Characteristics of Nitinol Wire

1. Shape Memory Effect

Nitinol wire can return to its pre-set shape when heated above its Austenite finish temperature (Af), offering >8% strain recovery for actuators and deployable structures.

2. Superelasticity

Exhibits extraordinary recoverable strains and kink resistance, ideal for flexible medical devices and dynamic applications.

3. Biocompatibility

Zero tissue rejection and no metallic ion release, making it perfect for medical implants like stents and orthodontic wires.

4. Corrosion Resistance

Resists corrosion in harsh environments, including seawater, acids, and alkalis, ensuring >10x lifespan compared to stainless steel.

5. High Strength-to-Weight Ratio

Matches the strength of alloy steel while being 43% lighter, enabling lightweight designs in aerospace and wearables.

6. Wide Temperature Range

Maintains performance from cryogenic (-250°C) to elevated temperatures (600°C), suitable for extreme environments.

7. Precision Processing

Supports ultra-fine wire drawing (down to Ø0.01mm), braiding, and additive manufacturing for complex applications.
