La présente invention concerne des alliages d'alu- The present invention relates to aluminum alloys
minium utilisables comme matières pour paliers, par exemple pour utilisation dans dels moteurs à combustion interne. Le brevet britannique N O 1 593 006 décrit un alliage aluminium/silicium/zinc comprenant 2 à 8 % en poids de silicium et 2 à 8 % de zinc avec des additions mineures They can be used as bearing materials, for example for use in internal combustion engines. British Patent No. 1,593,006 discloses an aluminum / silicon / zinc alloy comprising 2 to 8% by weight of silicon and 2 to 8% of zinc with minor additions
de plomb et de cuivre, le complément étant de l'aluminium. lead and copper, the balance being aluminum.
On pense que cet alliage peut avoir été développé à partir d'un alliage comprenant 1,5 % en poids de silicium et 5 % en poids de zinc, qui est utilisé dans la fabrication de It is believed that this alloy may have been developed from an alloy comprising 1.5% by weight of silicon and 5% by weight of zinc, which is used in the manufacture of
paliers pour vilebrequins en Allemagne. bearings for crankshafts in Germany.
Des alliages pour paliers du type aluminium-silicium- Bearing alloys of the aluminum-silicon type
zinc sont généralement coulés de manière continue, laminés et liés par laminage à de l'acier, de manière à produire une bande bimétallique à partir de laquelle on forme le palier pour vilebrequin L'opération de laminage est effectuée de préférence à froid, parce que le laminage à froid est une opération plus rapide et moins coûteuse que le laminage à chaud Toutefois, le laminage à froid des alliages décrits dans le brevet britannique N O 1 593 006 est difficile en ce qu'on observe qu'une fissutation importante dés bords se produit quand la teneur en silicium est voisine de l'extrémité supérieure de l'intervalle De plus, les alliages ayant une teneur en silicium proche de zinc are generally continuously cast, rolled and roll-bonded to steel, so as to produce a bimetallic strip from which the crankshaft bearing is formed. The rolling operation is preferably carried out cold, because Cold rolling is a faster and less expensive operation than hot rolling However, the cold rolling of the alloys described in British Patent No. 1,593,006 is difficult in that it is observed that a significant cracking of the edges occurs. when the silicon content is close to the upper end of the range. Moreover, alloys with a silicon content close to
l'extrémité inférieure de l'intervalle sont moins satis- the lower end of the interval are less satisfactory
faisants en ce qui concerne leurs propriétés dans les paliers quand la teneur en zinc est limitée à un maximum with regard to their properties in bearings when the zinc content is limited to a maximum
de 8 %.8%.
La présente invention a pour but de fournir un alliage aluminium/silicium/zinc ayant des caractéristiques The present invention aims to provide an aluminum / silicon / zinc alloy having characteristics
satisfaisantes pour les paliers, mais ayant des caracté- satisfactory for the bearings, but having characteristics

Selon l'invention, il est prévu un alliage comprenant de l à 4 % en poids de silicium et de 9 à il % en poids de -2- According to the invention, there is provided an alloy comprising from 1 to 4% by weight of silicon and from 9 to 11% by weight of
zinc, le complément étant de l'aluminium. zinc, the balance being aluminum.
On a trouvé qu'en limitant la teneur en silicium à un maximum de 4 % et en portant la teneur en zinc à 8-12 %, il n'y a pas de perte concernant les propriétés dans les paliers, mais on obtient un avantage considérable dans It has been found that by limiting the silicon content to a maximum of 4% and increasing the zinc content to 8-12%, there is no loss in bearing properties, but an advantage is obtained. considerable in
les caractéristiques de façonnage. the shaping characteristics.
En fait, on a trouvé que les alliages décrits dans la présente demande de brevet peuvent être laminés à froid dans une mesure bien plus grande que ceux décrits dans la technique antérieure sans une importante fissuration des bords On peut ainsi améliorer l'utilisation des matières, In fact, it has been found that the alloys described in this patent application can be cold rolled to a much greater extent than those described in the prior art without significant edge cracking. Thus, the use of the materials can be improved.
