Laser cutting: Laser cutting is an efficient and precise processing method in modern manufacturing, widely used in cutting and forming metal sheets. During the laser cutting process, high temperatures will cause the metal to come into contact with air, which will easily cause oxidation and affect the cutting quality and precision. Using nitrogen as an auxiliary gas can form a protective atmosphere during the cutting process to prevent metal oxidation, thereby ensuring a smooth and neat cutting edge and improving processing precision and product quality. Especially in some high-demand application scenarios, such as aerospace, precision instrument manufacturing and other fields, the requirements for cutting quality and precision are extremely high, and the application of nitrogen is particularly important.

Tire inflation: The use of nitrogen has become a standard practice for high-performance and racing vehicles. Compared with ordinary air, nitrogen molecules are larger and penetrate more slowly, so inflated tires can better maintain stable pressure. This is particularly important for high-performance vehicles, as changes in tire pressure can directly affect the vehicle's handling performance and driving safety. In addition, the chemical inertness of nitrogen means that it will not promote oxidation of the inner wall of the tire, thereby extending the service life of the tire and reducing the frequency of maintenance and replacement. Tires inflated with nitrogen perform better in environments with large temperature changes, avoiding tire pressure fluctuations caused by thermal expansion and contraction, and providing additional protection for long-distance travel and high-speed driving.

In component manufacturing: The application of nitrogen is also crucial. In the process of automobile manufacturing, many parts need to be processed in a high temperature environment, such as welding, forging and heat treatment. Nitrogen can be used as a protective gas to provide an inert environment to prevent metals from reacting with oxygen in the air at high temperatures, resulting in oxidation and contamination. This not only improves the surface quality and mechanical properties of parts, but also extends the service life of equipment and reduces scrap rate and production costs caused by oxidation and contamination. Especially when producing high-precision and high-strength parts, the protective effect of nitrogen is more significant.

Providing an inert protective atmosphere: During the cooling and solidification process, the surface of glass products is also susceptible to oxidation and contamination. By using nitrogen to create an inert environment, oxidation and other chemical reactions can be effectively prevented, ensuring the smoothness and transparency of the glass surface. This is especially important for the manufacture of high-quality optical glass, display glass, and other high-end glass products. In addition, the protective effect of nitrogen can also extend the service life of glass manufacturing equipment, reduce maintenance and replacement frequency, thereby reducing production costs and improving production efficiency.
