Description

Die Erfindung betrifft eine warmfeste Aluminium-Sinterlegierung, insbesondere für Kolben von Brennkraftmaschinen, nach Patent 23 39 844.The invention relates to a heat-resistant aluminum sintered alloy, in particular for pistons of internal combustion engines, according to patent 23 39 844.

Bei der Legierung nach jenem Patent ist für die Metalle Kupfer, Eisen, Nickel und Chrom ein Gesamtanteil von 2 bis weniger als 5% angegeben.In the alloy according to that patent, the metals copper, iron, nickel and chromium have a total proportion stated from 2 to less than 5%.

Es hat sich nun überraschenderweise gezeigt, daß sich die Wann- und Verschleißfestigkeit noch dadurch steigern läßt, daß gemäß Anspruch 1 lediglich für die Metalle Eisen, Nickel und Chrom in ihrer Gesamtheit der Bereich von 2 bis weniger als 5% eingehalten wird, während der Kupfergehalt in allen Fällen 0,3 bis 5% beträgtIt has now been shown, surprisingly, that the when and wear resistance are still thereby Can increase that according to claim 1 only for the metals iron, nickel and chromium in their entirety the range from 2 to less than 5% is adhered to, while the copper content in all cases 0.3 to 5% amounts to

Besonders gute Werte in bezug auf hohe Warmfestigkeit, bei gleichzeitig guten Eigenschaften hinsichtlich Verschleißfestigkeit, Dehnungs- und Wärmeleitfähigkeit weisen die bevorzugten Legierungszusammensetzungen nach den Unteransprüchen auf.Particularly good values with regard to high heat resistance, with good properties in terms of wear resistance, elongation and thermal conductivity at the same time have the preferred alloy compositions according to the subclaims.
