Nitinol Flat Wire ASTM F2063

Product Specification

Descriptions

Nitinol Flat Wire ASTM F2063 is a precision-fabricated product made from nickel-titanium (NiTi) shape memory alloy. It is well known for its unique thermo-mechanical properties — shape memory effect (SME) and superelasticity (SE) — which distinguish it from conventional metallic materials.

The shape memory effect allows Nitinol to be deformed at one temperature and then recover its original shape when heated above its transformation temperature.
Superelasticity, on the other hand, occurs slightly above the transformation temperature, allowing the material to undergo large, reversible strains (up to 8%) without permanent deformation — 10 to 30 times higher than that of ordinary metals.

These exceptional mechanical and functional properties make Nitinol Flat Wire ASTM F2063 ideal for demanding applications in the medical, industrial, and consumer sectors.

Features and Advantages

1. Shape Memory Effect
   Automatically returns to its original shape upon heating due to reversible phase transformation between austenite and martensite phases.

2. High Superelasticity
   Exhibits significantly higher elastic strain recovery than standard metals, providing superior flexibility and fatigue resistance.

3. Excellent Fatigue Life
   Demonstrates a fatigue life exceeding 10⁷ cycles, ensuring long-term durability even under cyclic stress.

4. Good Corrosion Resistance
   Offers excellent resistance to corrosion in various environments, especially in physiological and saline conditions.

5. Superior Damping Properties
   Provides vibration absorption 10 times better than ordinary metals, enhancing performance in dynamic environments.

6. Stable Performance
   Maintains consistent elasticity and transformation behaviour under varying thermal and mechanical conditions.
