Titanium alloy is a very light material, it has small elasticity, high strength, and also has a good heat resistance and corrosion resistance. It is one of the important materials used to manufacture weapons and equipment, and it is also a relatively common material currently used by nuclear submarines. Whether it is Chinese nuclear submarines or US and Russian nuclear submarines, they use a large amount of titanium alloy materials in their own submarine construction. The proportion of titanium alloy materials used is also very different. For example, Russian nuclear submarines like to use a lot of titanium alloy materials, while the US military nuclear submarines use titanium alloy materials relatively low-key. China has abundant reserves of titanium alloy resources, and the reserves of ilmenite ore rank first in the world. The moderate use of titanium alloys on nuclear submarines will greatly improve the hardware performance of China's nuclear submarines.
Titanium alloy has a huge advantage for China's nuclear submarines. In particular, China has made great achievements in the use of titanium alloy materials. The C919 large passenger plane and the CZ-5 high-thrust launch vehicle all use key rare metal materials such as titanium and titanium alloys. Titanium alloy, as one of the important materials for weapons manufacturing, is mainly used to manufacture rockets, missiles and other weapons components or engine and compressor parts. Not only that, but it can also be used to make delicate parts and even submarines.
Countries in the world are working hard to study the casting technology of titanium alloys, but the three countries with the highest achievements are the United States, Russia and China. The United States occupies a leading position in this regard, but because the domestic production of titanium is not high, it usually only uses titanium alloys in key and necessary places. Russia has continued to develop in the field of titanium alloy technology based on the former Soviet Union's experience in manufacturing many nuclear submarines from titanium alloys. And China, as a country that developed military science and technology late, is not lost to other military powers. According to records, my country has used nearly 20% of the titanium alloy material in the manufacture of the J-20 to increase the life of the airframe.
This is our great power weapon, and it will play an important role in the future. It also fully proves that our country has begun to grow stronger in industry and gradually rise in military power.
