Combining the benefits of metallic 3D printing with new materials can greatly expand the possibilities for modern components.” This is how Airbus APWorks CEO Joachim Zettler describes the goal in the development of Scalmalloy®. In cooperation with Airbus Group R&D the company developed a high-performance aluminium powder. It is corrosion-resistant and combines the low weight of aluminium with almost the specific strength of titanium. In comparison, the AlSi10Mg aluminium silicon powder widely used for additive manufacture is only half as strong. In addition to its high strength, Scalmalloy® is also very tough; a special advantage for safety-related applications.
This unique combination makes our material especially interesting for high-performance applications in the robotics, automotive and aerospace industries. Together with the design freedom afforded by metallic 3D printing, products can also have levels of functionality that were previously unattainable
Scalmalloy® is produced and marketed exclusively by APWorks, in order to make aerospace quality achievable in other industries as well.

Values stated in the datasheet refer to the minimum properties that are reached using Additive Layer Manufacturing in the least strong direction of the material.
The values of the mechanical properties are generated from tests according to DIN EN 2002-001 standards from specimens that have been heat treated and machined.
* The surface roughness values depend on the measurement method used and the orientation of the surface. The values quoted here give an indication of what can be achieved for certain surfaces.
