Nitinol SMA Shape Memory Spring 45-60C (113-140F) Activation Temperature

Master selector for our nitinol springs that are in-stock ready for immediate shipment. Select between 1-way or 2-way function. 1-Way 'Contract when hot' springs must be pulled open when cold manually. 2-Way 'Contact when hot' springs expand when cooled by themselves without any pullback mechanism. 1-Way and 2-Way springs exhibit different pulling forces and other characteristics; we advise trying both to see which suit your needs best for your specific application.
