Nitinol Welded nitinol Actuator Loop Ring Belt 80°C SMA Memory Alloy FUXUS®
This actuator is made of nitinol Shape Memory Alloy with a recovery temperature of about 80°C
In the cold state, it can be deformed with little effort.
When heated above 80 C, it jumps back into stored form.
In this case, the wire was stored to be straight.
The wire was then welded to a ring or circular shape.
The force acting upon the return in the straight line can be used as a driving force for a so-called heat engine (heat engine) .
There are many such applications worldwide.
Wire diameter 1mm
