1) Remark: Non-precipitation hardenable aluminum casting alloy (sand casting, permanent mould casting) for castings with decorative surface. The alloy is food safe acc. to EN 601. Further properties according to EN 1706: Pressure tightness: poor Machinability (as cast): excellent Corrosion resistance: excellent (especially against sea water and alkalescent media) Weldability: fair Further information according to VAR Verband der Aluminiumrecycling-Industrie e.V., Düsseldorf: Excellent polishability and anodic oxidisability. However, the casting properties are less favourable due to the lower Si content. Excellent corrosion resistance, especially to seawater and weak alkaline media. Application: for castings with decorative surfaces, interior and exterior fittings for vehicles and construction, decorative furnishings, household appliances, appliances for the food industry, panelling
