Copper foam, now available from Goodfellow, combines the outstanding thermal conductivity of copper with the structural benefits of a metal foam. Its uses include filters and thermal exchange components. These features are of particular interest to scientists working in the fields of medical products and devices, defence systems and flight, power generation, and the manufacture of semiconductor devices.

It is a true skeletal structure - not a sintered, coated, or plated product - and its purity is typically that of the parent alloy metal, with no voids, inclusions or entrapments. The matrix of cells and ligaments is completely repeatable, regular and uniform throughout the material, yielding a rigid, highly porous and permeable structure with a controlled density of metal per unit volume.

Characteristics of copper foam include:

• Optimal heat transfer
  
• High strength-to-weight ratio
  
• High surface area-to-volume ratio
  
• Isotropic load response
  
• Controlled stress-strain characteristics
  
• Can be brazed
  
• Can be coated and plated
  
  

Copper foam is available from Goodfellow in standard pore sizes of 5, 10, 20 and 40 pores per inch (2, 4, 8 and 16 pores per cm), with a density range of 3 to 12%. However, the foam can be compressed to achieve higher densities (up to about 70%) and smaller pore sizes (as high as approximately 500 pores per inch / 200 pores per cm).
