| EN AC-47000 (DIN EN 1706 : 2021-10) | EN AC-47000 | DIN EN 1706 : 2021-10 | Supersedes DIN EN 1706 : 2020-06 | Valid | Germany | EN AC-Al Si12(Cu) | Non-precipitation hardenable aluminum casting alloy (sand casting, permanent mould casting). Further properties according to EN 1706: Pressure tightness: excellent Machinability (as cast): fair Corrosion resistance: fair 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 |
