EN AC-44200 (DIN EN 1706 : 2021-10)	EN AC-44200	DIN EN 1706 : 2021-10	Supersedes DIN EN 1706 : 2020-06	Valid	Germany	EN AC-Al Si12(a)	Not artificially age-hardenable aluminum casting alloy (sand casting, permanent mould casting). Application: - cast products for structural railway applications - 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: excellent Machinability (as cast): fair Corrosion resistance: good Weldability: excellent Further information according to VAR Verband der Aluminiumrecycling-Industrie e.V., Düsseldorf: Eutectic alloy with excellent mould filling capacity, high hot cracking resistance and excellent casting properties with high chemical resistance. Application: for complex, thin-walled, pressure-tight and vibration-resistant castings with very good corrosion resistance, e.g. machine parts, parts subject to impact and vibration stress, cylinder heads and blocks, engine, crank and pump housings, impellers, ribbed bodies, thin-walled housings, difficult mounting blocks and plates
