High-Conductivity Copper Wire Mesh for Filtration, Shielding, Crafting, and Decorative Industrial Applications

Copper wire mesh is a flexible, durable, and highly conductive woven metal fabric made from over 99% commercially pure copper. Known for its exceptional electrical and thermal conductivity, natural corrosion resistance, and non-magnetic properties, copper mesh is widely used in both industrial and decorative applications.

This woven mesh resembles a fine metallic cloth, with copper wires interlaced at precise right angles. It offers excellent formability—soft enough to be cut with standard scissors, yet strong enough to be welded into rigid, uniform sheets. Its unpolished surface gives it a raw, authentic look that naturally oxidizes over time, developing a distinctive red-orange patina that enhances its visual appeal.

Compliant with ASTM E2016-06 standards, our copper wire mesh is available in a wide range of mesh counts, wire diameters, and opening sizes. It can be customized to suit various functions, from precision filtration and EMI/RFI shielding to pest exclusion and metal art design.

Weave Types Available

Plain Weave

Plain Weave is the simplest and most common weave pattern for woven wire mesh. In this design, each wire passes alternately over and under one wire in both the warp (longitudinal) and weft (transverse) directions, forming a criss-cross pattern with square openings. This straightforward structure provides a good balance between filtration and flow rate, making it suitable for applications where moderate particle retention and consistent flow are required. Its inherent strength and durability also make it a reliable choice for general-purpose filtration tasks.

Twill Weave

Twill Weave is a more intricate pattern where each wire passes over two wires and under two wires, with an offset in each row that creates a distinctive diagonal appearance. This design allows for a tighter mesh with smaller openings compared to Plain Weave, even when using wires of the same diameter. As a result, Twill Weave offers finer filtration while maintaining higher flow rates due to its increased open area. It is ideal for applications requiring enhanced particle retention without significantly compromising fluid throughput.

Plain Dutch Weave

Plain Dutch Weave introduces a variation by using wires of different diameters: thicker warp wires and thinner weft wires. The weft wires are woven in a plain weave pattern—over and under one warp wire—but the differing wire sizes produce slot-like, rather than square, openings. This structure excels at retaining very small particles while still allowing a relatively high flow rate, making it a popular choice for fine filtration needs. The thicker warp wires also contribute to good durability, enhancing its suitability for demanding applications.

Twill Dutch Weave

Twill Dutch Weave combines the Dutch weave concept with a twill pattern. Like Plain Dutch Weave, it uses thicker warp wires and thinner weft wires, but the weft wires pass over and under two warp wires with an offset, similar to Twill Weave. This results in an even tighter mesh than Plain Dutch Weave, enabling finer filtration capabilities. Additionally, Twill Dutch Weave can withstand higher pressures and maintain good flow rates, making it well-suited for applications requiring precise filtration under challenging conditions.

Applications of Copper Wire Mesh

EMI/RFI Shielding & Faraday Cages. Effective barrier against electromagnetic interference—widely used in electronics, telecom, medical (e.g., MRI suites), and aerospace contexts.

Heat Transfer Systems. Used in industrial heat exchangers, HVAC grids, and cooling assemblies for efficient heat management.

Filtration & Sieving. Fine meshes serve in oil, gas, chemical, water treatment, and lab-grade particulate filtration.

Pest & Rodent Control. Knitted/expanded mesh blocks rodents, birds, and slugs—ideal for garden, structural gaps, chimney caps.

Architectural & Decorative Designs. Used for façade cladding, interior partitions, art installations, mantel and ceiling features.

Medical & Hygiene Use. Antimicrobial properties suit it for surgical tools, wound filters, touch surfaces in hospitals, food, and transit areas.

Marine & Aquaculture. Copper mesh resists biofouling, reducing algae and microbial growth in marine fencing and aquaculture environments.

Crafting, Sculptures & DIY. Malleable for artisanal and hobbyist uses—from wire art to custom decorative screens.
