Argon Gas Technical Specifications
Argon is an inert noble gas that is colorless, odorless, and non-flammable under ambient conditions. It is separated from liquid air and, due to its high purity, is widely used in welding, steel production, and laboratory applications.
- Inert and non-flammable gas
- Higher density than air (heavier than oxygen and nitrogen)
- Purity up to 99.999%
- Boiling point: −185.8°C
- Widely used in welding, steelmaking, and laser equipment

Safety & Storage
Argon is inert but can displace oxygen in confined spaces.
Cylinders must be stored away from heat sources and kept leak-free.
When handling liquid argon, use protective gloves and face shields.
