1. Manufacture of lightweight alloys: Magnesium alloys are an important lightweight material, often used in aviation, automobiles and bicycles. Magnesium alloys have good mechanical properties and corrosion resistance, and are lighter than steel and aluminum alloys.
2. Manufacture of rocket fuel: Magnesium, as one of the main components of rocket fuel, can produce a high-energy explosive reaction after being mixed with an oxidant.
3. Making pyrotechnics: Magnesium powder can be used to make pyrotechnics, because it can burn to produce white light, thus providing special effects for pyrotechnic performances. Manufacture of anti-corrosion coatings: Since magnesium can effectively prevent metal oxidation and corrosion, magnesium is often used in the manufacture of anti-corrosion coatings.
4. Manufacture of optical instruments: Magnesium is a transparent metal that is often used in the manufacture of optical instruments and photographic equipment, such as cameras, microscopes and telescopes.
5. Making batteries: Magnesium can also be used to make batteries, such as magnesium-aluminum batteries and magnesium-air batteries. These batteries have high energy density and long life.
6. Medical application: Magnesium is one of the important minerals necessary for the human body, so it also plays an important role in medical application. For example, magnesium can be used to treat conditions such as fatigue syndrome, high blood pressure, diabetes and asthma.
In short, magnesium has a wide range of uses, from aviation, automobile, bicycle and other manufacturing industries to medical applications, it plays an important role.
