Tinn walled aluminium castings and mechanical properties.

The project was divided into two different research areas:

  • Part A: Rapid Tool making and casting simulation
  • Part B: Material properties

Jönköping University was manly active in the group of material properties.

Material properties

The work in this part of STALPK was focused on following goals

  • 10% ultimate elongation for the best alloys
  • Possibilities to predict mechanical properties by simulation
  • Increased thermal conductivity
  • Reduction of casting weight, for demonstrators, manufactured at gravity die casting and high pressure die casting by reduction of wall thickness.
