Nitinol 2-Way Memory Coil Spring W0.75 x D6.5 x C16; Af 55

  • $ 18.00


Nitinol pre-trained 2-way memory helical/coil spring contracts and exerts force when heated to 55C. Once cooled to room temperature, the spring extends by itself exerting force in the opposite direction. Cold length: 50mm (without hooks). This spring pulls with a force of up to 300 grams, but in order to prevent damage to the spring's structure, the recommended maximum load should not exceed 170 grams.


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