0.04” x 73” Nitinol Wire – Reliable Shape Memory Solution

Precision Nitinol Wire for Advanced Applications

The 0.04” x 73” Nitinol wire is a high-performance smart material engineered for applications requiring flexibility, durability, and reliable shape recovery. Manufactured from genuine nickel-titanium alloy, this precision wire delivers both shape memory effect and superelastic behavior, making it suitable for demanding medical and industrial environments.

Our 0.04” x 73” Nitinol wire meets strict quality standards and provides consistent performance from batch to batch.

Material Properties of 0.04” x 73” Nitinol Wire

Nitinol is a unique alloy composed of nearly equal parts nickel and titanium. This precise composition enables its extraordinary functional properties.

• Alloy Composition: Nickel (~55.8%), Titanium (~44.2%)

• Primary Phase: Austenite (superelastic) or Martensite (shape memory), customizable

• Key Properties: Shape memory effect, superelasticity, high fatigue resistance

• Biocompatibility: Suitable for medical and long-term applications

The wire features a smooth, polished surface that minimizes friction and enhances corrosion resistance, ensuring long-term reliability even in harsh operating conditions.

Shape Memory and Superelastic Performance

The defining feature of the 0.04” x 73” Nitinol wire is its dual functional behavior. Through controlled thermal processing, the wire is shape-set to “remember” a specific form. When deformed at lower temperatures, heating the wire activates the shape memory effect, causing it to return precisely to its original configuration.

In addition, the wire exhibits excellent superelasticity. It can endure large strains and repeated bending cycles. Once the applied stress is removed, the wire immediately recovers its original shape without the need for heat. This makes it ideal for dynamic applications involving continuous movement or flexing.
