Non-heat treatment-type, high toughness, die cast alloys

Adding Si to the conventional Al-Mg alloy improves castability and reduces casting cracks.

In addition, eliminating the need for heat treatment reduces costs.

DX50
Al-Mg-Si alloy
DX55
Al-Mg-Si alloy
Tuning of the Mg and Si content of DX50 results in this improved elongation.
