Cylinder Identification

Cylinder colour (to AS 4484): Peacock blue body, shoulder and neck.


  • Colourless, tasteless and odourless

  • Inert to all materials at all temperatures and pressures

  • Heavier than air, argon will collect in low-lying areas, ducts and drains

  • An asphyxiant

  • Lower thermal conductivity than most other gases

  • Low thermal conductivity acts as an insulator and will not transfer heat efficiently


  • All the major applications of argon are related to the production, processing and fabrication of metals. 

  • The role of argon is nearly always to exclude atmospheric air from contact with metal alloys.

  • Purging gas to protect weld areas, such as the inside of pipes during welding is a good example.

  • Major component in most shielding gas mixtures for arc welding and cutting due to low ionising potential

  • The predominant gas used in shielding gases as it forms a very good shield due to the high density and total inertness

  • Used on a wide range of ferrous and non-ferrous materials for welding and cutting

  • Fills the inter-space in double glazed windows
