EN 1706 AC-51000 F Aluminum Alloy – Performance & Applications
Material EN AC-AlMg3(b) is produced as sand and die 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: excellent weldability: acceptable polishability: acceptable 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]).
