How are titanium alloys classified according to strength?

Titanium alloys can be classified into low-strength titanium alloys, ordinary strength titanium alloys, medium strength titanium alloys, and high-strength titanium alloys based on their different strengths. The following are the 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 has a room temperature tensile strength of over 1100MPa, which is characterized by β Titanium alloy and metastable β Titanium alloy composition is mainly used to replace the commonly used high-grade structural steel in aircraft structures. Its typical alloys include Ti-13V-11Cr-3Al, Ti-15V-3Cr-3Sn (TB5), and Ti-10V-2Fe-3Al.
