Open porous structures offer an outstanding potential to combine material properties with a functionality resulting from their specific morphology. In the last two decades numerous cellular materials were developed based on different technologies and tested in R&D labs around the world. Most well–known is the replication method using polyurethane sponge as a template, which is coated with a powder slurry and enclosed heat treated [1, 2]. The variety of alloys and structural properties is interesting for manifold applications. On the other hand an important base for the customer acceptance of a new material is the availability on an industrial level. A large scale production technology for nickel and iron based metallic foams with open cell structure is described in chapter 3. The powder metallurgical process was developed at Fraunhofer IFAM Dresden in cooperation with ALANTUM. The industrial production line is now established. The alloy metal foam is available as a semi-finished part and the base for the product development together with users for a wide range of applications.
