Nitinol Actuator Wire

Nitinol is an alloy of Nickel and Titanium (in about a 50/50 composition). It is manufactured by several companies, including Dynalloy, SAES Group, Fort Wayne Metals and Furukawa Techno Material.

The wire is manufactured in multiple sizes from 0.0001″ to 0.020″ diameter. The companies offer multiple transition temperatures of 70C, 90C and NiTiPd alloys that transition at 170C.

Nitinol wire can last for millions of cycles if it is used properly. Using it properly can be very tricky. Contact us today for assistance with your Nitinol development. See many examples below of different uses for Nitinol wire in actuators.

See other possibilities for use of nitinol actuators at our home page. Flexinol nitinol actuator wire is one of the best brands of wire for use in tiny actuators. Solenoid replacement is a common use for nitinol actuators.

Nitinol Pneumatic Cylinder Replacement

Nitinol Pneumatic Cylinder Replacement

This long stroke, high speed, prototype SMA actuator was designed for Sony to remove DVD's that did not pass quality control from an assembly line. Mineral oil is used in the body of this actuator to enhance cooling of the Nitinol. This actuator features 8" of 0.010"...

Nitinol Actuator Over-Stress Protection

Nitinol Actuator Over-Stress Protection

Nitinol actuators are very easily damaged if the stress exceeds roughly 40 ksi or if the temperature exceeds 150 degrees C. This is a demonstration of mechanical over-stress protection in which flexures deflect very short distances when an engineered or pre-determined...
