Nickel titanium alloy, as the name suggests, is mainly composed of two metal elements, nickel (Ni) and titanium (Ti), with an atomic ratio usually close to 1:1.
In recent years, with the continuous advancement of technology, the application of nickel titanium memory alloys in microelectronics and optical devices, sensors, energy, aerospace and other fields has been constantly explored and expanded.
Nickel titanium alloy is mainly composed of nickel (Ni) and titanium (Ti). In the most common nickel titanium alloys, the mass percentage of nickel is usually around 55%, with the rest being titanium.
