Balancing Ductility and Strength: Trade-offs in AZ91D Applications

AZ91D has around 3% elongation, which is actually quite low compared to AM60B's impressive 15%. But what AZ91D lacks in flexibility it makes up for in stiffness, clocking in at 45 GPa versus 38 GPa for AM60B. This makes AZ91D pretty good for things that need to hold weight or support structures. When designing with this material, engineers often add ribs inside laptop frames to make up for its tendency to snap under stress. Some recent changes at the microscopic level have helped too. Now AZ91D can stretch to about 5% without losing its strength characteristics, so the difference between how strong it is versus how much it can bend before breaking isn't quite as big as it used to be.
