What is Nitinol Shape Memory Wire?
Nitinol Shape Memory Wire is made up of nickel-titanium alloys, which possess the unique ability to remember their original shape when they are deformed. The alloy is also highly corrosion-resistant, making it an ideal material for aerospace applications. Nitinol Shape Memory Wire is an innovative material that exhibits shape memory behaviour. Nitinol is a nickel-titanium alloy that can “remember” its original shape and return to it when heated above a specific temperature. This property is due to the unique crystal structure of the alloy, which allows it to undergo a reversible phase transformation.
Applications of Memory Wire in the Aerospace Industry
The ability of Nitinol Shape Memory Wires to be used like an actuator is one of their most appealing aspects. As actuators, these wires are used in space vehicles and aircraft by allowing them to move from one state (e.g., closed) to another (e.g., open). For example, these wires use latch mechanisms for doors on aircraft or for landing gear deployment systems on spacecraft, allowing them to open and close quickly despite extreme temperatures and pressures encountered during takeoff and landing. Additionally, these wires are used as sensors for aircraft or spacecraft to detect changes in temperature or pressure during flight operations.
Properties of Nitinol Shape Memory Wire
Shape Memory Effect: Nitinol Shape Memory Wires can “remember” their original shape and return to it when heated above a specific temperature, even after deforming it.
