Product Usage: Argon is a widely used Noble gas in industry. Its properties are very inactive, neither able to burn nor support combustion. In the sectors of aircraft manufacturing, shipbuilding, atomic energy industry, and mechanical industry, argon is often used as the welding protective gas for special metals such as aluminum, magnesium, copper and their alloys, and stainless steel, to prevent the welded parts from being oxidized or nitrided by air.

In the field of metal smelting, oxygen and argon blowing is an important measure for producing high-quality steel, with an argon consumption of 1-3m³ per 1T of steel produced。 In addition, argon is also needed as a protective gas for the smelting of special metals such as titanium, zirconium, and germanium, as well as in the electronic industry.
