1) Remark: Not artificially age-hardenable aluminum casting alloy (sand casting, permanent mould casting, investment casting). 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/fair Weldability: excellent Sea water suitability: good/moderate (source: DNVGL-RU-SHIP Pt.2 Ch.2. Edition July 2019) 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
