Brass Wire Mesh – 5 Powerful Secure Uses for Copper

Brass wire mesh is a woven metal mesh with a golden-yellow appearance, produced from brass wire.Brass is a copper–zinc alloy that combines good strength with excellent electrical and thermal conductivity.
The zinc content in brass wire improves abrasion resistance and overall durability, making brass wire mesh suitable for filtration, screening, shielding and decorative applications.The most common grades for brass woven wire mesh are 65Cu and 70Cu, with typical compositions of approximately 65% copper / 35% zinc and 70% copper / 30% zinc. The most widely used weaving style for brass wire mesh is plain weave, offering a stable structure and uniform openings.Our brass woven mesh is produced to tight tolerances and inspected meter by meter to ensure consistent quality.

Chemical Composition of Brass Wire Mesh (Typical)

Element	Symbol	Typical Content (wt%)	Remarks
Copper	Cu	65–70%	Main component of brass wire mesh (65Cu / 70Cu grades)
Zinc	Zn	30–35%	Improves strength and abrasion resistance
Lead (max)	Pb	≤ 0.10%	Improves machinability (may be present in trace amounts)
Iron (max)	Fe	≤ 0.05%	Typical impurity
Others (Sn, etc.)	–	≤ 0.10%	Minor elements, usually controlled as impurities

Physical Properties of Brass Wire Mesh (Typical)

Property	Unit	Typical Value	Remarks
Density	g/cm³	≈ 8.4 – 8.7	Depends slightly on exact Cu/Zn ratio
Melting Point (solidus–liquidus)	°C	≈ 900 – 940	Typical for yellow brass used in wire mesh
Tensile Strength	MPa	≈ 300 – 600	Lower for annealed mesh, higher for hard-drawn wire
Yield Strength	MPa	≈ 150 – 450	Varies with temper and mesh specification
Elongation	%	≈ 5 – 40	Higher elongation for soft/annealed brass wire mesh
Elastic Modulus (Young’s)	GPa	≈ 100 – 110	Typical for Cu–Zn brass alloys
Electrical Conductivity	% IACS	≈ 25 – 30	Lower than pure copper, sufficient for shielding mesh
Thermal Conductivity	W/m·K	≈ 100 – 120	Good heat conduction for screening and industrial use
Hardness	HV	≈ 80 – 150	Depends on wire temper (soft to hard)
Color	–	Golden yellow	Typical appearance of brass wire mesh

Brass Wire Mesh Material & Specifications

Material: Brass wire (also known as yellow copper)

Brass wire mesh has:

Good electrical and thermal conductivity
Excellent plasticity – easy to form by hot and cold working
Good corrosion resistance and wear resistance
Stable square mesh openings, woven from different warp and weft wire sizes

Brass wire mesh range: 1 mesh – 200 mesh
Red copper mesh range: 1 mesh – 80 mesh
Phosphor bronze mesh range: 1 mesh – 400 mesh

The Brass Wire Mesh count (number of warp threads per inch) determines the aperture size.In general, the higher the mesh count, the smaller the opening and the finer the filtration performance.
