Material EN AC-Al Si7Mg0,6 is produced as sand, chilled and precision casting. It shows the following casting characteristics and properties: plasticity: good heat crack resistance: excellent pressure tightness: good workability (casting condition): good corrosion resistance: good decorative anodic oxidation: insufficient weldability: good polishability: acceptable strength at room temperature: excellent strength at increased temp. (up to 200°C): acceptable ductility (impact strength): excellent fatigue strength amounts 80 to 110 N/mm² ( best available casting method, values for vibration durability up to 50*10 hoch 6 cycles [Woehler diagram]).
