Embodiment Construction

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0040] One aspect of the present invention relates to an aluminum alloy, which is composed of silicon (Si), iron (Fe), magnesium (Mg), nickel (Ni), titanium (Ti), tin (Sn), and the remainder aluminum (Al). Aluminum alloy for die casting in order to achieve high strength with high corrosion resistance and high thermal conductivity at the same time.

[0041] Silicon (Si) improves fluidity and strength, and is preferably included in the range of 5.0 to 7.0 weight percent relative to the total weight of the alloy. That is, if silicon is more than 7.0% by weight, the heat treatment is poor and may be broken, and if it is less than 5.0% by weight, the original purpose cannot be achieved. Therefore, it is most preferable to include 6.0 weight percent so that both fluidity and strength and heat treatment can be improved.

Abstract

One aspect of the present invention relates to an aluminum alloy for high strength die casting with excellent corrosion resistance and thermal conductivity, comprising, based on total weight, 5-7 wt%of silicon (Si); 0.1-1.0 wt% of iron (Fe); 1.0-3.0 wt% of magnesium (Mg); 0.1-1.0 wt% of nickel (Ni); 0.15-0.45 wt% of titanium (Ti); 1.0-3.0 wt% of tin (Sn); and the remaining amount of aluminum (Al).

Description

technical field [0001] The present invention relates to an aluminum alloy for die-casting, a method for producing the same, and a method for producing a cast product using the aluminum alloy for die-casting, and more particularly, to an aluminum alloy that exhibits excellent corrosion resistance and heat release, and high thermal conductivity and tensile strength High-strength aluminum alloy for die-casting with excellent corrosion resistance and thermal conductivity and its manufacturing method and use A method for manufacturing aluminum alloy castings. Background technique [0002] In general, there are two methods of manufacturing products from aluminum: the firing method, in which an aluminum plate is extruded to produce a desired shape; the die-casting method, in which molten aluminum is injected into a mold that is machined in the shape of the product , making the same casting as the mold. [0003] Products produced by die-casting have the advantage of correct dimens...
