ADDITIVA_Scalmalloy_rev005.docx
Scalmalloy is an aluminium - magnesium - scandium alloy that offers excellent stiffness, an exceptionally high strength -
to - weight ratio, superb weldability and ductility, and low density to reduce parasitic mass from non - structural
features. It can effectively replace high - strength 7000 series aluminium alloys in plate or forging form. Thanks to its
low density, Scalmalloy provides density - specific properties that are highly competitive, even when compared with
the strongest alternatives. Compared with other al uminium alloys used in additive manufacturing, Scalmalloy delivers
a unique level of corrosion resistance and maintains a highly stable microstructure up to 250°C, making it suitable for
a broad range of high - performance applications.
Combining high strength with excellent ductility and processability, it is the ideal material for heavily loaded
components, which is why it is already employed in many critical applications. Scalmalloy has an established track
record across a wide range o f fields, including a erospace, robotics, marine, and motorsport, and is an approved
material under FIA regulations.
