Shape memory basics of Nickel-titanium ring

Nickel-titanium ring

Nickel-titanium rings, made from nickel-titanium alloy (Nitinol), are a functional element with shape memory and hyperelastic properties that play an important role in several industries.

I. Industry overview

Scale: The global nickel-titanium ring market continues to grow in size, mainly driven by demand from medical, aerospace and consumer electronics.

2. product classification

Classification by function:
Shape memory nickel-titanium ring: can restore a preset shape at a specific temperature, used in medical devices, aerospace and other fields.
Superelastic nickel-titanium ring: can withstand large deformation without breaking, used in electronic, mechanical and other fields.
Classification by shape: round, square, rectangle, shaped, etc.
Classified by surface treatment: polishing, sandblasting, oxidation, etc.

3. Application fields
