Properties of metal foam

WebMetallic foams typically retain some physical properties of their base material. Foam made from non-flammable metal will remain non-flammable and the foam is generally recyclable back to its base material. Coefficient of thermal expansion will also remain similar while thermal conductivity will likely be reduced. WebOct 4, 2024 · As the properties of metal foam mostly depends on its structure, a reliable fabrication process for continuous production is of prior importance. Unavailability of such a process is the major drawback of the material and thus imposes limitations to its full-fledged industrial adoption [ 1, 3 ].
