• 2-way memory function: nitinol spring extends when heated to 50 degreeC (122 degreeF), and pulls/contracts when cooled to room temperature or below.
• 0.7mm wire; 9mm spring diameter; 16mm compressed length when cold; 30mm expanded length when hot
• Two way nitinol spring exerts force in both directions depending on its temperature. It pushes open when heated to 50C or more, and pulls shut when cooled below 30C. The pushing force is about double of the pulling force.
