Titanium alloys can be divided into low strength titanium alloys, ordinary strength titanium alloys, medium strength titanium alloys, and high strength titanium alloys according to their different strengths. The specific classification data are as follows:
"Low strength titanium alloys are mainly used for corrosion resistant titanium alloys, while other titanium alloys are used for structural components, which are called structural titanium alloys.".
Ordinary strength titanium alloys (~500MPa), mainly including industrial pure titanium, TI-2AL-1.5Mn (TCl), and Ti-3AL-2.5V (Gr.9), are widely used alloys. Due to its good price formation performance and weldability, it is used for manufacturing various aviation plate parts, hydraulic pipes, and other civil products such as bicycles.
Medium strength titanium alloy (~900MPa), typically Ti-6Al-4V (Gr.5), is widely used in the aerospace industry.
High strength titanium alloy has a tensile strength above 1100 MPa at room temperature β Titanium alloy and metastable β Titanium alloy composition is mainly used to replace the high degree structural steel commonly used in aircraft structures. Typical alloys include Ti-13V-11Cr-3Al, Ti-15V-3Cr-3Sn (TB5), and Ti-10V-2Fe-3Al.
