+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.
