Zinklegierung, insbesondere für Spritzguss.
EMI1.1
2-10%, vorzugsweise 4% Aluminium und Rest Zink kennzeichnet, wobei die Zinkkomponente aus einer Zinksorte besteht, die mindestens 99-99% Zink neben höchstens 0-01% Blei und Kadmium enthält.
Es wurde nun gefunden, dass ein höherer Gehalt an Kupfer als jener der vorangegebenen Legierung des Stammpatentes die Zugfestigkeit derselben zu verbessern geeignet ist, wobei die Überlegenheit der Legierung gegenüber den vorbekannten Zinklegierungen im Wesen bewahrt bleibt, bei welchen die Zinkkomponente wohl aus hochwertigem Zink, nicht aber aus Zink von ganz hervorragender Reinheit (99'99% Zink und mehr) besteht.
Die vorliegende Erfindung betrifft daher Zinklegierungen, insbesonders für Spritzguss, die im Wesen frei von Magnesium sind, ungefähr 2-10% Aluminium, dagegen Kupfer nicht mehr im Ausmasse von 0-05-2%, sondern von mehr als 2% und weniger als 6% enthalten und in welchen das Zink ein solches von ausserordentlicher Reinheit ist. Die bevorzugte Zusammensetzung einer Legierung nach der Erfindung ist folgende : Ungefähr 4% Aluminium, ungefähr 3% Kupfer und im übrigen Zink von hoher Reinheit, also mit etwa 99'99% Zink.

Zinc alloy, especially for injection molding.
EMI1.1
2-10%, preferably 4% aluminum and the remainder zinc, the zinc component consists of a type of zinc that contains at least 99-99% zinc in addition to a maximum of 0-01% lead and cadmium.
It has now been found that a higher copper content than that of the previous alloy of the parent patent is suitable for improving the tensile strength of the same, the superiority of the alloy being retained in essence over the previously known zinc alloys, in which the zinc component is probably not made of high quality zinc but consists of zinc of excellent purity (99'99% zinc and more).
The present invention therefore relates to zinc alloys, in particular for injection molding, which are essentially free of magnesium, approximately 2-10% aluminum, whereas copper no longer amounts to 0-05-2%, but more than 2% and less than 6% % and in which the zinc is of extraordinary purity. The preferred composition of an alloy according to the invention is as follows: approximately 4% aluminum, approximately 3% copper and the remainder zinc of high purity, i.e. with approximately 99.99% zinc.
