In recent years, the total output value of China's new materials industry has continued to rise, demonstrating a strong momentum of development. The relevant departments of the state are committed to optimizing the innovation and development ecology of new materials, and continuously promoting the growth and progress of the new materials industry. As the material cornerstone of weapons and equipment, the importance of military materials is self-evident. In the military field, new military material technology is the core of sophisticated weapons and equipment, and is an indispensable part of military high technology. Therefore, accelerating the progress of new military material technology has become a key prerequisite for all countries to maintain military superiority.
Titanium alloys, based on titanium and with the addition of other alloying elements, exhibit excellent corrosion resistance, fatigue resistance and high specific strength. In the aerospace field, titanium alloys play an indispensable role in equipment weight reduction, so they are widely used in aero engines, aircraft manufacturing and missile technology. Titanium alloy, as the metal material with the highest specific strength, can perfectly meet the high-speed and high-maneuverability challenges of advanced fighters, while ensuring the structural strength of the airframe while reducing weight, and has excellent high-temperature resistance. These requirements have led to significant reductions in aircraft weight and structural efficiency.
Since the end of the 60s of the 20th century, the amount of titanium used in military aircraft has continued to rise. Among them, the titanium content of the American F-22 fighter is as high as 41%, and the Chinese J20 has achieved a breakthrough of 35%. With the continuous increase in the production capacity and installation scale of fifth-generation fighters, as well as the acceleration of the research and development of sixth-generation aircraft in many countries around the world, the market demand for military high-end titanium alloys will continue to expand.
With the evolution of modern warfare, the Army's needs for weapon systems are becoming more and more diverse, including powerful weapons, long range, high accuracy, and rapid reaction capabilities. Among these needs, new material technologies are particularly crucial, especially in the lightweighting of self-propelled gun turrets, components, and materials for light metal armored vehicles. Titanium alloys are widely used in these fields due to their excellent properties and wide range of resources. For example, the use of titanium alloy in the 155 artillery brake not only significantly reduces the weight, but also effectively reduces the gravitational deformation of the gun barrel, thereby improving the shooting accuracy. In addition, the complex shape components of the main battle tank and helicopter-anti-tank multi-purpose missiles are often made of titanium alloy, which not only meets the performance requirements, but also reduces the processing cost.
