Nickel mesh

I. Product Introduction Nickel mesh is a metal mesh product made from high-purity nickel wire (N4/N6/Ni99.6, Nickel 200/201) or nickel alloy wire (Monel 400, Inconel 600/625) through processes such as weaving, stamping, stretching, and electroforming.

Core Characteristics:

Extremely strong corrosion resistance: Resistant to strong alkalis, neutral/reducing acids, seawater, hydrofluoric acid; ideal for chlor-alkali/hydrogen production/chemical applications.
Excellent electrical and thermal conductivity: Low resistance, high conductivity; suitable for electrodes, current collectors, and shielding.
High temperature stability: Maintains strength and structural stability even at 600–1200℃.
Diverse structures: Mesh count 1–800 mesh, thickness 0.01–5mm, square/diamond/round/close weave options available.
High precision: Close-weave mesh filtration precision can reach 5–20μm, uniform and stable.

II. Main Production Processes

1. Nickel Wire Braided Mesh (Most mainstream)

Process Flow: Nickel ingot → Wire drawing (Φ0.05–3mm) → Cleaning → Precision weaving → Heat treatment → Leveling → Cutting → Inspection
Weaving methods:
Plain weave: Warp and weft evenly spaced, square mesh, 1–200 mesh, general filtration/electrode application
Twill weave: Interlaced warp and weft, stronger tension, 1–220 mesh Mesh, Pressure Difference

Twill (Dense Weave): Loose warp and dense weft, 45–800 mesh, 5–20μm high-precision filtration

Dutch Weave: Multi-layer dense weave, high density, strong corrosion/gas fine filtration

Features: Soft, uniform mesh, easy to form, moderate cost, widest application

2. Nickel Plate Stretched Mesh (Steel Plate Mesh)

Process: Nickel plate/nickel foil → stamping and slitting → mechanical stretching → diamond mesh → deburring → heat treatment

Features: Highest strength, impact resistance, no waste, thickness 0.1–5mm, wear resistance

Applications: Heavy-duty protection, high-temperature support, strong corrosion screening

3. Nickel Plate Perforated Mesh

Process: Nickel plate/nickel foil → CNC stamping → round hole/square hole/hexagonal/oblong hole → deburring → cleaning

Features: Customizable hole shape, good flatness, high precision, thickness 0.05–5mm

Applications: Electronic shielding, electrodes, filtration, support, decoration

4. Electroformed Nickel Mesh (Special High Precision)

Process: Conductive master mold → Electrodeposition of nickel → Demolding → Heat treatment → Precision cutting

Features: Ultra-thin (0.01–0.1mm), ultra-high precision, uniform micropores, seamless

Applications: High-end filtration, electrodes, electronic shielding, fuel cells

III. Typical Application Areas

1. Chemical Industry and Alkali Production (Largest Application)

Chlor-alkali Industry: Electrolytic cell cathode mesh, brine filtration, alkali conveying filter

Acid-base Filtration: Sulfuric acid/hydrochloric acid/caustic soda/ammonia filtration, distillation column demister

Catalyst Support: Hydrogenation, dehydrogenation, synthesis reaction support

2. New Energy and Hydrogen Production (High-Speed ​​Growth)

Alkaline water electrolysis for hydrogen production: Cathode mesh/Anode mesh/Diffusion layer (core material)

Fuel Cells: Bipolar plates, gas diffusion layer, current collectors

Ni-MH/Lithium Batteries: Current collectors, tabs, busbars, electrode supports

3. Electronic and Electromagnetic Shielding

Electronically mounted bearing mesh, vacuum devices, electrodes, probes, conductive springs
4. Petroleum and Marine Engineering
Oil and gas separation, seawater filtration, desulfurization and denitrification, corrosion-resistant filters for offshore platforms
Pump/valve/pipeline filters, marine equipment fasteners, heat exchanger mesh
5. Pharmaceutical, Food and Precision Filtration
High-precision filtration of pharmaceutical liquids, syrups, juices, sauces
Semiconductor high-purity gas/chemical filtration, laboratory ultra-clean sieving
6. Aerospace and High Temperature
High-temperature engine filters, gas filtration, heat treatment bearing mesh
