Titanium alloys can be roughly divided into low-strength titanium alloys, ordinary 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 alloys. Other titanium alloys used for structural parts are called structural titanium alloys.
2. Ordinary strength titanium alloy (~500MPa), mainly including industrial pure titanium, Ti-2AL-1.5Mn (TCl) and Ti-3AL-2. 5V (TA18) is a widely used titanium alloy. Due to its high cost performance and good weldability, it is used to manufacture various aviation sheet parts and hydraulic pipes. It is also often seen in civilian products such as bicycles.
3. Medium-strength titanium alloy (~900MPa), typically Ti-6AI-4V (TC4) titanium alloy, which is widely used in aerospace and other industrial fields.
4. High-strength titanium alloy, whose tensile strength at room temperature is above 1100Mpa, is composed of nearly β titanium alloy and metastable β titanium alloy, and is mainly used to replace the commonly used high-degree structural steel in aircraft structures. Its typical alloys There is Ti-13V-11Cr-3AI. Ti-15V-3Cr-3Sn (TB5), Ti-10V-2Fe-3AI.
Titanium alloys of different strengths are very different in terms of price and performance. During the selection process, customers need to choose the appropriate strength titanium alloy according to the actual use environment.
