Abstract

Ein Druckgusskörper aus einer übereutektischen Aluminium-Silizium-Gusslegierung mit mehr als 15 bis zu 25 Gew.-% Silizium, 0,005 bis 0,3 Gew.-% Zirkonium und mit insgesamt 0 bis 10 Gew.-% an weiteren Nebelegierungsbestandteilen sowie ad 100 Gew.-% Aluminium wird mit einem Druckgussverfahren so hergestellt, dass die Ausscheidung des Primärsiliziums erst in der Gießform erfolgt. Dies wird durch einen Gehalt in der Legierung an Calcium und/oder Strontium von je Element oder in Summe ab 0,001 bis kleiner 0,05 Gew.-% erreicht, wobei der Gehalt an Phosphor kleiner als 0,002 Gew.-% und der Gehalt an Kohlenstoff kleiner als 0,0007 Gew.-% eingestellt wird. Die Erfindung vermindert den Formenverschleiß.

A die-cast body of a hypereutectic aluminum-silicon casting alloy with more than 15 to 25 wt .-% silicon, 0.005 to 0.3 wt .-% zirconium and a total of 0 to 10 wt .-% of other fog alloying ingredients and ad 100 wt % Aluminum is produced by a die casting process so that the precipitation of the primary silicon takes place only in the casting mold. This is achieved by a content in the alloy of calcium and / or strontium of each element or in total from 0.001 to less than 0.05 wt .-%, wherein the content of phosphorus less than 0.002 wt .-% and the content of carbon less than 0.0007 wt .-% is set. The invention reduces mold wear.
