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
Shape Memory Effect
Automatically returns to its original shape upon heating due to
reversible phase transformation between austenite and martensite
phases.
High Superelasticity
Exhibits significantly higher elastic strain recovery than standard
metals, providing superior flexibility and fatigue resistance.
Excellent Fatigue Life
Demonstrates a fatigue life exceeding 10⁷ cycles, ensuring
long-term durability even under cyclic stress.
Good Corrosion Resistance
Offers excellent resistance to corrosion in various environments,
especially in physiological and saline conditions.
Superior Damping Properties
Provides vibration absorption 10 times better than ordinary metals,
enhancing performance in dynamic environments.
Stable Performance
Maintains consistent elasticity and transformation behaviour under
varying thermal and mechanical conditions.
