Argon is a non-flammable, colorless, odorless and tasteless gas slightly heavier than air. It is non-toxic but do not support life and can act as asphyxiant. We offer argon gas and liquid argon of purity 99.999%. It can be mixed with other gases to create specialty blends as needed. Argon gas is used in welding applications such as the welding of specialty alloys, and in the production of light bulbs and lasers. It can also be used as an inert shield gas to enhance arc stability of gas metal arc welding. In metal production, argon is used to prevent oxidation during processing.
