Superelasticity Unleashed
How Nitinol handles extreme stress without permanent damage.
- Beyond Memory
The Second Magic Trick
While shape memory requires heat to trigger a change, Nitinol has a second, colder superpower: superelasticity.
- Mechanical Trigger
Stress-Induced Shift
In this mode, the alloy doesn't need a flame. Pure physical pressure is enough to force the atoms into a new arrangement.
- Comparison
Rubber vs. Metal
Standard metals deform permanently when stretched too far. Superelastic Nitinol can endure ten times more strain than steel.
