Nickel titanium alloy is a shape memory alloy and belongs to metallic materials. It has the following characteristics and application areas:

1、 Characteristics

Shape memory effect: Under certain temperature conditions, it can remember its original shape. When external force is applied to the alloy to cause deformation, it will automatically return to its original shape as long as it is heated to a specific temperature. For example, bending nickel titanium alloy wire into a specific shape can deform freely at low temperatures, but when the temperature rises above its transformation temperature, the alloy wire will quickly return to its initial bent shape.

Superelasticity: Within the range of elastic deformation, it can withstand much larger deformations than ordinary metal materials without permanent deformation. If the eyeglass frame is made of nickel titanium alloy, even if it is greatly twisted by external force, it can quickly restore its original state after removing the external force.

Good biocompatibility: minimal interaction with human tissues, without causing significant immune or toxic reactions. So it is widely used in the medical field, such as for manufacturing medical devices implanted in the human body.

Corrosion resistance: With excellent corrosion resistance, it can maintain stability in various chemical environments and is not easily corroded. This allows it to function normally even in some harsh working environments.

2、 Application Fields

Medical field: used for manufacturing various medical devices, such as vascular stents, orthodontic wires, artificial joints, etc. Vascular stents utilize their shape memory effect and superelasticity to expand and maintain an open state within blood vessels, effectively supporting narrow blood vessels; Orthodontic wires can maintain stable elasticity in the oral environment, gradually applying gentle orthodontic force to achieve teeth correction.

Aerospace field: can be used to manufacture some components of aircraft engines, wing folding mechanisms of aircraft, etc. By utilizing its shape memory properties and superelasticity, it is possible to achieve compact design and reliable functional implementation of components, while reducing component weight and improving the performance of aerospace vehicles.

In the field of electronics, nickel titanium alloys can be used to manufacture components such as micro relays and sensors in electronic devices. For example, nickel titanium alloy components in micro relays can utilize their shape memory effect to achieve circuit switching control, which has the advantages of fast response speed and high reliability.

In daily life, it is commonly found in high-end eyeglass frames, mobile phone antennas, watch straps, and other products. The eyeglass frame utilizes its super elasticity and corrosion resistance to provide users with a comfortable wearing experience and a long service life; The mobile phone antenna is made of nickel titanium alloy, which can ensure signal transmission performance while having good flexibility and deformation resistance.
