Nitinol 2-Way Memory Coil Spring W1 x D33 x C5 x H55 Af 60

  • $ 20.00

Nitinol pre-trained 2-way memory helical/coil spring expands and exerts force when heated to 45-60C. Once cooled to room temperature, the spring contracts on its own with substantial pulling force. The higher activation (60C) spring contracts completely at room temperature very quickly, the lower activation (45C) spring contracts at room temperature slower, but both return to fully collapsed at up to 25C.


This variant of the NiTi spring expands when heated and contracts on its own when cooled, providing force in both directions (2-way).

  • Spring wire gauge: 1.0 mm
  • Diameter: 33 mm
  • Fully contracted (cold) length: 5 mm
  • Fully extended (hot) length: 55 mm
  • Weight: 4.54 grams
