Argon (Ar) is a colorless, odorless, non-reactive inert gas. In high concentrations, it has a suffocating effect. Since Argon is an atmospheric gas (0.93% by volume), it is usually derived by air separation.


  • Pure Argon gas is an inert shielding and welding gas, most commonly used for most TIG welding applications of aluminum and stainless steel copper and cast iron.
  • Medical applications: in laser devices to destroy cancer cells.
  • For Making Semiconductors.
  • Applications in running analyzers, running spectrometers, food analysis, nuclear technology, Polymer-composite technology.
  • Application in plasma cutting of black and non-black needle cartridges (cutting).
