Abstract
An aluminum casting forged product is provided by using an aluminum alloy for casting forge including a useless raw material for forging such as flash as a raw material and by controlling a weight percentage of an alloy element such as silicon, magnesium, copper, and manganese; the product having an enhanced fluidity, and an improved castability, with retaining a sufficient strength, preventing useless intermetallic compounds from forming, restraining deterioration due to oxidation and corrosion, and further improved strength by a forging effect: and there is also provided a simple manufacturing method, with a high yield and high productivity. An aluminum casting forged product of high tensile strength, high proof, and elongation, higher mechanical properties than those of the conventional casting forged product, high corrosion resistance, and high quality without defects, and being low in cost is also obtainable as a thick-wall aluminum product.
