Metallic Foams, New Generation of the Environmental Friendly Materials

Metallic foams or Metfoams are a new class of advanced materials in environmental friendly materials group. These materials are the family of the cellular materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They are recyclable and nontoxic. They hold particular promise for market penetration in applications in which several of these features are exploited simultaneously. Recent technological advances in the field of metallic foams have led to the development of a wide range of processing techniques for the open, as well as closed cell morphologies. The processing route has to be decided on the basis of the cost of production, material properties, and the intended applications of the final product.
