Metal foamWikipedia
A metal foam is a cellular structure consisting of a solid metal (frequently aluminium) with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam).The defining characteristic of metal foams is a high porosity typically only 5–25 of the volume is the base metal.The strength of the material is due to the
