1) Remark: Aluminum casting alloy (sand casting, permanent mould casting, investment casting). Application: - cast products for structural railway applications - for castings with medium to large wall thickness, high strength and toughness (artificially hardened), corrosion resistant - aircraft construction - as investment casting also for thin-walled castings The alloy is food safe acc. to EN 601. Further properties according to EN 1706: Pressure tightness: good Machinability after heat treatment: good Corrosion resistance: good Weldability: good Sea water suitability: good (source: DNVGL-RU-SHIP Pt.2 Ch.2.
