Nitinol Smart Shape Memory wire an application a day

Nitinol is invented in Naval ordinance laboratory and is widely used in defense applications.

Flexinol a form of Nitinol programmed to shorten on power supply is used as actutator in military products. The best example of application in this field is undoubtedly the Cryofit hydraulic coupling. These anchors are manufactured as sleeves just smaller than the metal pipe to join. Its diameter is expanded during martensite and, after heating to austenite, the tubes shrink and hold tightly. The tubes mean that the coupling cannot recover the diameter with which it was made, and the tension that is generated is in many cases is higher than that of a weld.
