More info

Superelastic NiTiCo Alloy Wire builds upon the foundation of classic NiTi shape memory alloy, delivering a significant leap in performance through the precise addition of cobalt. The introduction of cobalt brings more stable phase transformation behavior, higher strength, and highly tunable transformation temperatures. This translates to more reliable actuation force, extended fatigue life, and superior capability to perform in higher temperature and more demanding environments. Available in a range of sizes and grades, HM's Nitinol Wire meets the highest standards of quality and reliability for demanding applications.

Superelastic NiTiCo Alloy Wire Mechanical Properties at different temperatures

Superelastic NiTiCo Alloy Wire Features

  • Higher rigidity
  • Higher upper and lower yield platforms
  • Lower phase transformation temperature
  • Wider superelastic temperature range

Superelastic NiTiCo Alloy Wire Applications

  • High-Strength Guidewire: The ternary nickel-titanium-cobalt alloy guidewire, compared to the binary nickel-titanium alloy guidewire, benefits from the addition of cobalt, which enhances the wire's upper and lower yield platforms as well as its elastic modulus. This makes it an ideal core wire for guidewires, providing superior passability within the lumen.
  • Building Vibration Damping: Nickel-titanium-cobalt alloys maintain excellent superelasticity at low temperatures, making them a promising solution for building vibration damping or outdoor superelastic applications.
  • Downhole tool components for the petroleum industry
  • Anti-fatigue transmission components in the automotive field
  • Constant-force elements in precision instruments
  • High-performance springs with precise trigger temperatures
  • High-precision aerospace actuators and fasteners

Superelastic NiTiCo Alloy Wire Packaging

Superelastic NiTiCo Alloy Wire will be packaged in custom foam inserts within sturdy wooden crates. This multi-layer protection ensures the ingots are shielded from impacts, vibrations, and environmental changes, arriving safely in optimal conditions.
