Titanium alloys were widely used in the aerospace field in the early days, mainly in the production of aircraft engines or pneumatic components. Later, with the continuous development of technology, titanium alloys have entered the lives of ordinary people, and titanium alloys are also found in factories or household devices. Now countries and institutions are competing to develop new titanium alloys, so that it has the characteristics of low cost and high performance, and the new development of titanium alloy manufacturers in recent years is mainly concentrated in the following aspects.

(1) Medical titanium alloy.
Titanium alloy has a small density and good biocompatibility, is an ideal medical material, and can even be implanted in the human body, previously used in the medical field of titanium alloys containing vanadium and aluminum, will cause harm to the human body. However, in the near future, Japanese scholars have developed a new type of titanium alloy, with good biocompatibility, but this alloy has not yet been mass-produced, I believe that in the near future, such high-quality alloys can be widely used in daily life.

(2) Flame retardant titanium alloy.
The titanium base alloy that can resist combustion under a certain pressure, temperature and air flow rate is a resistive titanium alloy. The United States, Russia and China have successively developed new resistance titanium alloys, of which the United States will apply these resistance titanium alloys to the engine, because these titanium alloys are not sensitive to combustion, so it can greatly improve the stability of the engine.

(3) High temperature titanium alloy.
By combining rapid solidification method with powder metallurgy method, titanium alloys prepared by fiber or particle reinforced composite materials have excellent high temperature mechanical characteristics. The use temperature limit of high temperature titanium alloy is much higher than that of ordinary titanium alloy. At present, new high-temperature titanium alloys have been prepared in the United States.
