EN AC-44200 (DIN EN 1706 : 1998-06) EN AC-44200 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany G-AlSi12 EN AC-Al Si12(a) 2.1 1)
1) Remark: Material EN AC-AlSi12(a) is produced as sand and chilled cast. It shows the following casting characteristics and properties: plasticity: excellent heat crack resistance: excellent pressure tightness: excellent workability (after heat-treatment): acceptable corrosion resistance: good decorative anodic oxidation: not advisable weldability: excellent polishability: insufficient strength at room temperature: insufficient strength at increased temp. : 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-AlSi12, mat. No. 3.2581, acc. to DIN 1725-2 : 1986-02 applies: G-AlSi11 is an eutectic alloy of excellent casting properties. It has mean strength at favorable expansion, it is weathering and corrosion resistant. It is suitable for complex, thin-walled, impact loaded casting parts. Application: equipment, machine, vehicle, ship and apparatus engineering cases, blade wheels, finned bodies, implement carrier, filter plates, facade plates.
