Webinar: Aluminum A205: A New High-Strength Alloy for GE Additive's Concept Laser M2 Series 5 Machine

M2 Series 5

A205 is a lightweight aluminum alloy derived from the aerospace approved A20X™ alloy. Due to a unique solidification mechanism, this material exhibits a highly refined microstructure leading to exceptional high strength, exceeding the yield strength of AlSi10Mg by more than 150 MPa (+60%) in the heat-treated state. Additionally, A205 demonstrates excellent thermal stability, stress corrosion resistance and comparatively superior fatigue properties to other AlSi-based additively manufactured alloys. These superior properties – achieved through high cooling rates to create a high-density, crack-free and finely scaled dendritic microstructure – makes the alloy an excellent choice for additively manufactured applications.

Join this webinar to learn about the fundamental steps undertaken to develop the A205 parameters and find out about the capability and robustness of this new parameter set for GE Additive’s Concept Laser M2 Series 5 DMLM machine.

Martin Pröbstle
Advanced Lead Process Engineer
GE Additive

Martin is an advanced lead process engineer in the Process and Application Development team, responsible for the development of aluminum alloy parameters for manufacturing. He is leading the A205 parameter development program on the M2 Series 5. Before joining GE, Martin worked as a research assistant at the University Erlangen-Nuremberg, which is where he developed an interest in additive materials. Martin holds a Ph.D. in Material Science and Engineering, characterizing the microstructure and mechanical properties of conventional as well as additive manufactured nickel-based superalloys.
