Nitinol 1-Way Memory Coil Spring W0.75 x D6.5 x C16; Af 45

  • $ 9.00


Nitinol pre-trained 1-way memory helical/coil spring contracts and exerts force when heated to 45C. Once cooled to room temperature, the spring requires almost no resistance to collapse it. Recommended maximum expansion when cold: 50mm (without hooks). This spring pulls with a force of up to 400 grams, but in order to prevent damage to the spring's structure, the recommended maximum load should not exceed 230 grams.


This variant of the NiTi spring expands when heated and can be mechanically expanded when cooled with little resistance.

  • Diameter: 6.5 mm
  • Fully contracted (hot) length: 16 mm
  • Fully extended (cold) length: 50 mm
