Brass Diamond Expanded Metal Mesh

Product Introduction

The Brass Diamond Expanded Metal Mesh is a metal fabric formed by slitting and stretching brass sheets (Cu-Zn alloy), featuring diamond-shaped openings, corrosion resistance, and aesthetic appeal. It is widely used in filtration, architecture, electronics, and aerospace industries.

Manufacturing & Structure

1.Process: Brass sheets are slit into diamond patterns and stretched to form uniform meshes, with no material waste (utilization rate >95%).

2.Key Parameters:

●Sheet Thickness: 0.1–1.5 mm (thin for filtration, thick for structural support);

●Pitch (Hexagon Side Distance): 5–20 mm (determines air permeability and protection);

●Strand Width: 0.5–2.0 mm (affects load-bearing capacity).

Material Properties & Surface Treatment

1.Brass (Cu-Zn Alloy):

●Corrosion Resistance: Suitable for marine and chemical environments (superior to mild steel);

●Thermal Conductivity: 100–120 W/(m·K), ideal for heat-dissipation components (e.g., electronic shields);

●Biostatic Effect: Copper ions inhibit microbial growth, meeting medical device standards (e.g., operating room filters);

●Aesthetics: High metallic luster with a vintage patina over time, 适配高端装饰场景 (suits high-end decorative scenarios).

2.Surface Treatments:

●Polishing: Creates a mirror finish for art installations;

●Gold/Nickel Plating: Enhances corrosion resistance or adds functionality (e.g., conductivity, shielding);

●Passivation: Prevents oxidation for long-term color retention.

Applications

1.Filtration & Separation:

●Chemical raw material screening (e.g., catalyst filtration), oil-water separation (ship bilge water filtration);Electronic device dust nets (e.g., server chassis filters, combining heat dissipation and EMI shielding).

2.Architectural Decoration:Facades/screens (using diamond hole light-shadow effects to create industrial or luxury spaces);Ceilings/partitions (60%–80% light transmittance, balancing ventilation and privacy).

3.Industrial Protection:Machinery guards (e.g., precision instrument dust nets, preventing small objects from entering);Aerospace components (e.g., engine oil path filtration, withstanding high temperature and pressure).

4.Acoustic Engineering:Soundproof screens (diamond hole structure absorbs mid-high frequency noise, used in offices or recording studios).

Performance Advantages

1.Mechanical Strength: Stretching redistributes internal stress, improving bending strength by 20%–40% compared to raw sheets;

2.Versatility: Integrates filtration, protection, decoration, and heat dissipation in one solution;

3.Sustainability: 100% recyclable, aligning with circular economy goals.
