Definitions
- the invention relates to an aluminum casting alloy, in particular an aluminum die casting alloy.
- Die casting technology has developed so far today that it is possible to cast pieces to manufacture with high quality requirements.
- the quality of a die casting depends not only on the machine setting and the chosen method, but also to a large extent on the chemical composition and structure the cast alloy used. These two latter parameters are known to influence the pourability, the feeding behavior (G. Schindelbauer, J. Czikel “Mold filling capacity and volume deficit of common aluminum die casting alloys” Foundry Research 42, 1990, pp. 88/89), the mechanical Properties and - particularly important in die casting - the service life the casting tools (L.A. Norström, B. Klarenfjord, M. Svenson "General Aspects on Wash-out Mechanism in Aluminum Diecasting Dies ", 17th International NADCA Diecasting Congress 1993, Cleveland OH).
- AIMg alloys are also known which are distinguished by a high ductility. Such an alloy is disclosed, for example, in US-A-5 573 606. However, these alloys have the disadvantage of high mold wear and cause molding problems, which significantly reduces productivity.
- WO-A-9625528 are die-cast alloys made of aluminum known with the essential alloying elements magnesium, manganese and silicon.
- the present invention is therefore based on the object of providing a die-casting alloy with a high elongation at break with an even acceptable yield strength, which has good castability and sticks as little as possible in the mold.
- the following minimum values must be achieved in the as-cast state: Elongation (A5): 14% yield strength (Rp 0.2): 100 MPa
- the alloy should also be easy to weld, a high corrosion resistance and in particular show no susceptibility to stress corrosion cracking.
- the one used to make the alloy The degree of purity of the aluminum corresponds to a smelting aluminum quality Al 99.8 H.
- This alloy has a well molded ⁇ phase in the as-cast state.
- the eutectic mainly consisting of Mg 2 Si and Al 6 Mn phases, is very fine and therefore leads to a highly ductile fracture behavior.
- the manganese content prevents sticking in the mold and ensures good mold release.
- the magnesium content in connection with manganese gives the casting a high level of design stability, so that very little or no distortion can be expected even when demolding
- this alloy can also be used for Use thixocasting or thixo forging.
- the ⁇ phase forms when it melts again immediately, so that excellent thixotropic properties are available.
- the iron content is kept as deep as possible in the alloy.
- the alloy composition according to the invention despite low Iron content does not tend to stick in the mold Contrary to popular belief that with high iron contents, sticking in the mold is prevented in any case has been found in the alloy type proposed according to the invention, that when the iron content is increased to more than 0.4% by weight again an increase in the tendency to stick is observed.
- the following content ranges are preferred for the individual alloy elements: magnesium 2.5 to 3.3% by weight, in particular 2.6 to 3.3% by weight Silizum 0.20 to 0.30% by weight manganese 0.40 to 1.2% by weight, in particular 0.50 to 1.0% by weight iron Max. 0.30% by weight, in particular max. 0.15% by weight
- the alloy therefore contains 0.10 to 0.60 % By weight, in particular 0.30 to 0.60% by weight of cobalt and / or 0.05 to 0.80% by weight, in particular 0.10 to 0.50% by weight of cerium.
- An optimal effect is achieved if the sum of the cobalt, cerium and manganese contents in the alloy at least Is 0.80% by weight and the alloy contains at least 0.50% by weight of manganese.
- the aluminum casting alloy according to the invention is particularly suitable for this Thixocasting or thixo forging.
