Metal Filter Mesh Discs

 Material Characteristics

1. Stainless Steel: The most commonly used material for metal filter mesh discs, stainless steel (especially 304 and 316 grades) offers excellent corrosion resistance, high temperature tolerance (up to 800°C for 316), and cost-effectiveness. 316L, with its low carbon content, provides superior resistance to intergranular corrosion, making it ideal for chemical processing and marine applications.
2. Copper and Brass: These materials excel in applications requiring good electrical conductivity and thermal transfer, along with moderate corrosion resistance. Brass discs, in particular, offer enhanced durability and a golden aesthetic, suitable for both functional filtration and decorative purposes in specific industries.
3. Nickel and Nickel Alloys: Nickel-based discs provide exceptional resistance to alkaline solutions, organic chemicals, and high temperatures, making them suitable for aerospace, petrochemical, and high-purity applications. Alloys like Hastelloy and Monel extend this performance to extreme corrosive environments, including exposure to strong acids and seawater.
4. Specialty Alloys: For unique challenges—such as extreme heat (FeCrAl for temperatures up to 1200°C) or nuclear radiation (titanium)—specialty alloy discs deliver tailored performance, ensuring reliability in critical operations.

Structural Characteristics

1. Precision Mesh Construction: Metal filter mesh discs are fabricated using advanced weaving or sintering techniques to achieve uniform mesh openings, ensuring consistent filtration accuracy. Weaving methods include plain weave, twill weave, and Dutch weave, with Dutch weave offering finer filtration (down to 1 micron) due to its tightly packed wires.
2. Reinforced Edges: To enhance structural stability and ease of installation, many discs feature reinforced edges—such as crimped, welded, or flanged borders. These edges prevent fraying, improve handling, and ensure a secure fit in filter housings or machinery.
3. Multi-Layer Design: For complex filtration needs, multi-layered discs combine different mesh densities or materials to achieve graded filtration (removing particles of varying sizes in a single pass) or enhanced strength. This design is particularly useful in high-pressure applications where durability is critical.
4. Customizable Thickness and Rigidity: Discs can be manufactured with varying thicknesses (from 0.1mm to 5mm) to balance flexibility and rigidity. Thicker discs are ideal for high-pressure environments, while thinner options offer lightweight performance in low-stress applications.
