Product Overview
Superelastic Nitinol Wire for Biomedical Stents and Guidewires

Superelastic Nitinol wire represents a significant advancement in nickel-titanium alloy technology, combining exceptional flexibility with remarkable durability. This specialized wire features unique shape memory properties that allow it to stretch and return to its original form without permanent deformation, making it particularly valuable for biomedical applications such as stents and guidewires.

With a balanced composition of approximately 50% nickel and 50% titanium, our Nitinol wire offers superior corrosion resistance and biocompatibility, meeting the stringent requirements of medical device applications. Our production process ensures strict adherence to ASTM F2063 standards, guaranteeing reliable performance in critical medical and industrial environments.

Material Composition and Grades

Our superelastic Nitinol wire is manufactured with precision-controlled materials:

  • Nickel content: 54.5-57.0%
  • Titanium: Balance
  • Trace elements (carbon <0.05%, oxygen) carefully controlled for optimal biocompatibility
  • Advanced melting, drawing, and heat treatment processes to achieve consistent superelastic properties
  • Transition temperature range: -20°C to 40°C for biomedical applications
