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.
1. Low-strength titanium alloys are mainly used for corrosion-resistant titanium alloy sheet, and other titanium alloys are used for structural parts called structure titanium alloys.
2. Ordinary-strength titanium alloys (~500MPa), mainly including industrial pure titanium, TI-2AL-1.5Mn (TCI), and Ti-3AL-2.5V (TA18), are widely used alloys. Due to its good price formation performance and weldability, it is used to manufacture various aerospace sheet parts and hydraulic pipes, as well as civilian products such as bicycles.
3. Medium-strength titanium alloy (~900MPa), the typical alloy is Ti-6Al-4V (TC4), which is widely used in the aerospace industry.
4. High-strength titanium alloy is composed of near-beta titanium alloy pipe and meta-stable beta titanium alloy with a tensile strength at room temperature above 1100MPa. It is mainly used to replace high-strength structural steel commonly used in aircraft structures. Its typical alloys are Ti-13V- 11Cr-3Al, Ti-15V-3Cr-3Sn (TB5) and Ti-10V-2Fe-3Al.
