Nitinol SMA tube opens the possibility of targeted hydraulic activation by controlling the temperature of a fluid through the tube.

The maximum tube length is 500mm. It is soft and bendable at room temperature, and will return to straight when heated to 40°C or above. The wall thickness is  0.5mm. Full 500mm tube weight: 28 grams. We can cut the tube in half to help with ordering at a lower cost, but purchasing the full length is highly recommended.

Through a sophisticated, tedious drawing process, we are able to offer you tubes that are oxide free with superior memory function of any nitinol tube product in the industry.

These tubes allow for the most effective way to deliver heat activation to the alloy since a simple pump mechanism can be used to deliver a carrier fluid to the inside of the tube.

The tube is pre-treated with shape memory set as straight. Complete austenite Af occurs at 40°C.
