This is a division of application Ser. No. 85,372, filed Oct. 30, l970, now US. Pat. No. 3,726,672. 5
This inventionrela tes to an aluminum base alloy having high strength, excellent die-casting characteristics, excellent machinabilityv and superior mechanical properties. It is especially useful for the die casting of automobile wheels, although its application is not so limited.
With the advent ofa keen interest in the use of lightweight aluminum base alloys for articles which must stand the abuse and stresses heretofore reserved for ferrous metals and alloys, it became important to develop improved aluminum base alloys for such products. However, to be maximally useful for automobile wheels and other such products, aluminum base alloys had to be die-castable, corrosion'resistant, readily machinable and of a higher strength than those aluminum base alloys previously available and at a-lower cost than other available alloys having comparable properties.
Although aluminum base die-cast alloys have been on the market for many years where lightweight, accuratedimensioning and the like was important, generally those alloys were not suitable for use in applications where substantial abuse and high stresses were-encountered.
- The only alloy which met with limited successin, and
which has properties generally suitable for high stress applications, such as in die-cast automobile wheels, is one known to the trade as 364 alloy. This is made generally in accordance with Blackmun US. Pat. No. 2,823,995. Although that alloy improved upon prior art alloys in certain respects, the properties of that alloy were not as good as was'desirable. Furthermore, the cost of that alloy was too high 'for general use. Consequently, insofar as aluminum base alloy die cast automobile wheels were concerned, that alloy was used only for highcost specialty wheels.
in accordance with this invention an aluminum base die-casting alloy having substantially improved mechanical properties is provided. lts cost is substantially lower than the cost of the 364 alloy previously used for similar purposes, and indeed scrap aluminum and other secondary aluminum available for secondary reformulation, rather than primary aluminum, may be used to compound the alloy of this invention. As such, the alloy ofthis invention provides the commercial potential, for
by weight'of the final alloy, 0.25 to 0.6% magnesium; 0.25 to 06% copper; 0.5 to l.5% iron; ll to l3.5% silicon; and 0.25 to 0.4% chromium. The high silicon content and the copper content substantially contribute, we believe, in combination with the other ingredients to the superior physical properties of this alloy.
The composition 'of this invention which maximizes the characteristics and properties of die-cast products. such as automobile wheels, while minimizing the costs attendant the manufacture anduse of the alloy composition, consists essentially of aluminum. and by weight of the final alloy, 0.25 to 0.6% magnesium. 0.25 to 0.6% copper, 0.5 to l.5% iron, ll to. 13.5% silicon, 0.25 to 0.4% chromium, a maximum of 3% zinc, a maximum of 0.5% manganese, and a maximum of 0.2% each of titanium, nickel, tin and lead. Die-cast products such as automobile wheels cast of this alloy have an overall combination of impact strength, fatigue strength, tensile strength, yield strength and ductility characteristics which is superior to those of other aluminum base die-casting compositions of which we are aware, including those characteristics available in products die-cast from 364 alloy. Furthermore, the corrosion resistance and machinability of wheels die-cast of this alloy-are quite excellent andthe die-casting characteristics are as good as any aluminum alloy available for the high stress applications for which the alloy of this invention is useful.
Although the advantages of this invention may beobtained within the aforementioned ranges, we have deter'mined that an especially useful preferred range of ingredients is a composition consisting essentiallyof aluminum, and by weight of the final composition 0.25
to 0.4% magnesium, 0.25 to 0.5% copper, 0.4 to 0.8% iron, 1 l to 12% silicon, 0.3 to 0.4% chromium, a maximum of 1% zinc, a maximum of 0.35% manganese, a maximum of 0.05% of each of titanium and nickel, and a maximum of 0.1% of each of tin and lead.
FIGS. 1 and 2 illustrate typical automobile wheels which have been die-cast with aluminum base alloys.
Die-cast automobile wheels have been made from aluminum base alloys of this invention, as well as from a commercially available 364 alloy. Several such' wheels have been analyzed to determine their final composition. Further, those wheels have been tested for yield strength, tensile strength and ductility.
