Why is titanium material so popular?

Why is titanium material so popular?

Mainly by its three special functions:

1. Shape memory function

It refers to the ability of Ti-50% Ni (atomic) alloy to restore its original shape under certain temperature conditions. This material is called shape memory alloy.

2. Superconducting function

Refers to NbTi alloy. When the temperature drops to close to absolute zero, wires made of NbTi alloy will lose resistance. If any large current passes through, the wire will not heat up and consume no energy. NbTi is called a superconducting material.

3. Hydrogen storage function

Refers to Ti-50%Fe (atomic) alloy, which has the ability to absorb a large amount of hydrogen. Using this characteristic of TiFe, hydrogen can be stored safely, that is, it is not necessary to use steel high-pressure gas cylinders to store hydrogen. Under certain conditions, TiFe can be stored to release hydrogen, which is called an energy storage material.
