Soldering of temperature-sensitive, aluminium based Composites

The joining of temperature-sensitive aluminium matrix composites requires appropriate fillers and adapted joining technologies. Thereby different solutions are possible. On the one hand, the developed, particulate-reinforced tin based fillers are featured by a low process temperature and increased mechanical properties. On the other hand, the developed, ultrasound supported soldering technologies (inductive respectively resistance based heating) allow the use of zinc based fillers. The required heat input is realised locally. In combination with an ultrasound process a fluxless wetting is obtained.
