Brass Wire Mesh Cloth: 10 Best Features (Ultimate Guide)

Brass wire mesh cloth (yellow copper screen) is a woven wire fabric made from copper-zinc alloys. It combines clean, stable filtration with electrical conductivity, non-sparking safety, and a premium gold appearance. Common raw-material families include:

Brass (Cu–Zn alloy) — e.g., 65 brass (~65% Cu / 35% Zn) and 80 brass (~80% Cu / 20% Zn).
Pure copper meshes (for maximum conductivity and EMI/RFI shielding).
Bronze meshes (Cu–Sn) where extra wear and corrosion performance are needed.

Brass mesh is supplied in plain and twill weaves for screening/structural uses, and in Dutch/plain-Dutch/twill-Dutch for tighter microns. Decorative variants (often called “human” weave and bamboo weave) are also available.

It is made of copper wires divided by warp and weft. The mesh is generally square. Used for sieving various particles,powder,porcelain clay and glass, porcelain printing, filtering liquid, gas, etc.

Material:brass wire
Features:non-magnetic, wear-resistant, and good ductility
Specification:3 mesh / inch—200 mesh / inch
Weaving:plain weave, twill weave
Uses:Screen all kinds of particles, powder, porcelain clay, glass, porcelain printing, filter liquids and gases

Phosphorus copper mesh

Phosphorus copper mesh is also known as a raw material with excellent value characteristics. It is attributed to tin bronze mesh.It has the advantages of corrosion resistance, acid and alkali resistance, and strong wear resistance and ductility. It can generally be used in special filtration, impurity removal, and production. Together in some shielding, home wall blocking.

Red copper mesh

Red copper mesh is a kind of red copper wire, which is used for radiation protection of special facilities such as cable circuits,laboratories, and computer rooms. Anti-electromagnetic interference in electronic equipment, power sector,aerospace,information industry, military facilities, etc.

Material:copper wire

FAQs: Brass Wire Mesh Cloth

What is brass wire mesh cloth?

Brass wire mesh (also called brass cloth or brass screen) is a woven wire fabric made from copper–zinc alloys, typically C260 (~70% Cu / 30% Zn) or C270 (~65% Cu / 35% Zn). It offers clean filtration, conductivity, and a gold appearance.

How does brass mesh differ from copper or bronze mesh?

Brass is harder and more wear-resistant than pure copper while remaining conductive. Bronze (Cu–Sn) is chosen when extra corrosion and abrasion resistance are required.

What weave styles are available?

Standard weaves are plain and twill. For fine filtration, Dutch weaves are used: plain-Dutch, twill-Dutch, and reverse-Dutch. Decorative options (e.g., “human” and “bamboo” weaves) are also available.

What mesh counts and wire diameters are typical?

General stock spans about 3–200 mesh with wire diameters roughly 0.04–1.0 mm for screening grades. Finer Dutch weaves use smaller wires and higher counts for micronic filtration.

What are common roll sizes?

Typical widths: 1.0 m, 1.2 m, 1.5 m, 1.8 m, 2.0 m (others on request). Common lengths: 30 m, 50 m, 100 m. Cut-to-size discs, rings, and panels are standard.

Is brass wire mesh conductive and non-sparking?

Yes. Brass conducts electricity and is non-sparking, making it suitable for EMI/RFI shielding and use near sensitive or combustible environments.

What applications use brass mesh?

Filtration and sieving (powders, liquids, gases), EMI/RFI shielding screens, insect and vent screens, printing/ceramics, instrument filters, and architectural panels (cabinet doors, radiator covers, façades).

How effective is brass mesh for EMI/RFI shielding?

Brass Wire Mesh Cloth Effectiveness depends on mesh count, wire diameter, thickness, and enclosure design. Finer meshes with smaller apertures generally provide higher attenuation.

How does brass resist corrosion?

Brass performs well in many neutral environments and develops a protective patina. It is not ideal for strong ammoniacal solutions or long-term, aggressive chloride exposure without protection.

Can Brass Wire Mesh Cloth be used outdoors?

Yes. Expect natural patination (darkening). For a bright finish, specify clear lacquer or protective coatings; for coastal sites, evaluate alloy choice and coating durability.

What standards should I reference?

For woven wire cloth: ASTM E2016. For woven wire filter cloth (Dutch weaves): ASTM E2814. For terminology, tolerances, and test methods across metals: ISO 9044.

What tolerances matter most when ordering?

Specify mesh × wire, nominal aperture/micron, thickness (if critical), width/length, flatness, and acceptable variance per the governing standard. Include lot/material certificates when required.

How is brass mesh fabricated?

It can be cut, sheared, punched, folded, framed, soldered, and brazed. For discs, rim-welding or edging helps maintain shape and prevent fray.

What’s the difference between plain, twill, and Dutch weaves?

Plain: one-over, one-under; good strength and flow.
Twill: two-over, two-under; higher density and dP capability.
Dutch (plain/twill/reverse): dissimilar warp/weft counts/diameters to form tiny pore channels for micronic retention.

What micron levels can Dutch brass weaves achieve?

Depending on exact construction, Dutch weaves can reach tens of microns and below for liquid/gas polishing. Always quote the required nominal or absolute micron target.

How do I choose between brass, phosphor bronze, and stainless steel?

Choose brass for conductivity, non-sparking behavior, easy forming, and aesthetics; phosphor bronze for added wear/corrosion resistance; stainless for aggressive corrosion, high strength, or elevated temperatures.

How should brass mesh be packed for shipment?

Rolls: rigid cores, edge guards, anti-tarnish/VCI inner wrap, moisture-barrier outer wrap, carton or wooden case.
Cut parts: nested with interleaves, polybagged, foam-lined cartons or crates, labeled by alloy, mesh × wire, aperture/micron, and lot number.

What maintenance is recommended?

Clean with air blow-off, mild solvent, or ultrasonic methods. Avoid prolonged exposure to strong ammonia. For appearance, use non-abrasive cleaners and consider protective coatings.

What information should I provide for a quote?

Alloy/grade, weave type, mesh × wire (both directions for Dutch), target aperture/micron, size/quantity, temper, finish/coating, standards (ASTM/ISO), and packing preferences.

Can you supply custom shapes and multi-layer packs?

Yes. Common customs include discs, rings, cones, cylinders, and multi-layer laminates (including sintered packs) built to drawing, with optional frames and welding.
