Typical Mechanical Properties at Room Temperature
   

Mean values obtained from separately cast test bars produced in a cold chamber machine, using a multi cavity die. 6 mm round tensile test bars (L0=50 mm) and 10x10x50 mm impact test bars. Typical mechanical properties of die cast alloys are also listed in the standards (ISO, ASTM and En)
