Metal Foams

Open-cell metallic foams are ideal for combining material properties with functionality resulting from their specific morphology. Fraunhofer IFAM Dresden has many years of experience in adapting commercially available element foams to the highest requirements. Special coating technologies and heat treatments have been developed to create passivation or functional layers that ensure excellent durability and high reactivity.

In addition, through close cooperation with Alantum corp. we have a reliable partner for the supply of high quality foams, upscaling and industrial production of open cell metallic foams.

If you have any questions or specific problems, please do not hesitate to contact us. We will find the best solution for you.
