Aluminium (AlSi10Mg)


Metall 3D-Druck mit Aluminium

Aluminium ist eine Legierung mit guten Schmelzeigenschaften, die typischerweise für die Herstellung von Gegenständen mit geringer Dicke oder mit komplexen Geometrien verwendet wird. Sie bietet eine gute Beständigkeit und Härte an, und wird daher für Komponenten benutzt, die starker Belastung ausgesetzt sind.
Erzeugnisse aus AlSi10Mg sind für die Anwendungen besonders geeignet, die gute Wärmeeigenschaften und ein geringes Gewicht erfordern. Das Werkstück kann, falls notwendig, geschweißt, dem Drahterodieren oder der Feinstrahlung unterzogen, poliert oder beschichtet werden. Normalerweise werden die Erzeugnisse aus dieser Legierung einer Wärmebehandlung unterzogen, um ihre mechanischen Eigenschaften zu verbessern.
