Definitions

  • the invention relates to an aluminum alloy for die casting of components with high elongation in the cast state.
  • the die casting technology has developed so far today that it is possible to produce components with high quality standards.
  • the quality of a die casting depends not only on the machine setting and the chosen process, but also to a great extent on the chemical composition and the microstructure of the aluminum alloy used. These two latter parameters are known to influence the castability, the feeding behavior ( G. Schindelbauer, J. Czikel “Shape Fillability and Volume Deficit of Usual Aluminum Die Casting Alloys", foundry research 42, 1990, p. 88/89 ), the mechanical properties and - most importantly during diecasting - the lifetime of the casting tools (LA Norström, B. Klarenfjord, M. Svenson “General Aspect on Wash-out Mechanism in Aluminum Diecasting Dies", 17th International NADCA Diecasting Congress 1993 , Cleveland OH).
  • the die-cast parts In order that the required mechanical properties, in particular a high elongation at break, can be achieved, the die-cast parts usually have to be subjected to a heat treatment.
  • This heat treatment is necessary for the molding of the casting phases and thus for achieving a tough breaking behavior.
  • a heat treatment usually means a solution annealing at temperatures just below the solidus temperature with subsequent quenching in water or another medium to temperatures ⁇ 100 ° C.
  • the material thus treated now has a low yield strength and tensile strength.
  • a thermal aging is then carried out. This can also be done by the process, e.g. by thermal application during painting or by stress-relief annealing of an entire group of components.
  • die castings are cast close to the final dimensions, they usually have a complicated geometry with thin wall thicknesses.
  • delays have to be expected, such as reworking, e.g. by directing the castings or, in the worst case, rejects.
  • the solution annealing also causes additional costs and the economics of this production method could be significantly increased if alloys were available which meet the required properties without a heat treatment.
  • An AlSi alloy with good mechanical values in the as-cast state is from the EP-A-0 687 742 known. Also, for example, from the EP-A-0 911 420 Alloys of the type known AIMg, which have a very high ductility in the cast state, but in complicated shape design tend to hot or cold cracks and are therefore unsuitable.
  • Another disadvantage of ductile die-cast alloys is their slow aging in the cast state, which causes a temporal change in the mechanical properties, including a loss of elongation. can result. This behavior is tolerated in many applications, since the property limits are not exceeded or fallen below, but is not tolerable in some applications and can only be turned off by a targeted heat treatment.
  • the invention has for its object to provide a suitable die-casting aluminum alloy, which is very easy to cast, has a high elongation in the cast state and no longer ages after casting.
  • the alloy should be well weldable and crimpable, can be riveted and have a high corrosion resistance.
  • the object is achieved by an aluminum alloy with 8.5 to 10.5 wt .-% silicon 0.3 to 0.8% by weight of manganese Max. 0.06 wt .-% magnesium Max. 0.15% by weight of iron Max. 0.03 wt .-% copper Max. 0.10% by weight of zinc Max.
  • the alloy composition according to the invention With the alloy composition according to the invention, a high elongation can be achieved in the case of cast parts in the cast state with good values for the yield strength and the tensile strength, so that the alloy is particularly suitable for the production of safety components in the automotive industry. Surprisingly, it has been found that by adding molybdenum, the elongation can be increased again without loss of the other mechanical properties.
  • the desired effect is achieved with an addition of 0.05 to 0.5 wt .-% Mo, the preferred content is 0.08 to 0.25 wt .-% Mo.
  • the elongation can be even further improved.
  • the preferred content is 0.15 to 0.20 wt% Zr.
  • the relatively large proportion of eutectic silicon is refined by strontium. Compared to granular die-cast alloys with higher impurities, the alloy according to the invention also has advantages in terms of fatigue strength.
  • the fracture toughness is higher due to the very small present mixed crystals and the refined eutectic.
  • the strontium content is preferably between 50 and 150 ppm and should generally not fall below 50 ppm, since otherwise the casting behavior can be worsened. Instead of strontium, sodium and / or calcium may be added.
  • the limitation of the magnesium content to preferably max. 0.05% by weight of Mg causes the eutectic structure not to be coarsened and the alloy has no curing potential, which contributes to high elongation.
  • the proportion of manganese prevents sticking in the mold and ensures good mold release.
  • the manganese content gives the casting a high structural strength at elevated temperature, so that with demolding with very little to no distortion is to be expected.
  • the alloy according to the invention can be riveted in the cast state.
  • the alloy according to the invention is preferably produced as a horizontal continuous casting ingot.
  • a die-cast alloy with low oxide contamination can be melted without expensive melt cleaning: an important prerequisite for achieving high elongation values in the die-cast part.
  • the purification of the inventive time-refined AlSi alloy is preferably carried out by means of a purge gas treatment with inert gases by means of an impeller.
  • Grain refining is preferably carried out in the case of the alloy according to the invention.
  • the alloy gallium phosphide and / or indium phosphide in an amount corresponding to 1 to 250 ppm, preferably 1 to 30 ppm of phosphorus can be supplied.
  • the alloy for grain refining may also contain titanium and boron, the addition of titanium and boron via a master alloy with 1 to 2% by weight of Ti and 1 to 2% by weight of B, balance aluminum.
  • the aluminum master alloy contains 1.3 to 1.8% by weight of Ti and 1.3 to 1.8% by weight of B, and has a Ti / B weight ratio of about 0.8 to 1.2.
  • the content of the master alloy in the alloy of the present invention is preferably adjusted to 0.05 to 0.5% by weight.
  • the aluminum alloy according to the invention is particularly suitable for the production of safety components in diecasting.
