| EN AC-46400 (DIN EN 1706 : 1998-06) | EN AC-46400 | DIN EN 1706 : 1998-06 | DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 | Replaced | Germany | EN AC-Al Si9Cu1Mg | Material EN AC-AlSi9Cu1Mg is produced as sand and chilled cast. It shows the following casting characteristics and properties: plasticity: good heat crack resistance: good pressure tightness: good workability (after heat-treatment): good workability (casting condition): good corrosion resistance: insufficient decorative anodic oxidation: not advisable weldability: good polishability: insufficient strength at room temperature: excellent strength at increased temp. (up to 200°C): good ductility (impact strength): acceptable 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]). |
