Description

  

  Aluminium-Legierung.    Gegenstand vorliegender Erfindung ist  eine Aluminiumlegierung.  



  Zweck der Erfindung ist, eine Legierung  herzustellen, welche ein geringes spezifisches  Gewicht und gute Festigkeitseigenschaften  besitzt.  



  Die Aluminiumlegierung nach vorliegen  der Erfindung ist dadurch gekennzeichnet,  dass sie 1,1 bis 5,5% Kupfer, 2,0 bis 6,8%  Zink, 1,6 bis 5,0 % Magnesium, 0,02 bis 3,0  Eisen und 0,05 bis<B>1,0%</B> Silizium enthält,  wobei der Gehalt von Kupfer und Zink zu  sammen     9,75%    nicht überschreitet.  



  Diese Legierung kann geschmiedet, ge  walzt, gezogen, gepresst oder anderweitig  mechanisch     bearbeitet    werden.  



  Die Legierung kann noch einen oder meh  rere folgender Zusätze enthalten:  Nickel bis zu 3,5 % ; Mangan bis zu 2,0 % ;  Titan bis zu     1,011'o";        Antimon    bis zu<B>3,0%;</B>  Kobalt bis zu 2,5 %.  



  wenn irgend eines dieser fünf Elemente  vorhanden ist, so     wird    der Mag     nesiumgehalt       vorzugsweise auf 1,6 bis<B>2,5%</B> gehalten. Im  allgemeinen sollten diese Elemente in     einer     Menge von nicht über<B>1,5%</B> vorhanden sein,  aber für solche Zwecke, wo eine harte Ober  fläche nötig ist, wie zum Beispiel für Zylin  derfutter von     Verbrennungsmaschinen,    sollte  eines oder mehrere dieser Elemente vorhan  den sein, sei es zum oben     angegebenen    Pro  zentsatz oder zu     einem    die Hälfte dieses an  gegebenen Gehaltes     übersteigenden    Prozent  satz. In keinem Fall sollten mehr als 4  als Gesamtmenge dieser Elemente vorhanden  sein.  



  Normalerweise sollte nicht mehr als  <B>0,38%</B> Mangan vorhanden sein, aber falls  mehr als<B>2,5%</B> Magnesium oder mehr als  2,5 % Kupfer vorhanden sind, dann kann der       Mangangehalt    bis zu 2 % betragen.  



  Neben den vorerwähnten fünf Elementen  Nickel, Mangan, Antimon, Kobalt und Titan  kann auch Beryllium, Chrom, Silber,     Molyb-          dän,    Zinn, Blei, Wolfram,     Vanadium,    Bor,       Zirkonium,        Cerium,        Thorium    oder     Lithium         bis zu einem Gehalt von 2     %    vorhanden sein,  ohne wesentlich die von der Erfindung er  strebten Resultate zu beeinträchtigen.  



  Andere Elemente, wie     Kadmiun,    Cal  cium, Wismut. Arsen, Natrium und Kalium,  dürfen vorhanden sein, sei es, weil sie in den  zur Herstellung der Legierung verwendeten  Metallen schon     enthalten    sind, oder weil sie  gebraucht werden im     Reinigungs-    und     Ent-          gasungsprozess    der geschmolzenen Legierung.  Diese und andere Verunreinigungen sollten  0,5 % nicht überschreiten.  



  Die Legierung kann in üblicher Weise  hergestellt werden, nämlich durch Beigabe  zu geschmolzenem, im Handel vorkommen  den Aluminium von an einem oder zwei der  zuzufügenden Elemente reichen     Aluminium-          legierungen.    Gewisse Elemente, wie Zink  und Magnesium können in     fester    Form zum  flüssigen, die andern Elemente enthaltenden  Guss, zugegeben werden.  



  Die Legierung kann eine Hitzebehandlung       erfahren.    Die bevorzugte Form der Hitze  behandlung besteht darin, dass man den Guss  auf einer Temperatur von 410 bis 480' C  eine halbe Stunde lang hält und dann in  Wasser abschreckt, worauf eine künstliche       Alterungsbehandlung    folgt, welche weiter  unten als Härtung erwähnt wird, bei 120 bis  <B>180</B>   C während 6 bis 24 Stunden, und dann  an der Luft oder im Wasser erkalten lässt.

         Beispiele:     Eine Legierung folgender Zusammenset  zung     wurde    von einem     91/2    cm Durchmesser  haltenden     Gussblock    in eine quadratische       Stange    von 2,5 cm geschmiedet:  Kupfer<B>2,7%;</B> Magnesium 2,2%; Zink  <B>6,2%;</B> Eisen 0,2%; Silizium     0,2%;    Titan  <B>0,05%;</B> Rest. Aluminium.  



  Nach dem Abschrecken von 470' C und  Härten bis 140' C während 10 Stunden er  hielt man folgende physikalische Eigenschaf  ten für Stangen, welche bis auf 12 mm  Durchmesser bearbeitet wurden:  Maximale Zugfestigkeit 58.28 kg pro mm',  Streckgrenze 50,40 kg pro mm', Dehnung    <B>15,0%,</B>     Querschnittsverminderung   <B>25,9%,</B>       Brinellhärte    180, spezifisches Gewicht<B>2,81.</B>  



  Eine Legierung von geringerem spezifi  schem     Gewicht    wurde     aus    folgender Mi  schung erhalten:  Kupfer     2,25%;    Zink 4,0%;     Magnesium          3,0%;    Nickel 0,4%; Eisen     0,2%;    Silizium  <B>0,18%;</B> Rest Aluminium.  



  Nach dem Abschrecken von 480' C und  Härten bei 140' C während 16 Stunden er  hielt man die folgenden     Festigkeitswerte:     Maximale Zugfestigkeit 58,44 kg pro mm',       Streckgrenze    50,2 kg pro mm', Dehnung 13     %,          Querschnittsverminderung    23,0     %,        Brinell-          härte    176, spezifisches Gewicht 2,78.  



  Andere passende     Legierungsverhältnisse     sind die folgenden:  Kupfer 2,2 bis 2,9     %    ; Eisen nicht über  <B>0,3%;</B> Magnesium 2,8 bis<B>3,2%;</B> Silizium  nicht     über   <B>0,3%;</B> Titan 0,1 bis     0.,18%;    Zink  4.5 bis 4,9%; Rest Aluminium, und:  Kupfer 1,8 bis     2,25%;    Eisen nicht über  <B>0,3%;</B>     Magnesium    2,1 bis 2,5%; Silizium  nicht über<B>0,3%;</B> Zink 5,75 bis<B>6,5%;</B> Rest       Aluminium.     



  Die angegebenen Prozente sind überall  Gewichtsprozente. Die durch die Legierung  erhaltenen Vorteile sind ein geringes spezifi  sches Gewicht bei guten Festigkeitsverhält  nissen, leichte     Bearbeitung    und weite Gren  zen für das Schmieden und die Hitzebehand  lung. Die Festigkeit in heissem Zustand ist  sehr vom Prozentsatz des vorhandenen Zinks  abhängig. Zum Beispiel kann eine 4 % Zink  enthaltende Legierung bei einer um 20 bis  40   C höheren Temperatur geschmiedet und  heiss behandelt werden, als eine Legierung  mit 6     %    Zink.  



  Die Legierung hat eine     gute    Korrosions  festigkeit und leidet nicht durch Kornwachs  tum.  



  Sie verhält sich auch gut gegen Er  müdung bei Temperaturen von 100   C und  darüber, wodurch die Legierung für Pleuel  stangen von Verbrennungsmaschinen ver  wendbar     wird;    auch ist das Verhältnis zwi  schen     Zugfestigkeit    und spezifischem Ge  wicht ein     günstiges.         Die Legierung ist besonders verwendbar  für Teile von     Verbrennungsmaschinen    und  von Kraftfahrzeugen, ist aber nicht hierauf  beschränkt.

   Sie ist auch verwendbar für  Ketten, Supporte, Gitter, Maschinengestelle,  Riemenscheiben,     Rohre,    Achsen     und        Press-          artikel    für     Kraftwagen,    wie zum Beispiel       Spritzbretter.     



  Die Zeitdauer für das Härten oder An  lassen beträgt vorzugsweise 6 bis 24 Stunden.  Für geschmiedete     Kurbelkästen    und La  gerdeckel ist folgende     Legierung    vorteilhaft:  Kupfer 1,7 bis 2,0%; Zink 4,2 bis 4,5%;  Magnesium 2,2 bis<B>2,5%;</B>     Titan    0,05 bis  <B>0,15%;</B> Eisen     unter   <B>0,25%;</B> Silizium unter  0,25%; Rest Aluminium.  



  Die bevorzugte     Hitzebehandlung    besteht  in einem Abschrecken von 450 bis 480' C  und einem Anlassen bei 120 bis<B>160'</B> C.

  Aluminum alloy. The present invention relates to an aluminum alloy.



  The purpose of the invention is to produce an alloy which has a low specific weight and good strength properties.



  The aluminum alloy according to the present invention is characterized in that it contains 1.1 to 5.5% copper, 2.0 to 6.8% zinc, 1.6 to 5.0% magnesium, 0.02 to 3.0% iron and 0.05 to 1.0% silicon, the content of copper and zinc together not exceeding 9.75%.



  This alloy can be forged, rolled, drawn, pressed or otherwise mechanically processed.



  The alloy can also contain one or more of the following additives: nickel up to 3.5%; Manganese up to 2.0%; Titanium up to 1.011'o "; Antimony up to <B> 3.0%; </B> Cobalt up to 2.5%.



  when any of these five elements are present, the magnesium content is preferably kept at 1.6 to 2.5%. In general, these elements should be present in an amount not exceeding 1.5%, but for purposes where a hard surface is required, such as cylinder liners for internal combustion engines, one or Several of these elements may be present, either at the percentage given above or at a percentage that exceeds half of the given content. In no case should there be more than 4 total of these elements.



  Normally there should be no more than 0.38% manganese, but if there is more than 2.5% magnesium or more than 2.5% copper then the Manganese content can be up to 2%.



  In addition to the above-mentioned five elements nickel, manganese, antimony, cobalt and titanium, beryllium, chromium, silver, molybdenum, tin, lead, tungsten, vanadium, boron, zirconium, cerium, thorium or lithium up to a content of 2% can be used. be present without significantly affecting the results sought by the invention.



  Other elements such as kadmiun, calcium, bismuth. Arsenic, sodium and potassium may be present, either because they are already contained in the metals used to manufacture the alloy, or because they are needed in the cleaning and degassing process of the molten alloy. These and other impurities should not exceed 0.5%.



  The alloy can be produced in the usual way, namely by adding to molten aluminum, commercially available aluminum alloys rich in one or two of the elements to be added. Certain elements such as zinc and magnesium can be added in solid form to the liquid cast containing the other elements.



  The alloy can be heat treated. The preferred form of heat treatment is to hold the casting at a temperature of 410 to 480 ° C for half an hour and then quench it in water, followed by an artificial aging treatment, which is mentioned below as hardening, at 120 to <B> 180 </B> C for 6 to 24 hours, and then let it cool in the air or in water.

         Examples: An alloy of the following composition was forged from a cast block with a 91/2 cm diameter into a square bar of 2.5 cm: copper 2.7%; magnesium 2.2%; Zinc 6.2%; iron 0.2%; Silicon 0.2%; Titanium <B> 0.05%; </B> balance. Aluminum.



  After quenching at 470 ° C and hardening to 140 ° C for 10 hours, the following physical properties were obtained for rods which were machined to a diameter of 12 mm: Maximum tensile strength 58.28 kg per mm ', yield point 50.40 kg per mm ', Elongation <B> 15.0%, </B> cross-section reduction <B> 25.9%, </B> Brinell hardness 180, specific weight <B> 2.81. </B>



  An alloy with a lower specific weight was obtained from the following mixture: copper 2.25%; Zinc 4.0%; Magnesium 3.0%; Nickel 0.4%; Iron 0.2%; Silicon <B> 0.18%; </B> the remainder aluminum.



  After quenching at 480 ° C. and hardening at 140 ° C. for 16 hours, the following strength values were obtained: maximum tensile strength 58.44 kg per mm ', yield point 50.2 kg per mm', elongation 13%, cross-sectional reduction 23.0 %, Brinell hardness 176, specific weight 2.78.



  Other suitable alloy ratios are as follows: copper 2.2 to 2.9%; Iron not more than <B> 0.3%; </B> Magnesium 2.8 to <B> 3.2%; </B> Silicon not more than <B> 0.3%; </B> Titanium 0, 1 to 0.18%; Zinc 4.5 to 4.9%; Balance aluminum, and: copper 1.8 to 2.25%; Iron not more than <B> 0.3%; </B> magnesium 2.1 to 2.5%; Silicon not more than <B> 0.3%; </B> zinc 5.75 to <B> 6.5%; </B> the remainder aluminum.



  The percentages given are all percentages by weight. The advantages obtained by the alloy are a low specific weight with good strength ratios, easy machining and wide limits for forging and heat treatment. The strength when hot is very dependent on the percentage of zinc present. For example, an alloy containing 4% zinc can be forged and hot treated at a temperature 20 to 40 C higher than an alloy with 6% zinc.



  The alloy has good corrosion resistance and does not suffer from grain growth.



  It also behaves well against fatigue at temperatures of 100 C and above, making the alloy rods for connecting rods of internal combustion engines ver usable; the relationship between tensile strength and specific weight is also favorable. The alloy is particularly useful for parts of internal combustion engines and automobiles, but is not limited thereto.

   It can also be used for chains, supports, grids, machine frames, pulleys, tubes, axles and press articles for motor vehicles, such as spray boards.
