EN AC-46200 (DIN EN 1706 : 1998-06) EN AC-46200 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany GD-AlSi9Cu3 EN AC-Al Si8Cu3 1)
1) Remark: Material EN AC-AlSi8Cu3 is produced as sand, chilled and diecast. It shows the following casting characteristics and properties: plasticity: good heat crack resistance: good pressure tightness: good acceptable (diecast) workability (after heat-treatment): good corrosion resistance: insufficient decorative anodic oxidation: not advisable weldability: good polishability: acceptable strength at room temperature: good strength at increased temp. (up to 200°C): excellent 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]). Diecasting weldability depends on the embedded gas amount and is mostly insufficient. For certain casting methods are achievable good to acceptable values. To the comparable DIN-mark GD-AlSi9Cu3, mat. No. 3.2163, acc. to DIN 1725-2 : 1986-02 applies: The material an all-round alloy of excellent casting properties and high machinability. It has a lower tendency to cavities and it is mostly unhardened. It is suitable for complex, thin-walled, pressure tight, vibration resistant and impact loaded casting parts. Application: Complex machine and engine parts for vehicle industry, e-technics, mining etc., crank and other cases, electro engine parts, end shields and brackets, cylinder heads, paneling etc.
