Nitinol Wire Spring for Medical Devices
Shape-Setting Performance You Can Trust
Our nitinol wire spring is a critical component for modern medical devices requiring precise shape memory and superelasticity. Made from premium nickel-titanium alloy, this smart material returns to its pre-set shape when activated by heat—making it ideal for life-saving applications inside the human body. Whether in guidewires, implants, or surgical tools, our springs provide the consistent performance medical professionals rely on.
Superelastic Nitinol Wire – Medical Grade Quality
Crafted from certified medical-grade nickel-titanium, each nitinol wire spring offers:
Superelastic behavior: Recovers its initial geometry immediately after substantial deformation.
Shape memory function: Recovers its programmed shape when heated.
Biocompatibility: Fully compliant with ISO 13485 for safe in-body use.
These properties make our nitinol wire springs ideal for dynamic and complex movements within minimally invasive instruments.
Polished Surface – Safe & Long-Lasting
Our nitinol wire spring features a meticulously polished surface for:
Smooth operation: Minimizes friction in movement-critical devices.
Tissue safety: Designed to lower the likelihood of biological reactions such as irritation.
Corrosion resistance: Withstands bodily fluids and sterilization processes.
A flawless surface extends device longevity while enhancing patient comfort.
Flexible Diameter Options – From Micro to Macro
Available in sizes from 0.05 mm (0.002″) up to 1.5 mm (0.060″), our nitinol wire springs support a broad range of device designs. We also accommodate custom diameters—ask us about tailored specifications for your prototype or product line.
