Main uses: fishing line,super elastic memory alloy mobile phone antennas,optical glasses frames, Bluetooth headsets, medical.
nitinol wire alloy code:
Regular binary NiTi alloy code, main composition, and typical active Af temperature (per ASTM F2063-05 or GB 24627-2009)
*The real active Af temperature may varies with actual composition, thermo-mechanical history of the products.

available in either as straightened super-elastic (SE) wire or the cold worked (CW) condition wire ready for heat treatment.
Heat Treatment Status:
Medical grade Nitinol wire may be purchased in the super-elastic condition (SE) or the cold worked (CW), and after the correct
supper-elastica heater treatment will accommodate strain up to 8% without permanent kinking at body temprature.
