摘要： Heat resistant Al die cast material having 12.5% to 14.0% of Si, 3.0% to 4.5% of Cu, 1.4% to 2.0% of Mg, and 1.12% to 2.4% of Zn. The die cast metal becomes amenable to age hardening treatment when appropriate amounts of Mg and Zn are added to an Al—Si—Cu alloy for enhancing mechanical strength and seizure characteristics.

摘要： The coating structure having a corrosion resistance of the invention contains a formation film formed on the surface of an aluminum alloy material. The formation film is subjected to a zirconium phosphate treatment. Because the zirconium phosphate reacts with an oxide film on the surface of the aluminum alloy to form a zirconium boehmite layer and to increase the adhesion of the coating material, a corrosion resisting structure is obtained without need of a sealing treatment while restraining the increase of the product cost. Also, a primer layer is formed on the outer surface of the formation film and the primer layer is composed of phosphomolybdic acid.

摘要： A molten metal is poured into and stored in a hopper in a rotary-mold gravity casting process, so that a small amount of the molten metal is allowed to flow out of the hopper into a runner to previously fill up the runner. A casting mold is rotated from this state, thereby causing the molten metal to be filled from the hopper into a cavity by a difference in height generated between the molten metal level in the hopper and the molten metal level in the casting mold. Thus, when the molten metal, once stored in the hopper, is filled into the cavity in the casting mold by rotating the casting mold, the inclusion of air can be prevented from being produced due to ruffling of the molten metal in the cavity.

摘要： A process for forming an improved anodizing film on the surface of an aluminum alloy material. The film is impregnated with an amorphous substance which fills pores formed in the film during its growth. If the film has a flaw reaching the aluminum alloy material, the amorphous substance and aluminum form a layer of passivity which restrains the corrosion of the aluminum alloy material.

摘要： A novel aluminum die-cast material having all good properties of high fluidity, good corrosion resistance and high mechanical strength is disclosed. As its Mg content, a factor to increase mechanical strength, is increased to fall between 0.4 and 0.6% by weight, the material has good mechanical properties. As its Cu content, a factor to cause corrosion, is reduced to at most 0.15% by weight, the material has good corrosion resistance to seawater. As its Si content, a factor to increase casting fluidity, is increased to fall between 10.0 and 11.5% by weight, the material has good fluidity.
