SinterPore® porous metal filter products can be constructed from one to multiple layers of stainless wire mesh and they are designed for precise, controlled porosity, uniform pore sizes, and distribution. SinterPore® laminates are permanently bonded under precise diffusion bonding (sintering) conditions, yielding robust, monolithic materials used in a wide variety of engineering applications ranging from industrial filtration to aerospace transpiration cooling.

Standard Products And Most Common Uses

  • Standard 2- and 3-layer SinterPore® fluidizing laminates with customer-specific permeability and flow rates are often used in bulk powder handling.
  • Standard 5-layer SinterPore® laminates are used in pharmaceutical, polymer, liquid, and gas filtration.

Specifications: 
  • Standard Sheet Sizes: 18”x48”, 24”x48”. Custom sizes available upon request. Maximum laminate size without welding is 24”x60” (larger sheets available with welds, maximum panel width with welds 120”).
  • Standard Alloys: 304, 304L, 316, 316L, Alloy20 (also available in Inconel 600 and 625, Monel, and Hastalloy upon request).
