EN AC-44300 (DIN EN 1706 : 2021-10) EN AC-Al Si12(Fe)(a) EN AC-44300 DIN EN 1706 : 2021-10 Supersedes DIN EN 1706 : 2020-06 Valid Germany EN AC-Al Si12(Fe)(a) 2.1 1)
1) Remark: Non-precipitation hardenable aluminum casting alloy (pressure die casting). The alloy is food safe acc. to EN 601. Further properties according to EN 1706: Pressure tightness: fair Machinability (as cast): fair Corrosion resistance: good/fair Weldability: poor 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, higher-stress, corrosion-resistant and vibration-resistant castings with very good corrosion resistance, e.g. machine parts, parts subject to impact and vibration, cylinder heads and blocks, engine, crank and pump housings, impellers, ribbed bodies, thin-walled housings, difficult mounting blocks and plates
