Nitinol Shape Memory Spring for Medical & Industrial Use
The nitinol shape memory spring is engineered for high-performance environments requiring accuracy, durability, and adaptive motion. Constructed from a Nickel-Titanium alloy, this spring features unique shape memory and superelastic properties.When subjected to heat or mechanical stress, it returns to its pre-set form.
High-Quality Nitinol Alloy
Our nitinol shape memory springs are produced using high-purity Nickel-Titanium, known for its excellent fatigue resistance, biocompatibility, and corrosion resistance. These properties ensure the spring performs reliably in long-term use, especially in surgical and high-tech industrial devices.
Versatile Surface Finishes
To improve performance, every shape memory spring is subjected to surface treatment processes:
Mechanical polishing ensures a clean, consistent surface
Electrochemical polishing lowers surface friction and enhances corrosion resistance.
Sandblasting creates a matte finish for improved tactile grip
These finishes help the nitinol spring operate efficiently in sensitive or sterile environments.
Wide Diameter Range for Custom Needs
We manufacture nitinol shape memory springs in sizes ranging from 0.1 mm to 5.0 mm:
0.1–1.0 mm: Used in minimally invasive tools and electronics
1.1–3.0 mm: Widely applied in catheter systems, dental braces, and compact robotics.
3.1–5.0 mm: Perfect for industrial and mechanical assemblies
Custom diameters and geometries are available for tailored solutions.
