Metallic Foam or Metal Foam
Metallic foam, also known as metal foam, is a cellular structure consisting of a solid metal, frequently aluminum, with gas-filled pores comprising a large portion of the volume. The unique properties and structure of metallic foams allow them to be used in various applications across different industries.
Metallic foams are a porous ceramic material with a highly interconnected network of holes and cell stems with a cellular structure.
Metallic foams are produced using reticulated polyurethane foam as the base raw materials. The reticulated polyurethane foam is immersed in a liquid bath that coats the reticulated foam structure. After further processing, the metallic foam is produced having the same structure of holes and cell stems as the original reticulated foam but without any polyurethane foam remaining.
The primary application for metallic foams is for filtration of molten metals to remove impurities and improve the metal product's quality
