Copper wire mesh is a versatile and high-performance metal mesh product crafted by our company, using high-purity copper wires (with a copper content of 99.9% or higher) through precise weaving processes. Celebrated for its exceptional electrical conductivity, thermal conductivity, corrosion resistance, and malleability, copper wire mesh has established itself as a go-to solution across a wide spectrum of industries, from electronics and construction to aerospace and artisanal applications. Its unique combination of properties makes it indispensable in scenarios where functionality, durability, and precision are paramount.
Material Characteristics
- Exceptional Electrical Conductivity: Copper is renowned as one of the best electrical conductors among common metals, second only to silver. This property makes copper wire mesh ideal for applications requiring efficient electrical transmission, such as electromagnetic shielding, grounding systems, and electrical filters. It effectively blocks or absorbs electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring the proper functioning of sensitive electronic equipment.
- Superior Thermal Conductivity: Alongside its electrical prowess, copper exhibits excellent thermal conductivity. This allows copper wire mesh to efficiently dissipate heat, making it suitable for use in heat exchangers, cooling systems, and thermal management components in electronics and industrial machinery. It helps maintain optimal operating temperatures, preventing overheating and extending the lifespan of equipment.
- Good Corrosion Resistance: While copper is not immune to corrosion, it forms a protective patina (a greenish layer) when exposed to air and moisture. This patina acts as a barrier, slowing down further corrosion and ensuring the mesh retains its structural integrity over time. It performs well in indoor environments, dry atmospheres, and mild industrial settings, though it may require additional protection in highly corrosive or marine environments.
- High Malleability and Ductility: Copper wires are highly malleable and ductile, allowing for intricate weaving patterns and easy shaping into various mesh sizes and forms. This flexibility enables the production of copper wire mesh with precise specifications, from ultra-fine meshes for filtration to coarse meshes for decorative purposes, without compromising its mechanical properties.
Structural Characteristics
- Uniform and Precise Mesh Construction: Our copper wire mesh is manufactured using advanced weaving techniques, ensuring consistent mesh size, uniform opening distribution, and reliable performance. The tightly interwoven copper wires create a stable structure that maintains its shape under normal mechanical stress, ensuring consistent filtration, shielding, or decorative effects.
- Versatile Weaving Patterns: We offer copper wire mesh in a variety of weaving patterns, including plain weave, twill weave, and Dutch weave, each designed to meet specific application needs. Plain weave is the most common, providing a balanced structure for general use; twill weave offers increased strength and flexibility; and Dutch weave features a dense, fine surface for high-precision filtration.
- Smooth Surface and Aesthetic Appeal: The surface of copper wire mesh is naturally smooth, and over time, it develops a distinctive patina that adds to its aesthetic appeal. This makes it a popular choice for decorative applications, such as architectural facades, interior design elements, and artistic installations, where both functionality and visual appeal are desired.
- Customizable Specifications: To cater to diverse customer requirements, we provide extensive customization options for copper wire mesh. This includes varying mesh counts (from 10 mesh to 600 mesh or higher), wire diameters, mesh shapes (square, rectangular), and sheet sizes. Our technical team works closely with clients to develop tailored solutions that perfectly align with their specific application needs.

FAQ
What is copper wire mesh?
Copper wire mesh is woven from high-purity copper wire (≥99.9% Cu, C1020 oxygen-free). It is valued for its excellent electrical and thermal conductivity, which stainless steel cannot match, plus good corrosion resistance and malleability.
Is copper wire mesh good for EMI/RFI shielding?
Yes. Copper is one of the best electrical conductors, so copper wire mesh effectively blocks and absorbs electromagnetic interference (EMI) and radio frequency interference (RFI). It is widely used in Faraday cages, MRI rooms, grounding and electronic enclosures.
What is copper wire mesh used for?
Copper wire mesh is used for EMI/RFI shielding, grounding, heat exchangers and thermal management, chemical and food filtration, and architectural decoration. Its conductivity also makes it suitable for electrical filters and battery applications.
What is the difference between copper and stainless steel wire mesh?
Copper conducts electricity and heat and blocks EMI/RFI, but develops a green patina over time. Stainless steel is rust-resistant and stronger but does not conduct or shield. Choose copper for electrical, shielding and thermal uses; choose stainless steel for corrosion resistance and strength.
What mesh counts are available for copper wire mesh?
Kawen supplies copper wire mesh from 2 mesh to 300 mesh standard, with ultra-fine meshes up to 600 mesh available on request. It is offered in plain, twill and Dutch weave, in rolls, sheets and cut-to-size pieces.
Does copper wire mesh rust or corrode?
Copper does not rust like steel. When exposed to air and moisture it forms a protective green patina that slows further corrosion. For indoor, dry or mild environments no extra protection is needed; for harsh or marine exposure a coating may be recommended.
