NiTi Memory Wire

Product Code : SCL-CLE-12874
This nickel/titanium (NiTi) alloy initially
'remembers' that it should be straight. If it is bent into a different shape
and then dropped in very hot water (90°C), it springs back to its original
straight condition. It will repeat this behaviour any number of times.
The wire can also be heat treated to remember different shapes. It simply has
to be held in the desired shape and then heated to 500°C in a small oven for a
few minutes.
This means that pupils can now get involved in creating smart springs and other
components that a few years ago would have challenged front line researchers.
Size: 0.50mm diameter x 1m length.
