367.0 and 368.0^[1]: Low-Iron Premium Die-Casting Alloys

The aluminum alloys 367.0 and 368.0 are high-performance, low-iron, die-casting alloys that rely on strontium for die soldering resistance. In these alloys, the lower iron content minimizes the formation of needle-like, Al-Fe-Si phases that can deteriorate strength, elongation and fatigue behavior. This datasheet provides information on key alloy metallurgy, processing effects on tensile properties, and fabrication characteristics of these 3xxx series alloys.
