1) Remark: Material EN AC-AlSi7Mg0,3 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]). To the comparable DIN-mark G-AlSi7Mg, mat. No. 3.2371, acc. to DIN 1725-2 : 1986-02 applies: The material is a multipurpose alloy of favorable mechanical properties, high strength and ductility as well as high corrosion resistance. Weldability is excellent. Application: Casting parts for vehicle, machine and aircraft industry, shipbuilding and electrical engineering.
