EN AC-44100 (DIN EN 1706 : 1998-06) EN AC-Al Si12(b) EN AC-44100 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany EN AC-Al Si12(b) 2.1 1)
1) Remark: Material EN AC-Al Si12(b) is produced as sand, chilled and precision casting. 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 to acceptable 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): good 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]).
