EN AC-51400 (DIN EN 1706 : 1998-06) EN AC-Al Mg5(Si) EN AC-51400 DIN EN 1706 : 1998-06 DIN EN 1706 : 1998-06 replaced by DIN EN 1706 : 2013-12 Replaced Germany G-AlMg5Si EN AC-Al Mg5(Si) 2.1 1)
1) Remark: Material EN AC-AlMg5(Si) is produced as sand and chilled cast. It shows the following casting characteristics and properties: plasticity: acceptable heat crack resistance: insufficient pressure tightness: insufficient workability (after heat-treatment): excellent corrosion resistance: excellent decorative anodic oxidation: good weldability: acceptable polishability: excellent strength at room temperature: insufficient strength at increased temp. (up to 200°C): good 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]). To the comparable DIN-mark G-AlMg5Si, mat. No. 3.3261, acc. to DIN 1725-2 : 1986-02 applies: The alloy is well castable and has an excellent weathering and corrosion resistance. Suitable for complex cast parts of higher requirements to impact bending ductility and surface quality, excellent brightenable. Application: shipbuilding, vehicle and aircraft construction, chemical and food industry, decorative casting parts, fittings of all kind, facade plates and facing.
