AluminiumlegierungfürKolben.
Die Erfindung betrifft eine Verbesserung der in dem Patent Nr. 136576 beschriebenen Legierung.
Es wurden in diesem Patent als neu beansprucht Legierungen des Aluminiums mit einem Gehalt von 15 bis 25% Silizium sowie 0'2 bis 2% Chrom und 0'6 bis 3% von jedem der Metalle Mangan, Kobalt und Nickel. Wie in diesem Patent weiterhin ausgeführt wurde, können diesen Legierungen gegebenenfalls noch 0'6 bis 3% Antimon zugesetzt werden.
Es wurde nun gefunden, dass eine wesentliche Verbesserung dieser Legierung dadurch erreicht
EMI1.1
sammen mit Kupfer in Mengen von 0'6 bis 50 o zugesetzt wird. Der Zusatz des Magnesiums erhöht die Festigkeit und die Gleiteigenschaften, so dass die Eignung zur Herstellung von Kolben, insbesondere von Verbrennungsmaschinen, verbessert wird. Als Beispiel für die Zusammensetzung der nach diesem Patent hergestellten Legierung seien folgende Zusammensetzungen genannt :
EMI1.2
<tb>
<tb> Si <SEP> 22% <SEP> Chrom <SEP> 0#2% <SEP> Mangan <SEP> 1% <SEP> Nickel <SEP> 1#5%
<tb> Kobalt <SEP> 2% <SEP> Kupfer <SEP> 2#5% <SEP> Magnesium <SEP> 1#3%.
<tb>
Die Legierungen, die unter Zusatz von Magnesium bzw. Magnesium und Kupfer hergestellt sind, zeichnen sich durch verbesserte Zug-und Druckfestigkeit aus und weisen höhere Gleiteigenschaften und bessere Bearbeitbarkeit mit schneidenden Werkzeugen auf, ohne dass die Wärmeleitfähigkeit vermindert wird. Schliesslich zeigen sie auch einen verminderten Wärmeausdehnungskoeffizienten, was gerade für die Herstellung von Kolben besonders wichtig ist.
PATENT-ANSPRÜCHE :
1. Aluminiumlegierung für Kolben von Verbrennungskraftmaschinen, Dampfmaschinen usw. mit einem Siliziumgehalt von 15 bis 25% und Metallen der Eisengruppe (Mangan, Chrom, Kobalt, Niekel) gemäss Patent Nr. 136576, dadurch gekennzeichnet, dass die Legierung einen weiteren Zusatz an Magnesium in Mengen von 0'05 bis 5% enthält.

Aluminum alloy for pistons.
The invention relates to an improvement on the alloy described in Patent No. 136576.
Alloys of aluminum with a content of 15 to 25% silicon and 0'2 to 2% chromium and 0'6 to 3% of each of the metals manganese, cobalt and nickel were claimed as new. As further stated in this patent, 0'6 to 3% antimony can optionally be added to these alloys.
It has now been found that this alloy achieves a substantial improvement
EMI1.1
is added together with copper in amounts of 0.6 to 50 o. The addition of magnesium increases the strength and the sliding properties, so that the suitability for the production of pistons, in particular of internal combustion engines, is improved. The following compositions are mentioned as an example of the composition of the alloy produced according to this patent:
EMI1.2
<tb>
<tb> Si <SEP> 22% <SEP> Chromium <SEP> 0 # 2% <SEP> Manganese <SEP> 1% <SEP> Nickel <SEP> 1 # 5%
<tb> Cobalt <SEP> 2% <SEP> Copper <SEP> 2 # 5% <SEP> Magnesium <SEP> 1 # 3%.
<tb>
The alloys which are produced with the addition of magnesium or magnesium and copper are characterized by improved tensile and compressive strength and have higher sliding properties and better machinability with cutting tools without the thermal conductivity being reduced. Finally, they also show a reduced coefficient of thermal expansion, which is particularly important for the manufacture of pistons.
PATENT CLAIMS:
1. Aluminum alloy for pistons of internal combustion engines, steam engines, etc. with a silicon content of 15 to 25% and metals of the iron group (manganese, chromium, cobalt, Niekel) according to patent no. 136576, characterized in that the alloy has a further addition of magnesium in Contains amounts of 0'05 to 5%.
