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.
