description | PROBLEM TO BE SOLVED: To provide a magnesium alloy material with excellent corrosion resistance.SOLUTION: The magnesium alloy material comprises a magnesium alloy containing 7.3 mass%-16 mass% Al, and is representatively a coil material formed by winding a long-length plate material. When the Al content of the whole magnesium alloy material is x mass%, the area with the Al content of 0.8x mass%-1.2x mass% is 50 area% or more, the area with the Al content of 1.4x mass% or more is 17.5 area% or less and there is substantially no area with the Al content of 4.2 mass% or less. In the magnesium alloy material, since the variation of Al concentration is low and there are few areas with extremely low Al content, the occurrence of localized corrosion and the progression of the corrosion are effectively prevented. Thus, the magnesium alloy material has excellent corrosion resistance compared to a die cast material with the same overall Al content. |
