High-Performance Actuators with Nitinol Shape Memory Wire
Advanced Material for Reliable Actuation
Our high-performance actuators are powered by Nitinol shape memory wire, a smart alloy made from 55% nickel and 45% titanium.Due to its exceptional superelastic and shape memory properties, the wire quickly contracts upon heating or electrical activation and subsequently reverts to its initial form.As a result, it delivers strong, repeatable force output across a wide temperature range. Moreover, Nitinol offers excellent corrosion resistance and long-term mechanical stability, making it ideal for harsh or demanding environments.
Smooth Surface Finish for Enhanced Durability
To improve both performance and lifespan, each Nitinol shape memory wire undergoes precision electrolytic polishing. This finishing step smooths the surface, eliminates micro-defects, and significantly enhances fatigue resistance. Furthermore, the mirror-like surface reduces internal friction during actuation and increases biocompatibility—especially important for medical applications. If additional protection is required, optional coatings such as Parylene or gold can be applied to meet specialized needs.
Flexible Diameter Options for Every Industry
We provide Nitinol wires in a wide diameter range, from 0.1 mm to 2.0 mm, to accommodate different force and space requirements:
0.1–0.5 mm: Best suited for micro-robotics, catheter control, and wearable tech.
0.5–1.5 mm: Common in aerospace, valves, and dynamic structural systems.
1.5–2.0 mm: Designed for heavy-duty use in automotive and energy harvesting applications.
In addition, we offer custom sizes to ensure a perfect fit for your design parameters.
Broad Applications Across Industries
Due to its lightweight, high-performance characteristics, Nitinol shape memory wire finds use in a wide range of fields:
Medical Devices: Stents, orthodontic wires, and surgical tools rely on Nitinol for flexibility and biocompatibility.
Robotics & Drones: These actuators drive artificial muscles, soft grippers, and adaptive structures.
Aerospace: Integrated into aircraft and satellite systems, these actuators regulate flaps, control valves, and deploy foldable structures with precision and minimal weight.
- Automotive: Applied in next-generation vehicles to operate adaptive air vents, optimize seat positioning, and manage thermal conditions in battery packs.
