Product Introduction

Nickel Titanium (also known as Nitinol or NiTi) is a unique class of shape memory alloys (SMA). Its extraordinary properties come from a thermoelastic martensitic phase transformation, which enables both shape memory behavior and superelasticity.

Nitinol alloys typically consist of:

Nickel (Ni): 55% – 56%

Titanium (Ti): 44% – 45%

Even small composition variations can significantly change transformation temperature, mechanical behavior, and functional performance.

Material Standard
