Applications of helium in aerospace:

Superpure helium such as 6N helium is used as pressurized gas to transport liquid propellant such as liquid hydrogen and oxygen in rockets and spacecraft. Throughout the aerospace and aircraft manufacturing process from manufacturing to flight, space flight operations use helium to purify hydrogen systems, which are used as pressurizers by ground and flight fluid systems. In addition, helium is used as a lift source for weather and other observation balloons.

Transport and transport equipment for helium use:

Helium is the lowest boiling point gas and has excellent thermal conductivity, so it is widely used in the test of radiator heat exchanger, air conditioning module, fuel tank, torque converter and other important automobile parts to ensure its quality specification. In addition, helium gas can be used in conjunction with argon and is increasingly used in airbag charging operations.

USES of helium for entertainment and decoration:

Helium voice performance you've all heard of, after inhaling helium, because helium propagation speed of sound to about three times that of air, inhaled with helium gas, the frequency of sound will become higher and can imitate the soprano singer, also can call a person to speak shrill thin air, like old cartoon character. But helium is also a choking gas, without professional guidance, it is easy to inhale too much helium to cause suffocation, the risk of death! There has also been a lot of news recently about helium voice changes, such as Morgan Freeman's three-second makeover with a Donald Duck accent. Take, for example, balotelli's recent helium-filled rant about Liverpool.

Medical and health USES of helium:

Helium-neon lasers can be used for surgery, to treat amblyopia, and to activate blood vessels for health care. The gas media in helium-neon lasers are neon and highly pure helium. In addition, due to its low temperature superconductivity, helium is an ideal frozen gas for magnetic resonance and NUCLEAR MAGNETIC resonance superconducting magnets. Helium can achieve a cryogenic temperature of -451 degrees Fahrenheit, effectively obtaining high-resolution images of internal organs and tissues.

Electronic research on USES of helium:

Helium plays an important role in semiconductor, liquid crystal panel and fiber optic line manufacturing, enabling rapid cooling of components to increase productivity, and controlling heat transfer rate to improve production efficiency and reduce defects. In addition, helium can also be used as a carrier gas in the production process, and high purity helium can be used as a carrier gas for instruments such as gas chromatographs/GMS.

Welding and metalworking of helium:

High purity helium gas is used with high purity argon as a protective gas for special welding. The inertia of helium at arc temperature makes it an ideal gas for welding of high thermal conductivity materials such as aluminum, stainless steel, copper and magnesium alloy. It can also be used as quenching gas and furnace gas in heat treatment process to improve the tolerance and quality of parts.

Diving gas for helium use:

Oxygen and helium must be filled in oxygen tanks for deep water diving. Helium, which replaces nitrogen in deep-sea diving, is less prone to deep-sea paralysis.
