Description
Superelastic Flat Metal Wire (Nitinol) 0.55mm x 0.78mm
Superelastic Nitinol Grades:
We offer this flat wire in standard Superelastic Nitinol grades. These Nitinol grades are precision‑engineered to balance strength and flexibility, ensuring consistent, dependable performance for critical applications.The material is optimized for reliable performance at physiological temperatures. Common grades include SE508 and equivalents.
Unmatched Properties
-
Superelasticity (Pseudoelasticity): Bends sharply and snaps back to its original shape reliably, millions of times.
-
Shape Memory: Returns to a preset form when heated, ideal for actuators and thermal triggers.
-
Biocompatibility: Medical-grade material, making it safe for long-term implantation.
-
Corrosion Resistance: The clean oxide surface protects against harsh environments, including body fluids and chemicals.
-
Fatigue Resistance: Exceptional durability under repetitive stress compared to ordinary alloys.
-
Consistent Force: Provides stable forces across a range of motion — vital for medical devices and precision engineering.
-
MRI Compatibility: Enables medical applications in MRI environments, unlike many traditional metals.
Why Choose the Clean Oxidized State?
-
Protective Finish: Prevents surface damage during handling and processing.
-
Consistent Quality: Enables precision laser cutting, welding, and coating.
-
Cost-Effective: Ready-to-use surface right from the factory.
Key Applications for Flat Metal Wire
