Material EN AC-AlSi10Mg(a) is produced as sand and chilled cast. It shows the following casting characteristics and properties: plasticity: excellent heat crack resistance: excellent pressure tightness: good workability (after heat-treatment): good to acceptable workability (casting condition): good corrosion resistance: acceptable decorative anodic oxidation: not advisable weldability: excellent polishability: acceptable strength at room temperature: good strength at increased temp. (up to 200°C): acceptable ductility (impact strength): acceptable 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-AlSi10Mg(Cu), mat. No. 3.2383, acc. to DIN 1725-2 : 1986-02 applies: The material is a neareutectic alloy of favorable casting properties. Its weldability is excellent. It is suitable for complex, thin-walled, pressure-tight, vibration resistant, impact loaded casting parts. Application: Vehicle, machine, equipment and apparatus engineering cases, finned bodies, brake pads.
