EN AC-43300 (DIN EN 1706 : 2020-06)	EN AC-43300	DIN EN 1706 : 2020-06	DIN EN 1706 : 2020-06 replaced by DIN EN 1706 : 2021-10	Replaced	Germany	EN AC-Al Si9Mg	EN AC-Al Si9Mg	Aluminum casting alloy (sand casting, permanent mould casting). Application: - cast products for structural railway applications - for complex, thin-walled castings with high strength and good toughness (artificially aged) and very good corrosion resistance - aircraft construction The alloy is food safe acc. to EN 601. Further properties according to EN 1706: Pressure tightness: good Machinability (as cast): good/fair Machinability after heat treatment: good Corrosion resistance: good Weldability: excellent
