PURPOSE:To provide an aluminum die casting product, which anode oxidation treatment can be easily and surely executed, by setting the whole area of the surface of the die casting product and the whole volume of the product to the specific relation. CONSTITUTION:The Si series aluminum die casting product is constituted by condition of 6>=X/Y>=1 at the time of using X mm<2> for the whole area aud Y mm<3> for the whole volume. By this method, the anode oxidation can be uniformly, easily and surely executed over the whole surface of the Si series die casting product.
