Sintered Highly Porous Metal Foils

Manufacturing Process


  • Based on well established tape casting technology
  • Flexible selection of base metals and alloys
  • Adjustable pore size and porosity
  • Simple shaping in the green state
  • Machinability (punching, blade-cutting, laser/water jet cutting, wire erosion)
  • Suitable for mass production


  • Materials: steel, stainless steel 316L, nickel, copper (other materials on request)
  • Porosity range: 35-85 % I Pore size range: 5-150 µm depending on space holder dimensions
  • Sheet dimensions: max. 180 mm x 240 mm, thickness from 0.2 up to 2.5 mm (other dimensions on request)

Application examples

  • Filters, membrane supports, supports for immobilized micro organisms (i. e. stainless steel 316L)
  • Electrodes in hydrogen technology (i. e. titanium for PEM electrolyzers, nickel for alkaline membrane electrolysis
  • 3D current collectors for lithium ion batteries
