The performance and lifespan of precision metal filter discs are highly dependent on raw material selection.
Stainless Steel (e.g., 304/316L): The preferred choice for medical sterilization, food processing (e.g., dairy filtration), and chemical applications due to its corrosion resistance (withstands acids/alkalis), high-temperature tolerance (up to 800°C), and excellent filtration precision (down to 0.1 micron). It effectively traps particles to ensure product purity.Copper: Widely used in potable water treatment systems (e.g., water purifier cartridges) because of its natural antibacterial properties (>99% inactivation rate) and superior malleability, which supports customization of complex structures.
Nickel Alloys (e.g., Hastelloy): Renowned for extreme environment adaptability, offering exceptional high-temperature resistance (1200°C) and strong corrosion resistance (withstands hydrofluoric acid). Ideal for petrochemical (e.g., FCC flue gas filtration) and aerospace applications.
Iron-Based Discs: Primarily used for low-cost coarse filtration scenarios (e.g., industrial wastewater pre-treatment).
Material selection requires a holistic assessment of fluid characteristics (pH, particle size), operating temperature, and cost-effectiveness.
