Copper foil sheets or strips with thicknesses ranging from 0.01mm to 3.0mm are available in various materials and applications. These foils are commonly used in electronics, industrial, and decorative fields due to their excellent electrical and thermal conductivity, flexibility, and corrosion resistance. They can be customized in width and thickness to meet specific project requirements.
Key Characteristics and Applications:
Thickness Range:
The 0.01mm to 3.0mm range covers a broad spectrum of applications, from extremely thin foils for sensitive electronics to thicker strips for structural or heat transfer purposes.
Material Purity:
Copper foil is often available in high purity (e.g., 99.97% or 99.99%) for applications requiring optimal conductivity.
Conductivity:
Copper is a highly conductive material, making it suitable for electrical and thermal applications.
Flexibility and Formability:
Thin copper foils are flexible and can be easily bent, shaped, or cut to fit specific designs or components.
Corrosion Resistance:
Copper naturally develops a protective patina, enhancing its resistance to corrosion.
Customization:
Many suppliers offer custom widths and thicknesses to match specific project needs.
Common Applications:
Electronics: Wiring, circuit boards, electromagnetic shielding, conductive components.
Industrial: Heat exchangers, radiators, corrosion-resistant equipment, and pipelines.
Decorative: Architectural elements, art pieces.
Automotive: Wiring, connectors, and sensors.
Considerations when choosing copper foil:
Thickness: Choose the appropriate thickness based on the application's requirements for conductivity, flexibility, and mechanical strength.
Purity: Higher purity copper offers better conductivity.
Customization: If standard sizes don't fit, consider custom-width and thickness options.
Supplier Reputation: Look for reputable suppliers with experience in providing quality copper foil.
