Copper Wire Mesh

Product Introduction

Copper Wire Mesh is a versatile woven mesh product made from high-purity copper wires. Known for its excellent electrical conductivity, thermal conductivity, and natural antimicrobial properties, copper wire mesh is widely used in industries ranging from electronics to pest control. It is available in various weave patterns and aperture sizes to meet diverse application requirements.

Material

Copper wire mesh is manufactured using different grades of copper to suit specific performance needs:

Pure Copper (C11000 / C12200): High conductivity, excellent corrosion resistance, soft and malleable.
Brass (Copper-Zinc Alloy): Enhanced strength, gold-like appearance, good corrosion resistance.
Phosphor Bronze (Copper-Tin Alloy): Superior fatigue resistance, high strength, excellent spring properties.
Beryllium Copper: High strength and hardness, excellent electrical conductivity.

Grade	Composition	Key Features
Pure Copper	≥99.9% Cu	Highest conductivity, soft, antimicrobial
Brass	Cu 60-70% / Zn 30-40%	Decorative, good strength
Phosphor Bronze	Cu 90-95% / Sn 5-10%	Fatigue resistant, springy

Specifications

Copper wire mesh specifications are defined by wire diameter, mesh count, and weave type.

Parameter	Options / Range
Wire Diameter	0.05 mm – 2.0 mm (0.002 in – 0.079 in)
Mesh Count	2 mesh – 200 mesh (openings per linear inch)
Aperture (Opening)	0.08 mm – 8.0 mm (customizable)
Weave Type	Plain weave, Twill weave, Dutch weave
Width	0.5 m – 1.5 m (standard); up to 2.0 m (custom)
Length	10 m – 30 m per roll (or cut-to-size panels)
Open Area	30% – 80% depending on mesh count and wire diameter

Characteristics

Excellent Conductivity: Outstanding electrical and thermal conductivity, ideal for electromagnetic shielding and heat transfer applications.

Antimicrobial Properties: Copper naturally inhibits the growth of bacteria, fungi, and algae, making it suitable for hygienic environments.

Corrosion Resistance: Naturally resistant to atmospheric corrosion and many chemical environments.

Malleability: Soft and easy to cut, shape, and install without fracturing.

Aesthetic Appeal: Distinctive reddish-gold color that develops a natural patina over time.

Non-Sparking: Safe for use in explosive or flammable environments.

RFI/EMI Shielding: Effectively blocks radio frequency and electromagnetic interference.

Lead Time: 5–10 days for standard mesh; 10–20 days for custom specifications.

FAQ

Q1: Does copper wire mesh rust or corrode?

A: Pure copper does not "rust" (iron oxide). It naturally develops a greenish-brown patina over time when exposed to air and moisture. This patina is protective and prevents further corrosion. For applications requiring maintained brightness, brass or coated copper options are available.

Q2: How do I prevent copper mesh from tarnishing?

A: For indoor applications, standard copper will maintain its color longer. To preserve the original reddish finish, we recommend applying a clear lacquer coating after installation, or choosing our pre-coated/anti-tarnish treated copper mesh.

Q3: What is the difference between plain weave and twill weave?

A: Plain weave (over-one-under-one) provides maximum stability and is suitable for most filtration applications. Twill weave (over-two-under-two) allows for a higher mesh count with the same wire diameter, offering finer filtration with greater strength and flexibility.

Q4: Is copper wire mesh safe for use in food processing?

A: Yes, pure copper is naturally antimicrobial and safe for dry food processing applications. For wet or acidic food applications, stainless steel mesh is often recommended. Please consult with our technical team for specific food safety requirements.

Q5: Can copper mesh be used for rodent control?

A: Yes, copper wire mesh is excellent for rodent exclusion. Unlike steel wool, copper does not rust or deteriorate, making it a permanent solution for sealing gaps, vents, and entry points. Its malleability allows it to be stuffed into irregular openings.

Q6: What is the maximum temperature resistance?

A: Pure copper has a melting point of approximately 1085°C (1985°F). For high-temperature applications, phosphor bronze or stainless steel may be more suitable as copper can oxidize at elevated temperatures over time.

Q7: Do you offer custom sizes and cuts?

A: Yes. We can supply copper wire mesh in custom-cut panels, circles, strips, or rolls with specific widths. We also offer fabrication services including edging, framing, and die-cutting.

Q8: Can I get a sample before placing a bulk order?

A: Yes. Free samples of standard meshes are available; you only pay for shipping. Custom samples can be prepared with a lead time of 3-7 days.
