Introduction to Classification, Properties, and Applications of Commonly Used Titanium Alloy Grades in Industry

Titanium alloy has become a core structural material in aerospace, marine engineering, high-end equipment, new energy and other fields due to its comprehensive characteristics of lightweight, high strength, high temperature resistance, fatigue resistance, and corrosion resistance. Unlike pure titanium, titanium alloys optimize their mechanical properties by adding alloying elements such as aluminum, vanadium, and molybdenum. The market has a wide variety of grades, with significant differences in strength, toughness, and high temperature resistance among different grades. They are directly suitable for different industrial conditions and are key materials for high-end precision equipment manufacturing.

Domestic industrial titanium alloys are mainly divided into three categories: alpha type, alpha+beta type, and beta type. The mainstream commonly used grades include TC4, TC11, TA15, TB2, etc. The performance and application scenarios of each grade are clearly divided. Among them, TC4 (Ti-6Al-4V) is currently the most widely used universal titanium alloy, belonging to the α+β type alloy. It has balanced comprehensive performance, high strength, good toughness, weldability, easy processing, and is suitable for high temperature, high pressure, and heavy load conditions. It is widely used in aviation structural components, marine equipment, precision machinery, and medical instruments, and is the mainstream choice for industrial material selection.

TC11 titanium alloy has excellent high temperature resistance and creep resistance, and stable performance under long-term high temperature conditions. It is mainly used in high-temperature and heavy-duty components such as aircraft engines and high-end thermal equipment. TA15 titanium alloy has outstanding welding performance and strong structural stability, and is widely used in aviation welding structural components such as aircraft skins and load-bearing frames. The TB series β - type titanium alloy has extremely high strength and good cold forming performance, suitable for high-end precision forging and high-strength elastic component manufacturing, meeting the needs of high-precision and cutting-edge industrial production.

There are significant differences in the adaptation scenarios of different titanium alloy grades. Industrial material selection needs to be accurately matched based on working conditions, temperature, load strength, and processing technology in order to balance equipment stability and production costs.
