EN AC-42100 (DIN EN 1706 : 2021-10) EN AC-Al Si7Mg0,3 EN AC-42100 DIN EN 1706 : 2021-10 Supersedes DIN EN 1706 : 2020-06 Valid Germany EN AC-Al Si7Mg0,3 2.1 1)
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 - for the production of pressure equipment in accordance with EN 12392 - recommended for marine applications, including shipbuilding and offshore applications (source: EN 13195) 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. Edition July 2019)
