Features of Expanded Metal Mesh
Small hole titanium expanded metal mesh inherits the excellent properties of titanium materials while exerting unique advantages brought by its small-hole structure, making it widely applicable in high-precision and harsh-environment scenarios. Its core features are as follows:
1. Enhanced Corrosion Resistance with Precision Protection
Based on titanium's inherent stable oxide protective layer, the small-hole structure minimizes the contact area between the mesh surface and corrosive media while ensuring uniform stress distribution. It maintains long-term durability in harsh environments such as strong alkalis, marine salt spray, and chemical reagents, with corrosion resistance even superior to conventional titanium expanded metal mesh in precision corrosion-resistant applications.
2. Outstanding Strength Retention with Compact Structure
It retains titanium's high strength-to-weight ratio (45% lighter than steel with equivalent strength) and adopts an integrated expansion process without welds or joints. The dense small-hole distribution further enhances the mesh's structural rigidity and load-bearing capacity, avoiding deformation under high pressure, vibration, or heavy load conditions while keeping the overall weight low.
3. Excellent Filtration & Electrochemical Uniformity
The uniform small holes (customizable from several micrometers to millimeters) enable high-precision filtration, effectively intercepting micro-particles while ensuring smooth fluid permeability. In electrochemical applications such as electrolysis, fuel cells, and desalination, the small-hole structure increases the specific surface area, ensuring uniform current distribution and stable electrochemical reactions, making it an ideal substrate for MMO-coated anodes.
4. Superior High-Temperature Stability & Biocompatibility
High-Temperature Resistance: Maintains structural integrity and dimensional stability in high-temperature environments up to 600°C, without oxidation or deformation, suitable for high-temperature filtration and thermal processing scenarios.
Biocompatibility: Non-toxic, non-magnetic, and non-irritating to human tissues. The smooth small-hole surface avoids damage to cells, making it widely used in medical fields such as precision implants, biological filtration, and medical device components.
Applications of of Expanded Metal Mesh
1. PEM Electrolytic Water Treatment
This mesh acts as a critical anode for high-efficiency water electrolysis, used to produce ozone or hydrogen for water purification.
Disinfection: Generates powerful oxidizing agents to eliminate bacteria and viruses in industrial and municipal water.
Hydrogen-Rich Water: Used in the production of antioxidant hydrogen water for health and industrial applications.
2. Hydrogen Production (PEM Electrolyzers)
Specifically designed for the oxygen evolution reaction (OER) side of the PEM stack.
Current Collectors: Serves as the primary interface between the bipolar plate and the catalyst layer.
Gas Diffusion Layer (GDL) Support: Provides mechanical support to the membrane while allowing oxygen bubbles to escape through the 2x4mm openings.
3. Electrochlorination & Desalination
Brine Electrolysis: Used in systems that convert salt water into sodium hypochlorite for ship ballast water treatment or power plant cooling systems.
Anti-fouling: Prevents the growth of marine organisms on underwater structures through electrochemical protection.
