Product Introduction

Nickel Titanium (commonly known as Nitinol or NiTi) is a unique shape memory alloy (SMA) that exhibits two remarkable properties:

Shape Memory Effect
Superelasticity

These properties result from a thermoelastic martensitic phase transformation, which allows the material to recover its original, predetermined shape after deformation when exposed to the appropriate temperature.

Because of its excellent flexibility, fatigue resistance, corrosion resistance, and biocompatibility, Nitinol has become one of the most important advanced materials used in medical devices and precision engineering applications.

Chemical Composition

Typical composition of Nitinol alloy:

Element	Content
Nickel (Ni)	55% – 56%
Titanium (Ti)	44% – 45%

Even very small variations in nickel content (±0.1%) can significantly influence:

Phase transformation temperature

Superelastic behavior

Mechanical performance

Therefore, precise composition control is critical in Nitinol manufacturing.

Key Technical Terms

Af – Austenite Finish Temperature

The temperature at which the transformation from martensite to austenite is completed.

Ms – Martensite Start Temperature

The temperature at which the transformation from austenite to martensite begins.

Hysteresis

The temperature difference between the forward and reverse phase transformations.

Control of these parameters allows engineers to precisely design shape memory or superelastic behavior for specific applications.

Applications

Nitinol is widely used in medical devices and high-precision engineering components, especially where flexibility, durability, and biocompatibility are required.
