2. Helium is used as a shielding gas during smelting and welding, which is important in shipbuilding and the manufacture of aircraft, spacecraft, rockets and weapons.
3. Helium has good permeability, which is used for cooling nuclear reactors, leakage detection of some pipelines and electronic and electrical devices of rockets and nuclear reactors.
4. Helium is a gas with ideal gas properties and is an ideal gas for vapor pressure thermometers at very low temperatures.
5. Helium has low mass density and weight density, and is not flammable, which can be used to fill bulbs, neon tubes, and is also ideal for balloons and airships.
6. Liquid helium can obtain a low temperature close to the temperature (-273 °C) and is used to manufacture superconducting equipment.
7. A kind of helium inert gas, the solubility in the blood is lower than nitrogen, so its anesthesia is lower than nitrogen, so helium is often mixed with oxygen as a diver's breathing gas.
