High strength nano reinforced aluminium powder cored wire for arc based ALM - AluNanoCore

Project summary

Cost effective wire arc-based additive manufacturing (ALM) processes have the potential to deliver high build-up rates for large volume components. However, for the production of lightweight components, there exist currently only a limited range of low strength standard solid wires. The project objective is to develop a carbon nanostructure reinforced aluminium cored wire (AluNanoCore), which represents a fundamentally new type of filler material for wire arc ALM. The main technological goal of the development is a strength increase of three times compared to conventional AlSi-based materials. Due to this significant increase in strength, lightweight components with reduced wall thicknesses and cross sections can be produced. A new class of Al material will be available for the additive production of lightweight components, which has a superior strength-to-density ratio. The validation and demonstration of the project results will be carried out on at least two demonstrators.
