Superelastic NiTiCo Alloy Wire...
New product
Superelastic NiTiCo Alloy Wire retains the excellent shape memory effect and superelasticity of NiTi shape memory alloy, while the introduction of cobalt brings more stable phase transformation behavior, higher strength, and highly tunable transformation temperatures. Heeger Materials is a professional supplier and manufacturer of high-quality nitinol wire, offering customized solutions.

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.
