Product description
Nickel tubes, primarily composed of nickel and titanium, are special tubes with shape memory effect (recovering more than 95% deformation within a specified range) and superelasticity (recovering strain ≥8%).
They have high dimensional accuracy, with strictly controlled tolerances for outer diameter, wall thickness, etc. Straightness ≤0.5mm/m, roundness ≤0.03mm, exhibiting excellent performance. In terms of properties, tensile strength ≥900MPa, elongation ≥20%, good corrosion resistance, and excellent biocompatibility, meeting standards such as ISO 10993 and GB/T 16886.
