battery weight and volume, improving energy density and overall performance.
Precision copper foil is widely used for electromagnetic interference (EMI) shielding in electronic devices, medical equipment, and telecommunications infrastructure. Its high conductivity creates a barrier that blocks unwanted electromagnetic signals, preventing interference between components and ensuring device reliability. The foil can be easily laminated onto plastics, metals, or fabrics, making it suitable for a range of shielding applications, from consumer electronics to military equipment.
Due to its excellent thermal conductivity, the copper foil is used in thermal management systems, such as heat sinks for CPUs, power amplifiers, and LED lighting. It efficiently dissipates heat away from sensitive components, preventing overheating and extending device lifespan. The thin and flexible nature of the foil allows for custom shaping to fit complex heat sink designs, optimizing thermal performance in tight spaces.

We understand that different applications require unique specifications, which is why we offer customized copper foil solutions. Clients can select from a range of alloy options (including C1100, T2, and Cu-ETP) and specify custom thicknesses (within 0.0060.09mm) and widths (within 100650mm) to meet their exact needs. Our production team works closely with clients to ensure dimensional accuracy and alloy compatibility, providing technical support to optimize the product for specific applications.
With a minimum order quantity of 200 KGS, we cater to both small-batch orders (such as prototypes and sample production) and large-scale manufacturing runs. For bulk orders, we offer competitive pricing and flexible delivery schedules to align with production timelines. Packaging is designed to protect the high-precision copper foil during shipping, with options for vacuum-sealed rolls, moisture-resistant wrapping, and custom labeling for easy inventory management.
Every roll of High-Precision Copper Foil undergoes rigorous quality inspection, including thickness measurement, surface defect checks, and conductivity testing, to ensure compliance with international standards. We provide detailed quality reports upon request, giving clients full transparency into product performance. Our technical team is also available to offer guidance on foil selection, processing methods (such as etching and laminating), and troubleshooting, helping clients achieve optimal results in their applications.
C1100 copper foil and T2 copper foil are preferred for high-precision applications due to their exceptional electrical conductivity (≥98% IACS) and thermal conductivity. C1100 is an oxygen-free high-conductivity (OFHC) copper, offering minimal impurities and maximum conductivity, while T2 copper provides a balance of conductivity, ductility, and cost-effectiveness. Both alloys resist corrosion and are easy to process, making them suitable for demanding applications such as PCBs and lithium-ion batteries.
While our standard thickness range is 0.0060.09mm and width range is 100650mm, we offer limited customization for special projects.
