Description
Metal foams are at the forefront of technological development for the automotive, aerospace, and other weight-dependent industries. They
are formed by various methods, but the key facet of their manufacture is the inclusion of air or other gaseous pockets in the metal structure.
The fact that gas pockets are present in their structure provides an obvious weight advantage over traditionally cast or machined
solid metal components. The unique structure of metal foams also opens up more opportunities to improve on more complex methods of producing
parts with space inclusions such as sand-casting. This guide provides information on the advantages metal foams possess, and the applications
for which they may prove suitable.
