                                  Product Summary of Regular aluminium foam

                                  Goodfellow is delighted to announce the addition of an exciting new product to our range – regular aluminium foam.

                                  So what is this “regular” foam?

                                  Unlike the foams we have had in our catalogue for several years, which are a permeable structure of cells and continuous ligaments in an approximately consistent density, but random orientation, this new foam is made up of cells defined as regular tetrakaidecahedrons (polygons with 14 faces – 8 hexagonal and 6 square).

                                  Prototyping to industrialisation

                                  Prototyping can be accomplished using standard pieces as stocked by Goodfellow, but for production pieces, the final shape can be moulded, reducing costs and eliminating the need for machining.

                                  Impact absorption

                                  For impact absorption, the advantage of this regular, reproducible aluminium foam product is that it can be designed with the end use in mind, making it possible to optimize the exact structure necessary to absorb the energy from an impact based on a specific application.

                                  Heat exchange

                                  It is in heat exchange that this metal foam potentially has the most promise: its high porosity (80-90%) and its very high relative surface area of up to 500 m2/m3 facilitate the movement of fluids and the recovery of heat, even at low speeds.
