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 different strengths. The following is the specific classification data:
1. Low-strength titanium alloy, mainly used for corrosion-resistant titanium alloy, other titanium alloys are used for structural parts called structure titanium alloy (structure titaniumalloy).
2. Common strength titanium alloy (~ 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 forming performance and weldability, it is used to manufacture various aerospace plate 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), widely used in the aerospace industry.
4. The high-strength titanium alloy is a room-temperature tensile strength above 1100MPa, which is composed of near-beta titanium alloy and meta-stable beta titanium alloy. It is mainly used to replace the high-level structural steel commonly used in aircraft structures. 11Cr-3Al, Ti-15V-3Cr-3Sn (TB5) and Ti-10V-2Fe-3Al.
