The material selection for wedge filters needs to be determined based on the specific application scenario and performance requirements. Common materials include stainless steel, duplex stainless steel, and alloy wedge wire. The following are specific classifications:
Stainless Steel Materials
304 Stainless Steel:
Advantages: Good processing performance, high strength, smooth surface, suitable for high-precision filtration (such as battery slurry filtration).
Applications: Food, general industrial fluid filtration.
316L Stainless Steel:
Advantages: Strong corrosion resistance (especially resistant to NMP solvent), can be immersed in corrosive media for a long time.
Applications: Battery slurry, chemical, food acid and alkali filtration.
Other Alloy Materials
Duplex Stainless Steel:
Features: Combines the properties of austenitic and ferritic materials, possessing both high strength and corrosion resistance.
Alloy Wedge Wire:
Features: High wear resistance, non-magnetic, suitable for mining screening and the electronics industry.
Support Frame Materials
304 Stainless Steel or Polypropylene Plastic: Used for the frame, balancing strength and corrosion resistance. Galvanized steel sheet, aluminum-magnesium alloy, and polyester fiber composite materials: Select according to the characteristics of the medium. Selection recommendations: Corrosion-resistant applications: 316L stainless steel is preferred. High-precision requirements: 304 stainless steel or custom alloy wire. Special industries (such as electronics and pharmaceuticals): Consider non-magnetic stainless steel.
