Titanium alloys can be classified into low strength titanium alloys, ordinary strength titanium alloys, medium strength titanium alloys, and high-strength titanium alloys according to their different strengths. The following are specific classification data:

1. Low strength titanium alloys are mainly used for corrosion-resistant titanium alloys, while other titanium alloys used for structural components are called structural titanium alloys.

2. Ordinary strength titanium alloys (~500MPa), mainly including industrial pure titanium, TI-2AL-1.5Mn (TCl), and Ti-3AL-2.5V (TA18), are widely used alloys. Due to its good price performance and weldability, it is used to manufacture various aviation sheet metal parts and hydraulic pipes, as well as civilian products such as bicycles.

3. Medium strength titanium alloy (~900MPa), typical alloy is Ti-6Al-4V (TC4), widely used in the aerospace industry.

4. High strength titanium alloy is composed of near beta titanium alloy and metastable beta titanium alloy with a tensile strength of over 1100MPa at room temperature. It is mainly used to replace high-grade structural steel commonly used in aircraft structures. Its typical alloys include Ti-13V-11Cr-3Al, Ti-15V-3Cr-3Sn (TB5), and Ti-10V-2Fe-3Al.
