This report is a sub project report of a larger project at Swerea SWECAST between 2010 and 2013. The project name is HighT - "Development of High Technology Castings" Within the sub-project the aim was to cast mix materials. In one part of the project, the combination was manganese steel and tool steel. In that part there has been casting trials at Scandinavian Foundry School in Jönköping. In another part of the projet, the combination of different metallic material was white iron and low alloyed steel. In the case with white iron and low alloyed steel a special designed tooth for excavators were designed and cast together with low alloyed steel. The project team is pleased with the results but there are still some questionmarks to straighten out. Hopefully they can be sorted out in a continuation of the project.
