Mesh is normally knit from wires ranging in diameter from .0035” to .0200”. In special applications, Metal Textiles has knit wires ranging in diameter from .0005” to .0350”. These wires can be round or flat such as those used in Metal Textiles copper gauze for cleaning and in air-filtration applications where large surface areas of wire are needed. A round wire when flattened has approximately twice as much surface area.
In filtration applications, wire diameter is perhaps the most important design variable. It directly affects flow, dirt holding capacity, pressure drop and cost. In general, larger diameter wire allows for higher flow but provides lower dirt holding capacity. Also, larger diameter wire is less expensive. Therefore, a balance must be struck between using a higher density filter of higher cost fine wire or a lesser density filter using lower cost heavy wire.

Density refers to the mass of material per unit volume. It is related to the density of the original mesh and the amount of forming pressure used to compress the mesh into its final form. Determining the required mesh density to produce the specified final product density is a critical step in the design process. Proper density ensures optimal performance of the sealing, gasketing, filtration, heat transfer and separation applications.
Metal Textiles engineers are expert at determining proper density for specific requirements.
