MetaFoam Copper-Silver Foam
Categories: Metal; Metal Foam, Mesh, or Honeycomb; Nonferrous Metal; Copper Alloy

Material Notes: General Description:

MetaFoam® Technologies intends to revolutionize the open-cell metal foams industry by alleviating the major constraints of “conventional” metal foams. MetaFoam can significantly increase specific surface area and repeatability, while maintaining the lowest production costs. MetaFoam is uniquely positioned to develop products and address several needs in various industries and markets.

Applications:

There are plenty of fields of applications for open-cell metal foams, including:

  • Thermal management and heat transfer
  • Electrochemistry and catalysts
  • Water and air purification/filtration
  • Biomedical implants
  • Flow control devices
  • Acoustic
For now, MetaFoam is focusing on particular applications:
  • Metal foam wicking structure for cylindrical, flat, and loop heat pipes that perform in any orientation
  • Cold plates with a metal foam core for electronics cooling without the high cost of micromatching
  • High surface area boiling / evaporator plates for increased critical heat fluxes
  • High surface area porous electrodes to increase electrochemical reaction efficiency
  • Water purification with copper-silver foams, two metals having renowned properties against bacteria and algae.
