Nitinol flat wire is a special alloy wire made of nickel-titanium alloy. The alloy wire has a memory effect and superelasticity, allowing it to return to its original shape after being deformed. It is widely used in industries such as medical equipment, automotive, aerospace, electronics, home furnishing, and consumer goods. For example, it can be used to make brackets, internal repairs to pipes, solar panels, power tools, springs, eyeglass frames, and locksmith tools, among others. It is widely used because of its advantages such as corrosion resistance, lightweight and high strength.
Nitinol is made from an alloy of nickel and titanium, which has properties such as shape memory and superelasticity. Nitinol wire is similar to Nitinol in other shapes, but because it is flat, it is more suitable for certain applications.
type of nitinol flat wire
1. Superelastic Nitinol flat wire:
Superelastic nitinol alloy means that nitinol itself has self-restoring properties. When you bend a nitinol super-elastic nitinol flat wire, it will return to its original shape.
2. Shape Memory of Nitinol flat wire:
Shape memory alloy means that when it is in its martensitic form, it can easily deform into a new shape. However, when the nitinol memory alloy is heated to its transformation temperature, the nitinol shape memory alloy reverts to austenite and regains its original shape with great force.

Physical and chemical properties of nitinol flat wire
physical and chemical properties of nitinol flat wire
In general, nitinol flat wire is an alloy with special physical and chemical properties, its shape memory and superelasticity make it widely used in many different applications
Physical propertie
- Density: about 6.45 g/cm3
- Melting point: about 1300-1310°C
- Conductivity: good conductivity
- Corrosion resistance: corrosion resistance, good chemical stability
- Mechanical properties: high specific strength and high specific stiffness, with good bending resistance and tensile and compressive properties
Chemical properties
- Good chemical stability and corrosion resistance, resistant to most common acids, alkalis, and salts.
- Sensitive to water, oxygen, and hydrogen sulfide, prone to corrosion and loss of elastic properties under these conditions.
- Thermal stability: Nitinol alloy flat wire can restore its original shape below approximately 410°C, but above this temperature, it may change its shape or cause thermal damage.
