Niti Spring

NiTi Spring

This NiTi Spring is made from shape memory alloy (Nickel – Titanium).

At room temperature this spring is soft enough to pull out to approximately 50mm by applying a small force.

When heated to 70°C by passing an electric current through it (or by other means such as hot water or a heat gun, etc), the spring contracts to its original length with a useful pulling force (equivalent to lifting a 0.5kg weight).

Spring weight: 1.1g

Dimensions:

20mm (when closed).

5.5mm external diameter.

4mm internal diameter.
