Shape Memory Alloy Wire: Superelastic Power, Smart Functionality

Unlock the transformative capabilities of shape memory alloy wire. Our premium-grade Nitinol wire harnesses the power of both shape memory and superelasticity, delivering unmatched performance across a wide range of industries. Engineered for precision, flexibility, and durability, it’s a material that adapts, responds, and delivers.

Engineered Material Excellence

Each spool of wire is crafted from high-purity Nickel and Titanium, meeting strict standards like ASTM F2063. This ensures consistent performance, precise transformation temperatures, and reliable mechanical properties — batch after batch.

Superelastic Nitinol Wire – Unmatched Flexibility

Our superelastic Nitinol grades flex like rubber and rebound like steel. They endure extreme bending and twisting without permanent deformation, returning instantly to their original shape. This property activates at body temperature, making it the go-to choice for advanced medical and consumer applications.

Comprehensive Diameter Range

Whether your project demands ultra-fine wire or robust gauges, we offer a full spectrum of diameters:
From 0.02 mm (0.00075″) up to 5.0 mm (0.197″) – with custom sizing available to match your exact specifications.

Applications of Shape Memory Alloy Wire

Shape memory alloy wire offers practical, innovative solutions across demanding industries:

Medical Devices

• Stents & Guidewires: Our Nitinol wire enables self-expanding stents and highly navigable guidewires. These devices use body heat to deploy reliably and maneuver smoothly through complex anatomy, improving patient outcomes.

• Orthodontics: Dentists rely on Nitinol archwires for effective teeth alignment. The wire applies consistent, gentle force throughout treatment, offering greater patient comfort and efficient results.

• Catheters & Retrieval Tools: We supply Nitinol for critical catheter components and precise retrieval tools. The material’s superelasticity ensures exceptional flexibility and control during minimally invasive procedures, enhancing precision and minimizing tissue trauma.

Robotics & Actuation

• Actuators & Valves: Wire contracts when heated, enabling powerful linear motion in tight spaces.

• Smart Mechanisms: Ideal for robotic fingers, latches, and remote release systems.

Aerospace & Defense

• Deployable Structures: Nitinol wire powers mechanisms in satellites and aircraft components.

• Vibration Dampening: Provides resilience in dynamic, high-stress environments.

Consumer Products

• Eyeglass Frames: Flexible, virtually unbreakable frames that always return to shape.

• Smart Textiles & Appliances: Temperature-sensitive applications for comfort and efficiency.

Industrial Engineering

• Connectors & Seals: Superelastic wire maintains structural integrity under repetitive stress.

• Safety Devices: Temperature-triggered release systems that enhance industrial safety.
