Buy Helium Gas or Purchase Liquid Helium (He)
Helium is a highly specialized product. It’s chemically inert and non-flammable, with high thermal conductivity, low molecular weight and size, and the lowest boiling point known.
At Praxair, we deliver gas and liquid helium (He) in a variety of purities up to 99.999%. Explore the chart below to view the spec sheets and safety data sheets for our pure helium products and a few of our popular welding mixtures. If you don’t find what you’re looking for, contact us and we’ll manufacture a binary or multi-component helium mixture to meet your unique specifications.

Uses of Helium Gas and Liquid Helium (He) by Industry
From manufacturing to flight, helium is widely utilized throughout the aerospace and aircraft industry. In space flight operations, helium is used to purge hydrogen systems and to pressurize ground and flight fluid systems. It can also provide lift in weather and other surveillance balloons.
Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications. It is also used in combination with argon as a source of inflation in a growing number of airbags.
In combination with oxygen, helium is used in diving to help eliminate nitrogen narcosis, reduce breathing resistance at depth, and shorten decompression stops. Known as heliox, the mixture allows divers to reach greater depths for longer periods of time. The deeper the dive, the higher the concentration of helium, allowing divers to explore more and weld longer.
Helium plays a significant role in the manufacturing of semiconductors, LCD panels, and fiber optic wire. It cools parts and components quickly to enhance throughput, controls the rate of heat transfer to improve productivity and reduce defects, and functions as a carrier gas in the production process.
Helium is produced commercially and is commonly used in superconducting magnets in nuclear magnetic resonance (NMR) systems. At normal atmospheric pressure, liquid helium boils at at temperature of 4.2 Kelvin or -452.11 degrees Fahrenheit. It is important to have helium transfills scheduled in a timely manner to prevent the magnet from warming up and quenching.
Helium's inert properties at arc temperatures make it an ideal gas for welding materials with high heat conductivity such as aluminum, stainless steel, copper and magnesium alloys. Helium is also used in heat treating processes such as gas quenching and in furnace atmospheres to produce parts with higher tolerance and improved quality.
