Ni - Ti Alloy Temperature Guides
NiTi binary alloys designated by As (Austenite Start Temperature) in the fully annealed condition:
| Shape Memory Alloys |
|---|
| As = +95oC |
| As = +70oC |
| As = +60oC |
| As = +55oC |
| As = +45oC |
| Body Temperature Alloys |
|---|
| As = +5oC |
| As = +0oC |
| As = 0oC |
| As = -5oC |
| As = -15oC |
| As = -15oC |
| High Strength Superelastic Alloys |
|---|
| As = -25oC |
| As = -50oC |
NiTiCr: Superelastic alloys containing up to 1% chromium to improve strength.
NiTi- 6.6%Cu: Shape memory alloys containing copper to reduce the transformation temperature range and mechanical hysteresis.
NiTi-1.6% Fe: Superelastic NiTi with Fe to improve cold workability and stabilize R-phase transformation.
NiTi-3.4% Fe: Superelastic NiTi with Fe to reduce transformation temperature to the cryogenic temperature range; alloy also has higher cold workability.
