Kurt Die Cast Alloys
At Kurt Die Cast we focus on 5 primary aluminum die casting alloys. Kurt has the capacity and
capability to add other alloys per our customers requirements. Aluminum die casting
alloys are lightweight with high dimensional stability. Aluminum has high thermal and
electrical conductivity, corrosion resistance, very good mechanical properties as well
as strength at high temperatures. Would you like to learn more about our aluminum die casting capabilities? Contact us or call 800-458-7855 for more information.

Aluminum Die Casting Alloy performance characteristics
380 - The most common aluminum die casting alloy with good fluidity & fair anodizing properties.
360 - Excellent pressure tightness and fluidity with a high silicon content.
369 - Very high silicon content. Excellent corrosion resistance, good fluidity and strength at elevated temperatures.
390 - Very high silicon content with elevated temperature strength but difficult machinability.
413 - Very high silicon content, good fluidity but with poor anodizing quality.
