I spent the last 4 years professionally developing (Nickel, Titanium,
Navel ordnance lab) NiTinol actuators. Real interesting stuff. On a
ft*lb/lb weight it has amazingly high energy density, 1000 time a
electric motor. Power efficiency on the other had is horrible.
This company has a good selection of NiTinol produces and a fairly good
description of the material. One note: Don't believe everything you
read about NiTinol much of the published stuff is just plain wrong.
The medical and dental industry is a big user or the material in what is
called super elastic form. In this form it is a super spring which can
deform with 8% strain. My eye glasses frame are made from the stuff and
are by far the best frames I have ever had. They survived intact 2
years of constant abuse by two under 3 year old girls.
Obligatory metal working content: ITN Energy system makes a work
holding fixture for Jordinson(sp) that uses a NiTinol actuated clamp to
hold palletized machine parts. It replaces hydraulic clamps. Last I
heard it is selling well.
