Verfahren zur Herstellung von Aluminiumlegierungen.
Ataminiumiegierungen, welche neben Aluminium noch Kupfer, Zinn, Antimon und Magnesium enthalten, sind an und für sich bekannt ; eine typische Legierung dieser Art ist durch die österreichische Patentschrift Nr. 5842 bekannt geworden. Diese Legierung, die leicht bearbeitbar und gegen Einfluss von Säuren und Oxydationsmitteln ungemein widerstandsfähig ist, hat den Nachteil, dass sie zu weich, daher insbesondere nicht zu Kochgeschirren verwendbar ist. Wohl könnte durch grösseren Zusatz von Kupfer und Antimon die Härte der Legierung erhöht werden, wie aber die genannte Patentschrift selbst ausführt, ist dies nur unter Erhöhung der Sprödigkeit möglich, was natürlich unerwünscht ist.
Gemäss vorliegender Erfindung wird ein Teil des Kupfergehaltes durch Mangankupfer ersetzt, und zwar so, dass die Kupfermenge etwa doppelt so gross ist, als die Menge an Mangankupfer.
Als Reinigungsmittel wird hiebei vorteilhaft Potasche (RCOa) verwendet.
Eine die besten Eigenschaften aufweisende Legierung wird durch nachstehendes Mischungsverhältnis erhalten :
EMI1.1
<tb>
<tb> Kupfer <SEP> 2-500 <SEP> kg
<tb> Mangankupfer.... <SEP> 1-250 <SEP> n
<tb> Zinn....... <SEP> 6-000 <SEP>

<tb> 10 <SEP> leg
<tb> auf <SEP> Aluminium <SEP> 90 <SEP> "
<tb>
Die Legierung besitzt, ohne spröde zu sein, die nötige Härte, dass sie beispielsweise sehr vorteilhaft auf Kochgeschirre, und zwar sowohl durch Guss wie aus Blech verarbeitet werden kann.

Process for the production of aluminum alloys.
Ataminium alloys, which in addition to aluminum also contain copper, tin, antimony and magnesium, are known per se; a typical alloy of this type is known from Austrian patent specification no. This alloy, which is easy to work with and extremely resistant to the influence of acids and oxidizing agents, has the disadvantage that it is too soft and therefore cannot be used in particular for cookware. The hardness of the alloy could certainly be increased by adding larger amounts of copper and antimony, but as the patent mentioned itself explains, this is only possible with an increase in brittleness, which is of course undesirable.
According to the present invention, part of the copper content is replaced by manganese copper in such a way that the amount of copper is approximately twice as large as the amount of manganese copper.
Potasche (RCOa) is advantageously used as a cleaning agent.
An alloy with the best properties is obtained by the following mixing ratio:
EMI1.1
<tb>
<tb> copper <SEP> 2-500 <SEP> kg
<tb> Manganese copper .... <SEP> 1-250 <SEP> n
<tb> tin ....... <SEP> 6-000 <SEP>
<tb> Antimony ..... <SEP> 01652 <SEP>
<tb> Magnesium .... <SEP> 0-0375 ,.
<tb>
Potache <SEP> 0-0375 Sulfur ... <SEP> 0-0125 "
<tb> 10 <SEP> leg
<tb> on <SEP> aluminum <SEP> 90 <SEP> "
<tb>
Without being brittle, the alloy has the necessary hardness so that it can be used, for example, very advantageously on cookware, both by casting and from sheet metal.
