Flattened Titanium Diamond Mesh Sheets for MMO Anodes & Water Treatment

Description of Expanded Metal Mesh

Flattened Titanium Diamond Expanded Metal Mesh is a high-precision industrial material produced by slitting and stretching high-purity titanium foil (typically Grade 1 or Grade 2), followed by a flattening process. This ensures a smooth, two-dimensional surface without the "knuckles" or raised edges found in standard expanded metal.

Surface Finish: Smooth and burr-free, which is essential for ensuring uniform coating adhesion and preventing damage to delicate membranes.

Material Integrity: Maintains the chemical inertness and superior strength-to-weight ratio of titanium.

Structure: The jointless, continuous diamond pattern provides excellent electrical conductivity and mechanical stability.

Corrosion Resistance: Highly resistant to strong acids, alkalis, and chloride ions—environments where stainless steel typically fails.

Specification of Expanded Metal Mesh

Features of Expanded Metal Mesh

Flattened Titanium Diamond Expanded Metal Mesh  are low energy mesh materials to replace conventional cast or cold rolled lead anodes. Fit for new and already established EW operations, the titanium metal substrate with a fully amorphous coating offers a considerable cut down in cell voltage as compared to the standard lead anodes or crystalline coated titanium anodes. Even  it also avoids the precipitation of unwanted contaminants like manganese and lead oxides.
The lead anodes pose a challenge for EW operations in handling and disposing of lead waste. The cells need to be cleaned by operators to eradicate lead sludge accumulation that can be risky to health and safety of an operator. Unlikely, the titanium anodes avoid this need.
Additionally, the titanium anodes do not need to be stabilized by adding cobalt sulfate to the electrolyte. Preventing cobalt from EW process decreases the operation cost and with titanium anodes there is no need to electrically separate the cells that increases the plant availability and productivity.

Applications of of Expanded Metal Mesh

1. MMO Anodes (Mixed Metal Oxide)

Flattened titanium mesh is the industry-standard substrate for MMO Anodes. The mesh is coated with precious metal oxides (like IrO₂, RuO₂, or Ta₂O₅) to create a high-performance electrode.

Cathodic Protection: Used in pipelines, marine structures, and reinforced concrete to prevent rust.

Electrochlorination: Efficiently generates chlorine from saltwater for pool disinfection or industrial cooling towers.

Electrolysis: Serves as a stable electrode for hydrogen and oxygen evolution in fuel cells and electrolyzers.

2. Water Treatment & Desalination

The material’s durability makes it a primary choice for harsh aquatic environments.

Seawater Desalination: Used in pretreatment filtration and condensers to resist the corrosive effects of concentrated brine.

Wastewater Treatment: Acts as a stable anode for the electrochemical degradation of organic pollutants and heavy metal recovery.

Bio-fouling Resistance: Titanium’s biocompatibility reduces the buildup of microorganisms and algae, keeping filters clean longer.

3. Energy & Chemical Processing

Fuel Cell Electrodes: The flattened profile is critical for stack assembly, providing a consistent contact surface for proton exchange membranes (PEM).

Precision Filtration: Ideal for filtering aggressive chemicals where high purity and zero-contamination are required.
