Dynalloy, Inc. is a manufacturer of shape memory alloys specially made to be used as actuators. In other words made to provide movement much like a solenoid or motor would for many many cycles. The high repeatability of such applications requires a dependable, reliable and very repeatable material.

Dynalloy, Inc. manufactures these nickel titanium alloys as small wires under the trade name of FLEXINOL® to differentiate them from other shape memory alloys which do not have these same properties.

FLEXINOL® actuator wires contract much like little muscles a distance of approximately 4-5% when they are "on" and relax when they are "off".
