In a way, yeah it is a better spring steel. Many shape memory alloys, besides their famous shape-changing-under-heating behavior, can also have superelastic properties, meaning they can reversible handle much larger strains than typical alloys (by a reversible phase change in the material). This means they can work as a better spring alloy. https://en.wikipedia.org/wiki/Pseudoelasticity

Nitinol typically has tight compositional tolerances and is used for things like stents and catheters. It's nothing new in the medical field. But it'd be pretty damn impressive to manufacture something so finely structured out of nitinol at scale.

Oh, it’s not that uncommon. You can buy Nitinol wire pretty cheaply, although not the medical-approved stuff.
