NiTiNol wire
Nickel - Titanium Nitinol Memory Wire
What is NiTiNol alloy.
DLX alloy produce nitinol wire. it was commonly used in special applications, enabling unusual design characteristics while maintaining all of the capabilities of standard metal wires.
Nitinol’s transition temperature - or the conditions under which the alloy can change shapes - is repeatable over time as well, making the material ideal for use over many cycles. Said plainly, nitinol can undergo many deformation-heating-reversion cycles, which means nitinol is a smart choice of material when long-term application is the optimal outcome. Typically, nitinol becomes transformable at 180°F, but these variables can be higher or lower. As a matter of fact, nitinol’s transition temperatures vary depending upon the precise composition of the nitinol in use, as well as how it was heat-treated at the time it was manufactured.
.
Superelastic Nitinol is commonly used in medical devices. Transformation temperatures for superelastic grades are between -20°C and 22°C [-4°F and 71.6°F].
Shape memory Nitinol is commonly used for actuators and other industrial applications. Transformation temperatures for shape memory grades are between 22°C and 80°C [71.6°F and 176°F], with some grades offering temperatures greater than 85°C [185°F].
