Shape Memory Alloy Manufacturing Enables Cross-industry Applications

The unique properties of TiNi-02 nickel-titanium alloy wire make it an attractive material of choice for manufacturing products and components in various industries.

Aerospace In the aerospace industry, shape memory alloys are used to develop lightweight, quiet, and efficient designs: these three factors - straight is the point of aircraft design. Components such as variable-section fan nozzles, shock absorbers, and actuators are made of shape memory alloy materials. These devices are austenitic at normal temperatures and transform to intensity (and the desired shape) upon cooling due to temperature changes caused by airflow around the aircraft or changes in ambient temperature during normal flight. The temperature changes that cause the phase transition can be produced in different ways, either by an electronic component heating the SMA device or by excess air in other parts of the aircraft.

The latest technological innovation in shape memory materials is wing deformation technology. Shape memory alloys were used to develop an adaptive wing that flexes and changes shape during flight.

Car:

Motor vehicles on the ground also benefit from shape memory alloys, but their use is more in comfort and ease of use than in handling. For example, some cars have shape memory alloy valves for airbags in the seats, and under a certain pressure, the lumbar support on the seat can perfectly fit the driver or passenger's waist. In addition, shape memory alloys are used to make actuators that make car trunks easier to close, as well as valves to control noise and vibration in the engine (an important performance indicator in the automotive industry), improving noise, vibration, and Acoustic roughness.

Architecture:

Another area of application for shape memory alloys is architectural design. For example, SMA rods in concrete beams help to prestress bridges or buildings. On a smaller scale, TiNi-02 nitinol wire can be used to enhance the reliability of pipe fittings in piping systems.

Medicine:

The application of shape memory alloys in biomedicine could reduce the need for medical interventions for patients. Medical stents, for example, can be implanted in arteries to improve blood flow in patients with heart disease in a minimally invasive way. Microactuators and artificial muscles rely on shape-memory alloys to create mechanical prosthetic organs that help amputees move more freely. Cardiac stents are a minimally invasive cardiac treatment method, usually made of shape memory alloy materials. (Note: The picture is taken from the teaching case of plastic deformation during the expansion of a biomedical stent, which does not contain shape memory alloys, and is here purely to illustrate the application discussed above). On a smaller scale, shape memory alloys are also used in orthodontics, such as braces; and optometry, such as glasses. If the frame is made of a shape-memory material, it doesn't need to be replaced even if it bends, you can heat the frame to restore it to its original shape.
