Recent Developments in Impact, Flexural and Fatigue Data for Zinc Die Casting Anti-Theft Applications 2011-01-1088

Alloy 3, Alloy 5, ACuZinc 5, and ZA-8 were tested at five temperatures between −40 C and room temperature to determine impact properties. Izod impact energy data was obtained in accordance with ASTM D256. Unlike ASTM E23, these samples were tested with a milled notch in order to compare with plastic samples. In addition, flexural data was obtained for design use. Fatigue stress-life (S-N) curves and fatigue limits of die cast zinc Alloy 2, Alloy 3, Alloy 5, ACuZinc 5, and ZA-8 were determined using the rotating bend test. Fatigue limits for Alloy 3, Alloy 5, and ACuZinc 5 appeared to be higher and the fatigue limit for ZA-8 appeared to be lower than the values reported in the literature. The improvement in properties for Alloy 3, Alloy 5 and ACuZinc 5 is related to the presence of the die cast skin.
