What Is Nitinol Drive Wire?
Our drive wire is made from high-grade Nitinol, a nickel-titanium alloy renowned for its shape memory capability. This shape memory effect allows the wire to return to a preset form when heated, even after extensive deformation. Moreover, Nitinol’s superelasticity means it can undergo significant strain without permanent damage.
Nitinol’s unique properties enable high-precision, space-efficient actuation. Its proven biocompatibility supports safe integration in medical devices, while its mechanical resilience ensures reliable industrial performance.
Enhanced Surface Treatment for Long-Term Reliability
To promote extended service life, every drive wire undergoes fine polishing, which minimizes both surface friction and material fatigue during repeated motion. In addition, optional protective coatings—such as Parylene or thermal oxide layers—can be applied to boost resistance against corrosion and enhance electrical insulation. These surface enhancements make the wire consistently reliable in humid, chemically aggressive, or high-temperature conditions.
Wide Diameter Range for Diverse Applications
Our drive wire is available in a variety of diameters—from 0.1 mm to 2.0 mm—to suit a wide range of use cases:
0.1–0.5 mm: Perfect for fine-tuned movements in micro-actuators or minimally invasive tools.
1.0–2.0 mm: Designed for larger force output in robotics, aerospace systems, or load-bearing components.
We are able to provide dimension customization to precisely align with your all your engineering specifications.
