Metal foams are cellular structures made of solid metal, often aluminum, with gas-filled pores, exhibiting high porosity with only 5-25% being the base metal. They can be categorized into closed-cell and open-cell types and are notably effective in applications such as heat exchangers and radiation shielding. The document also touches on manufacturing methods and provides a link to further information about aluminum foam and its market.

3. Metal Foams
• 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.
