EN AC-44300 (DIN EN 1706 : 1998-06) EN AC-44300 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany GD-AlSi12 EN AC-Al Si12(Fe)(a) 2.1 1)
1) Remark: Material EN AC-AlSi12(Fe) is produced as diecasting. It shows the following casting characteristics and properties: plasticity: excellent heat crack resistance: excellent pressure tightness: acceptable workability (after heat-treatment): acceptable corrosion resistance: acceptable decorative anodic oxidation: not advisable weldability: insufficient polishability: insufficient strength at room temperature: good strength at increased temp. (up to 200°C): acceptable 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-AlSi12, mat. No. 3.2582, acc. to DIN 1725-2 : 1986-02 applies: The material an unhardenable eutectic alloy of excellent form matching capability, high heat-crack resistance, favorable casting properties and high chemical resistance. It is suitable for higher loaded corrosion and vibration resistant casting parts. Application: machine parts, shock and vibration loaded parts, cylinder heads and blocks, engine-, crank- and pump cases, blade wheels, finned bodies, thinn-walled cases, complex assembly blocks and plates.
