It shows the following casting characteristics and properties: plasticity: excellent heat crack resistance: excellent pressure tightness: excellent workability (after heat-treatment): acceptable (for Mg > 0,1 % applies classification good) corrosion resistance: good decorative anodic oxidation: not advisable weldability: excellent polishability: insufficient strength at room temperature: insufficient strength at increased temp. (up to 200°C): acceptable ductility (impact strength): excellent fatigue strength amounts 60 to 90 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-AlSi11, mat. No. 3.2211, acc. to DIN 1725-2 : 1986-02 applies: G-AlSi11 is an eutectic alloy of excellent form matching capability, high heat-crack resistance and excellent casting properties at high chemical resistance. It is suitable for complex, thin-walled, pressure-tight, vibration resistant casting parts at high corrosion resistance. Application: machine parts, cylinder heads and blocks, engine-, crank-, pump cases, blade wheels, assembly blocks and plates. |
