Abstract
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.
