  • Coating a polyurethane foam with a metal powder-binder suspension
  • Production of the metal foam by debinding (chemical/thermal) and sintering
  • Flexible material selection - almost all metals or alloys available as powder can be processed
  • Adjustable cell width and porosity
  • Process suitable for series production

Specifications

  • Materials:
    - Alloyed and unalloyed steels (e.g. C45, 304L, 316L, 42CrMo4)
    - Pure metals (e.g. iron, titanium, copper, molybdenum, tantalum, precious metals)
    - Fe-Cu, Ni-based alloys, Ti6Al4V
    and many more
  • Porosity: 70-96 %
  • Cell width: 0.4-5.0 mm (80 ppi - 10 ppi)
  • Specific surface: 400-5300 m2/m3

Applications

  • Electrodes or catalyst carriers
  • Heating elements, vaporizers, surface burners
  • Synthetic replacement for natural bone tissue
