Gazy techniczne - argon


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

CAS Number: 7440-37-1
UN1006 (gas); UN1951 (liquid refrigerated)

Argon pure gas and argon gas 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.

Argon is also used as a protective atmosphere for a large number of industrial processes, including steel manufacturing, metal fabrication, automotive parts manufacturing, to inflate car airbags and serves as a non-reactive thermal blanket in double glazed windows.

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