Quality Standards and Technical Specifications for 3mm Nitinol Rod

The quality standards and technical specifications for 3mm nitinol rod are primarily governed by China's industrial/national standards and international standards, covering core aspects such as chemical composition, dimensional tolerance, and mechanical properties. Below are the key details:

1. Chinese Standards

- YS/T 859 - 2013: Applies to linear superelastic nickel-titanium alloy rods. As a typical product, the 3mm rod has clear requirements for chemical composition, dimensions, and surface quality. The nickel content is 54.5% - 57.0% (mass fraction), with titanium as the balance. Impurities such as oxygen and carbon are strictly limited (O ≤ 0.050%, C ≤ 0.020%). The diameter tolerance is -0.03mm to 0mm, and the surface (oxidized, polished, or turned) must not have cracks or delamination.

- General Technical Specifications for Nickel-Titanium Alloy Rods: If used for medical implants, it must comply with GB/T 24627 - 2023. The average grain size in the transverse direction must not be coarser than grade 4, and the maximum size of pores and non-metallic inclusions is strictly restricted to ensure biocompatibility. Room temperature tensile tests can be performed as required, with specimens subjected to heating at ≥700℃ for ≥15 minutes followed by rapid cooling treatment.

2. International Standards

- ASTM F2063: This is the core standard for nickel-titanium alloy medical devices. Under this standard, the nickel content of 3mm nickel-titanium alloy rods is 54.5% - 57.0% (mass fraction). Its tensile strength is typically 700 - 1600MPa, matching its superelasticity and shape memory effect.

- ISO Series: ISO 13485 specifies the production quality management system to ensure product quality consistency. ISO 10993 requires that if used for implants, the 3mm rod must pass toxicity and cytotoxicity tests.

3. Other Key Specifications

- Supply Condition: Available in annealed or superelastic condition. The density is fixed at 6.45g/cm³, with a melting point range of 1240℃ to 1310℃.

- Surface Requirements: Polished, ground, or turned surfaces are provided. Only minor local scratches that do not affect performance are allowed. Visible metallurgical defects such as shrinkage cavities or inclusions must not be present in the transverse low-magnification microstructure.

Conclusion

The transformative impact of 3mm nitinol rod technology spans medical, aerospace, industrial, and consumer sectors, delivering unprecedented performance through unique shape memory and superelastic properties. As industries continue demanding materials combining flexibility, durability, and adaptive functionality, nickel-titanium alloy solutions will expand into emerging applications.
