NiTinol-titanium metal memory rings, their types and market applications
Type
- Classified by memory effect: One-way memory effect nitinol metal memory ring, only exhibits shape memory phenomenon during heating, deforms at low temperature, and recovers its original shape after heating; Two-way memory effect memory ring, recovers the high-temperature phase shape when heated, and recovers the low-temperature phase shape when cooled; Full-way memory effect memory ring, recovers the high-temperature phase shape when heated, and becomes a low-temperature phase shape with the same shape but opposite orientation when cooled.
- Classified by fine-tuning of alloy composition: There are Ni-Ti-Cu, Ni-Ti-Co, Ni-Ti-Fe, Ni-Ti-Nb, etc. The addition of different trace elements can make the memory ring have certain differences in shape memory temperature, superelasticity and other properties.
Market Application Scenarios
- Medical field: As a vascular stent, it can open up narrowed parts in blood vessels and maintain vascular patency; used to manufacture urethral stents to help solve problems such as urethral stenosis; it can also be made into thrombus filters to capture thrombi in the blood and prevent them from flowing with the blood to cause more serious embolism.
- Aerospace field: As a device for balancing helicopter blade pitch, it can automatically adjust the blade pitch according to the flight status, improving flight performance and stability; it can also be used to manufacture lunar antennas, which are folded for easy carrying at low temperatures and automatically unfold after reaching the moon under sunlight heating.
- Daily consumer field: Used to make eyeglass frames, using its superelasticity and shape memory characteristics, making the eyeglass frames less prone to deformation and more comfortable to wear; in bra making, nitinol memory steel rings can replace traditional steel rings, providing good support while automatically adjusting with body movement and temperature changes, making them more comfortable to wear.
- Electronics field: It can be used to manufacture connecting parts of electronic devices, such as wiring connectors inside mobile phones and computers, to ensure the stability and reliability of the connection, and it can also be used to make temperature sensors to control the on and off of the circuit according to temperature changes, etc.
