Typical properties of NiTi alloys
Nickel-titanium shape memory alloys - Material data sheets

Physical properties depend on the structure (table 5).

The main physical properties of use are as follows:

• density: 6,450 kg/m³ ;

• melting temperature: 1,300°C.

• Degradation of memory properties and fatigue

  For general use, please refer to table 6, which gives the maximum deformation values recoverable by memory effect and the maximum force usable when recovering the high-temperature form, as a function of the number of use cycles (according to [1]).

  Higher values can be achieved with NiTi-Cu alloys. In addition to the effect...
