Definitions
- the present invention relates to a process for manufacturing articles of a zinc-based alloy containing aluminum and copper by centrifugal casting in a rubber mold or by pressure casting in a metal mold.
- a method of manufacturing articles of a zinc-based alloy containing aluminum and copper by centrifugal casting of this alloy in a rubber mold is described in the article "Rubber-mold spin-casting for low-cost prototype or production parts "by LS Schaer, Machine Design, January 20, 1977, p. 113-117.
- This known process uses either an alloy with 3.5% Al and 3.5% Cu, Zn residue, called “Formalloy”, or an alloy with 11% Al and 1% Cu, Zn residue, called “ILZRO-12” (all the percentages given in the present patent application are% by weight).
- Formalloy and ILZRO-12 have a solidification interval of 380-390 ° C and 380-432 ° C respectively and they are poured respectively at 393-427 ° C and 440-468 ° C.
- Formalloy has the drawback that its solidification starts with the formation of dendrites or basalts: these are liable to impede the circulation of the casting in the molding cavity and therefore risk causing casting defects.
- ILZRO-12 for its part requires a casting temperature of at least 440 ° C, which induces an accelerated deterioration of the silicone rubber of which the mold is made.
- Zamak alloys Center Technique du Zinc, PUBLIMAC, 92600, Asgnacs, November 1972.
- This known process uses an alloy with 3.9.-4.3% Al, 0.75-1.25% Cu and 0.03-0.06% Mg, Zn residue, called "Zamak 5".
- Zamak 5 presents, like Formalloy, a casting structure with a dendritic or basaltic tendency.
- the object of the present invention is to provide a method as defined above, which makes it possible to avoid the drawbacks of the known methods.
- the alloy contains 6.0-8.0% Al and 3.2-4.3% Cu, the rest being zinc, for example electrolytic zinc, and the impurities which are inevitably present in the aforementioned metals.
- the Cu content may not be less than 3.2% and greater than
- An Al content of less than 6.0% also produces a dendritic or basaltic structure, while an Al content of more than
- the alloy has excellent fluidity.
- an alloy with 6.7-7.3% of Al and 3.6-4.0% of Cu is used, and preferably an alloy having the eutectic composition: 7.0% of Al; 3.8% Cu and 89.2% Zn.
- the principle of this test is to "sink" by suction a liquid metal in a horizontal tube under a constant vacuum and a constant temperature, then to measure the length of sucked metal. This length is a measure for the flowability, that is, the fluidity, of the metal.
- Be alloy the "Superloy” alloy to which 0.005% of Be has been added and which will be called hereinafter "Be alloy"
- Zamak 3,387 381 4.04 0.001 0.043 0.0020 0.0021 0.0009 _
- Zamak 5 260 It is remarkable that the fluidity of Superloy is 43% higher than that of Zamak 2, which is itself the most fluid of Zamaks, but it is even more remarkable than the addition of only 0.005% of Be at Superloy is already reducing fluidity by 8%.
- the casting is carried out at a temperature which exceeds as little as possible, for example 5-30 ° C, the liquidus temperature of the alloy or the melting point in the case of the eutectic composition.
- the method of the invention is particularly useful for the manufacture of miniature cars by die casting.
