Shape Memory Effect: Driven by the phase transformation between austenite and martensite inside the alloy, after being deformed by external force within a specific temperature range (such as human body temperature), it can restore its original shape through heating or cooling, providing technical support for self-expanding devices.

Superelasticity: At room temperature or human body temperature, it can withstand 8%-10% elastic deformation and instantly return to its original shape after the external force is removed, with no permanent deformation. Corresponding to the performance data of nitinol tubes/wires: tensile strength ≥1000Mpa, 6% residual deformation ≤0.3%.

Corrosion Resistance: A dense oxide film is formed on the surface, which can resist erosion by human body fluids (blood, tissue fluid) and has no risk of corrosion failure during long-term implantation.

Biocompatibility: No adverse reactions with human tissues and blood, non-toxic and non-sensitizing. Certified by SGS, passing comprehensive biosafety tests such as acute toxicity, skin sensitization, and intradermal reaction tests.
