Other Properties

Castability Fair for sand and gravity die casting, limited for high pressure die casting Shrinkage Sand casting: 1.0–1.4%; gravity die casting: 0.9–1.2% Machinability Excellent Weldability Fair Corrosion resistance Excellent, even sea water resistant Surface treatment Anodizing and polishing for decorative purposes

Melt Treatment

Mg-loss and hydrogen pick-up during melting can be reduced by small additions of Be Thorough degassing is necessary Grain refinement with Ti-B is recommended Casting temperature: 690 to 740°C

Heat Treatment

With the low Si content, the alloy is not heat treated.
