nitinol wire (5)

nitinol wire

The main brands of medical nitinol wire materials are super elastic binary nickel titanium NiTi-01M and ternary copper nickel titanium CuNiTi. The phase transition temperature Af ranges from - 25 ℃ to 35 ℃. It is used for dental orthopedic wire, root canal file, preparation instruments, maxillofacial instruments, etc. in oral treatment, intramedullary needle, perforation nail, suture thread, etc. in surgical treatment, vascular stent, guide wire, basket, repair clip, occluder, stapler, etc. in minimally invasive treatment center.

Product characteristics：

1，Shape memory

nitinol shape memory alloy will automatically restore its shape after certain heat treatment, which is the shape memory feature of NiTi shape memory alloy.

2，Hyperelasticity

,NiTi shape memory alloy will deform when subjected to external force, and will return to the original state after removing the external force, which is the super elastic feature of NiTi shape memory alloy.

3，Damping property

NiTi shape memory alloy (SMA) has a very good damping property because of the self adjustment of phase transformation and the interface and movement generated in phase transformation.

4，Resistivity

During the deformation of martensitic NiTi shape memory alloy, the relationship between resistance and strain is linear. When the transformation occurs, the slope of the curve will decrease accordingly, however, the linear relationship will also be maintained before and after the martensite phase.
