Recently, the automobile industry need environmental standards and demands decrease of vehicle weight to reduce the environmental pollution. magnesium-Aluminum cast alloys are of commercial importance because of their various applications in the automotive industry. These alloys offer a combination of a high degree of achievable strength with excellent castability, light weight and good machinability with regard to both permanent molds and die castings forming. This paper show oxide distribution and deformation on casting condition of Mg elbow support. Moreover the microstructure of Mg elbow support is observed in the integrity assessment of porosity for nondestructive radiation x-ray.
