Aluminium

Aluminium (AlSi10Mg)


Die Produktionen in A1Si10Mg bieten eine gute Beständigkeit und Härte und daher wird es normalerweise bei der Herstellung von Komponenten verwendet, die hohe Belastungen aushalten müssen und bei Anwendungen, die gute thermische Eigenschaften und Leichtigkeit erfordern.


Es handelt sich um eine Legierung mit guten Schmelzeigenschaften, die normalerweise bei der Produktion von Elementen mit dünnen Strukturen und komplexer Geometrie verwendet werden.
