1) Remark: Aluminum alloy for castings (sand casting, permanent mould casting, pressure die casting). Further properties according to EN 1706: Pressure tightness: good (fair for pressure die castings) Machinability (as cast): good Corrosion resistance: poor Weldability: good Further information according to VAR Verband der Aluminiumrecycling-Industrie e.V., Düsseldorf: Very good castable heat-resistant universal alloy. Characterised by less tendency to collapse and internal shrinkage. Very good machinability. Application: tangled, thin-walled castings, e.g. complicated machine and engine parts for the automotive industry, electrical engineering, mining, crankcases and other housings, electric motor parts, bearing shields and blocks, cylinder heads, linings.
