Your need: perform nitinol alloy analysis
Nitinol is a memory metal alloy composed mainly of nickel (55%) and titanium (45%). It takes its name from the elements that compose it (Nickel and Titanium) and from the laboratory where it was developed (Naval Ordnance Laboratory). Nitinol is particularly known for its two unique properties: shape memory and super-elasticity.
What are the properties of Nitinol?
Nitinol is an alloy with a unique ability to remember its original shape. After deformation at low temperature, it can return to its original shape when heated above a certain temperature. This property is due to a reversible phase transformation between two crystalline structures: martensite (low temperature) and austenite (high temperature).
At temperatures slightly above the transformation temperature of martensite, nitinol can be reversibly deformed under mechanical stress, returning to its original shape once the stress has been removed. This gives it an elasticity far superior to that of conventional metals.
Analysis of the composition of Nitinol: an essential quality control
The chemical composition analysis of nitinol verifies the presence and concentration of critical alloying elements such as nickel and titanium, thus ensuring compliance of materials for safety and performance-critical applications.

FAQ
Nitinol is used in many areas because of its unique properties:
Medical devices:
Cardiovascular stents: Nitinol stents can be compressed for insertion into a blood vessel and return to their original shape to keep the vessel open.
Orthodontic wires: Nitinol orthodontic wires exert a constant force on the teeth, facilitating their alignment.
Surgical instruments: Nitinol is used to make catheter clamps and guides because of its flexibility and ability to regain shape.
Aerospace industry:
Connectors and fasteners: Nitinol is used for connections that need to be robust but flexible.
Deployment systems: Used in mechanisms that require accurate and reliable deployment, such as satellite dishes.
Industrial applications:
Actuators and sensors: Nitinol is used in devices where mechanical action is required in response to a temperature change.
Robots and automation: Nitinol components can be used to create precise, controlled movements.
Benefits:
- Biocompatibility: Nitinol is well tolerated by the human body, making it ideal for medical applications.
- Corrosion resistance: Good corrosion resistance, especially in biological and marine environments.
- Durability: High capacity to withstand deformation cycles and regain its original shape.
Limitations:
- Cost: Nitinol is relatively expensive compared to other metal alloys.
- Manufacturing process: The methods of manufacture and heat treatment must be carefully controlled to obtain the desired properties.
- Temperature limits: Nitinol’s performance is limited by specific temperature ranges, beyond which its shape memory and super-elasticity properties are altered.
