Anticorodal

Anticorodal® – infinitely adaptable
As Anticorodal alloys can be adapted to virtually all different fields of work and casting methods, countless possible uses are emerging for this material. Outstanding mechanical properties, electrical conductivity, corrosion resisting thanks to low silicon content, but slightly harder to cast. As with Silafont alloys, to enjoy cost-effective use, it is well worth providing a complete definition of the material being used and tailoring it to both the parts to be produced and your casting process.

The creatures of the sea provide the natural metaphor for this alloy. Such creatures adapt to different conditions and have developed a whole series of special attributes in order to do this.


Anticorodal®-04 [ AlSi0,5Mg ]

Areas of use
