Linn High Therm GmbH (Germany) has introduced a new powder metallurgical production method that allows practical use of foam metals. In the last few years there has been increasing demand for light design, especially to reduce the energy consumption caused by the acceleration of a mechanical system. However, design changes by themselves cannot lead to weight reduction, because criteria of stability have to be met. Also, the option of using alternative materials such as magnesium alloys, Ti, TiAl etc. is restricted by difficult treatment and high costs. Linn High Therm’s new powder metallurgical production method can be applied to Cu, Ni, Ti, MO and W and other materials, including alloys. By introducing homogenous cell pores with a size between 0.8 and 4.5 mm, the density can be decreased much lower than the value of the basic material: densities as low as 0.25 to 1.0 g/cm³ are feasible. The results show a high reproducibility and better thermal and chemical resistance. Typical applications include mechanical damping elements, electrodes in galvanic engineering, fuel cells, heating elements and cooling designs of reduced weight in laser equipment or power electronics. The large enhanced surface also makes the materials suitable for liquid, gas and melt filters, as supporters of catalysts and for heat exchanger elements.
