Helium 4.6

Helium is inert and lighter than air. This industrial grade is available in a range of volumes either as a compressed gas or a cryogenic liquid


Helium 4.6 is used extensively as a shielding gas, resonator gas and for lifting blimps or aerostats. In cryogenic liquid format, liquid helium is often abbreviated to 'LHE'.


  • Used as a resonator gas in laser cutting
  • In the welding industry as an inert shielding gas for arc welding
  • Alongside helium leak detectors for checking leak tightness in pipelines
  • For lifting airships and blimps
