VDM Metals International GmbH products

Modern day key industry components are often exposed to high and highest temperatures and require the use of innovative high-temperature alloys. These usually heat-resistant or high-temperature materials have found a wide range of applications not only in furnaces and heat treatment plants, but they are also used as a substrate material for heavily stressed metallic catalysts. Other typical applications are radiant tubes, combustion hoods, hood-type furnaces, controlled atmosphere annealing furnaces, continuous annealing furnaces, ventilators and fans, rotary kilns, and also oil and gas burners.

Super alloys like VDM Alloy 718 are nickel or cobalt based alloys that are, on the one hand, used around significantly heightened temperatures, but on the other hand also in extremely corrosive environments. The driving force in the development of these materials were the increasingly higher requirements of the aviation industry, caused by higher temperatures in turbines. Further areas of application for semi-finished products of Ni-based superalloys are chemical plants with extreme requirements for corrosion resistance as well as nuclear power plants.

Soft magnetic materials are characterized by high magnetic conductivity (permeability) and have a long application tradition in electrical engineering. VDM Metals has been producing soft magnetic iron-nickel alloys for many years in the form of toroidal tape cores, transducers, transformers, heat shields and as yokes and armatures of relays. aThe nickel-iron alloys group with a high nickel content, which contains the VDM® MAG 75 and VDM® MAG 7904, is characterized by a high permeability and low coercive force. VDM® MAG 50 and VDM® MAG 53, with a nickel content of 50 percent both lie in a region of maximum saturation polarization but low permeabilities.
