EN AC-21000 (DIN EN 1706 : 2021-10)	EN AC-21000	DIN EN 1706 : 2021-10	Supersedes DIN EN 1706 : 2020-06	Valid	Germany	EN AC-Al Cu4MgTi	Aluminum casting alloy (sand casting, permanent mould casting, investment casting). Application: - cast products for structural railway applications - for simple castings with highest strength (artificially aged) or highest toughness (naturally aged) - aircraft construction - as investment casting also for complex castings - for the production of pressure equipment in accordance with EN 12392 Further properties according to EN 1706: Pressure tightness: poor Machinability after heat treatment: excellent Corrosion resistance: poor Weldability: poor
