❓ Frequently Asked Questions (FAQ)
Q: What is the difference between superelastic and shape memory Nitinol?
A: Superelastic Nitinol recovers shape at room temperature, while shape memory Nitinol requires heat activation.
Q: Can Nitinol wire be soldered or welded?
A: Yes, but specialized techniques (laser welding, resistance welding) are recommended.
Q: Is Nitinol MRI-compatible?
A: Yes, it is non-ferromagnetic and safe for MRI environments.
