Description

  

      Vergütbare    Leichtmetall-Legierung     und    Verfahren zu deren     Herstellung       Vorliegende     Erfindung    betrifft eine     ver-          gütba.re        Leichtmetall-Legierung,    die folgende  Zusammensetzung aufweist         Cu        0,9-1,70/0.          Si    6,3-6,7 0/0       Mg        0,2-0e4%          Mn0,2-0,7        %          Fe        0,4-1,8%     Rest Aluminium.

      Diese     vergütbare        Leichtmetall-Legierung     hat den Vorteil,     da:ss        sie    sieh für sehr kom  plizierte und     giesstechniseh    sehr schwierig zu       vergiessende        Gussteile    eignet.  



  Mit dieser     vergütbaren    Leichtmetall Legie  rung können     Festigkeitswerte    bis ungefähr  35     kg/mm2    mit einer Dehnung bis     3,51/o     sowie     Brinellhärten    bis 130     kglmm2    erzielt  werden. Schon im     unvergüteten    Zustand       können        Brinellhärten    von 80     kg/mm2    erreicht.  werden..  



  Die     erfindungsgemässe    Legierung     besitzt     auch einen besonders     guten    Widerstand     ge-          (ren    Verschleiss.  



  Weiterhin hat die     vergütbare        Leichtme-          tall-Legierung    besondere Vorteile hinsicht  lich ihrer mechanischen     Bearbeitbarkeit,     indem auf sämtliche bisher erforderliche Zu  satzmittel, wie Terpentin und dergleichen,  verzichtet werden kann.  



  Die Herstellung der erfindungsgemässen  Legierung erfolgt     zweckmässig    derart,     dass          die        Leiehtmetall-Legierung    unter Verwen-         dune    einer     Vorlegierung    aus gleichen Ge  wichtsteilen Kupfer und Aluminium er  schmolzen wird, wobei die höher     schmelzen-          den    Bestandteile zuletzt     zugesetzt    werden.  



       Aus   <I>f</I>     ührungsbeispieZ     Aus gleichen     Gewiehtsteilen        Aluminium     und Kupfer wird eine     Vorlegierung    erzeugt,       indem.    in geschmolzenes Aluminium (rein)  die gleiche     Gewiehtsmenge    Kupfer eingetra  gen wird.

      Heat treatable light metal alloy and process for its production The present invention relates to a heat treatable light metal alloy which has the following composition Cu 0.9-1.70 / 0. Si 6.3-6.7 0/0 Mg 0.2-0e4% Mn0.2-0.7% Fe 0.4-1.8% balance aluminum.

      This heat treatable light metal alloy has the advantage that it is suitable for very complicated cast parts that are very difficult to cast in terms of casting technology.



  With this heat treatable light metal alloy, strength values of up to about 35 kg / mm2 with an elongation of up to 3.51 / o and Brinell hardnesses of up to 130 kg / mm2 can be achieved. Brinell hardnesses of 80 kg / mm2 can be achieved even in the non-tempered state. will..



  The alloy according to the invention also has a particularly good resistance to wear.



  Furthermore, the heat treatable light metal alloy has particular advantages with regard to its mechanical workability, in that all the additives previously required, such as turpentine and the like, can be dispensed with.



  The alloy according to the invention is expediently produced in such a way that the light metal alloy is melted using a master alloy composed of equal parts by weight of copper and aluminum, with the higher-melting components being added last.



       FROM <I> f </I> EXAMPLE A master alloy is produced from the same weighted parts aluminum and copper by. The same weight of copper is entered in molten aluminum (pure).
