Shape Memory Nickel Titanium Alloy, often referred to as Nitinol, is a unique metal alloy known for its ability to return to a predetermined shape when heated above a certain temperature. This property is due to its distinct phase transformation characteristics, which allow it to exhibit both superelasticity and shape memory effects. The alloy is primarily composed of nickel and titanium, typically in a roughly 50:50 ratio, and is processed through methods such as cold working and heat treatment to achieve desired properties.
| Composition | Approximately 50% Nickel and 50% Titanium |
| Phase Transformation Temperature | Typically between 30°C to 100°C |
| Density | Approximately 6.45 g/cm³ |
| Young's Modulus | Approximately 70-80 GPa |
| Fatigue Life | Can exceed 10 million cycles under proper conditions |
When choosing Shape Memory Nickel Titanium Alloy, buyers should consider the specific phase transformation temperature required for their application, as well as the desired mechanical properties such as elasticity and fatigue resistance. It is also important to specify the alloy's composition and any necessary certifications for medical or aerospace applications. Quantities may vary based on project needs, so it's advisable to provide an estimate to suppliers when requesting a quote.
