Argon

A safe and reliable supply of pure argon and argon gas mixtures

Air Liquide supplies argon and argon mixtures in various volumes and purities. Argon is used as a protective atmosphere for a large number of industrial processes, such as electronics and automotive parts manufacturing.

Argon pure gas and argon mixtures are commonly used in shielded arc processes for welding aluminum, stainless steel, bronze and copper. Used as a shielding gas in arc welding, root shielding and plasma cutting applications, argon provides an inert atmosphere to prevent oxidation or other chemical changes that would be detrimental to the weld. In steel manufacturing, argon prevents interaction between liquid metal and the surrounding atmosphere. Air Liquide offers ARCAL™ brand pure argon and argon mixtures, with four ready-to-weld products that cover practically any welding application. Each one is designed to be easy to use, reliable and efficient, no matter when and where you need it.

For use in laboratories, ultra-high purity ALPHAGAZ™  brand argon is engineered for gas chromatography, zeroing and other analytical and process control applications. 

Air Liquide supplies argon in varying volumes to meet the needs of different industries. Compressed gas cylinders of ALPHAGAZ™ brand argon come equipped with SMARTOP™ and an open cap design.
