EADS ETL
Technology
Scalmalloy®RP is EADS’ unique second-generation aluminum-magnesium-scandium alloy (AlMgSc) powder. It was developed for rapid prototyping and rapid manufacturing (e-manufacturing) – including the additive layer manufacturing (ALM) process – and displays high strength in layer-wise-generated 3-D near net-shape parts.
Description
EADS’ continued work in AlMgSc alloy technology has resulted in development of the Scalmalloy® alloy family, which offers tailorable material solutions with exceptional fatigue and toughness properties. This alloy powder has proven its applicability on different powder bed build-up platforms. Its part properties are nearly twice of those of established aluminum powder for selective laser melting (direct manufacturing) and can offer exceptional weight saving opportunities if the part design incorporates topology optimization (“bionic designs.”)
Applications
For use in components for transportation, defense, aerospace, leisure and fashion products.
Value-added benefits
Scalmalloy®RP provides robust solutions for the use of aluminum alloys in direct manufacturing approaches when high specific strength, enhanced functionality and exceptional high corrosion resistance – combined with 3-D design freedom – are desired. Compared to all other aluminum alloys currently used in selective laser melting, AlMgSc offers a high level of corrosion resistance, which allows the material’s use without protective coatings.
Scalmalloy®RP, like other AlMgSc alloys, show excellent weldability and good joint strength, enabling complex part integration through any kind of fusion welding.
Status
Available for production applications.
