Products Description
Basic knowledge of brown Nitinol SMA Wire
Brown Nitinol SMA Wire is a surface treatment form of nickel-titanium alloy wire, mainly composed of nickel (Ni) and titanium (Ti), with the ratio of the two being close to 1:1. Its "brown" color usually results from surface oxidation treatment or special coating processes, which enables the material to maintain the inherent properties of nickel-titanium alloys while having specific appearance and performance optimizations.
Production process of Nitinol SMA Wire
Annealing treatment: After surface treatment, low-temperature annealing is carried out to eliminate internal stress and stabilize the structure of the oxide layer, preventing fading or peeling during use.
Polishing and cleaning: Improve surface roughness through mechanical polishing or chemical etching, and use ultrasonic cleaning to remove impurities to ensure uniform coating adhesion.
The core of these processes lies in achieving a synergistic optimization of the brown appearance and performance (such as corrosion resistance and biocompatibility) by controlling the composition, thickness and microstructure of the surface layer. The specific process selection needs to adjust parameters according to the application scenario (medical, industrial, etc.).
| Mechanical properties | |
| Super elasticity | It can automatically return to its original shape within a certain deformation range. |
| Memory effect | After heating, it can "remember" and return to its original shape, which is divided into one-way and two-way memory effects. |
| Tensile strength | 800-1500MPa |
| Physical properties | |
| Phase transition temperature (Afc) | -50℃ ~ +120℃ |
| Density | 6.45g/cm³ |
| Corrosion resistance | The surface oxide layer enhances the resistance to body fluids, acids and alkalis corrosion. |
| Surface characteristics | |
| The thickness of the brown oxide layer is uniform, the roughness is controllable, and it can improve the compatibility with other materials. | |
