Many military helicopters such as these Sikorsky Black Hawk helicopters contain gearbox casings made of magnesium because of its low density, which makes it less likely to catch fire. In the case of the MH17 crash, the aircraft was shot down by a surface-to-air missile fired by pro-Russian separatists in eastern Ukraine.

Why magnesium is used in aircraft?
As a result of these properties, these alloys can reduce the weight of aircraft, which in turn reduces fuel consumption and CO2 emissions. Lighter magnesium alloys are more susceptible to wear and damage than their heavier counterparts.
In addition, magnesium is an excellent conductor of heat and electricity, making it an ideal material for high-temperature applications such as jet engines. It is also a good insulator, meaning that it can be used in a wide range of applications, including batteries and solar cells.
Is magnesium used in aircraft construction?
Critical gearbox parts for the Sea King helicopter and aircraft wheels are two examples of Magnesium alloy forgings being used. Forged magnesium parts are used on the Boeing 787 Dreamliner and the Airbus A320neo. In addition to its use in aircraft, magnesium is used for a wide range of industrial and consumer products.
It is the most abundant metal in the Earth’s crust, and it is found in all of the world’s oceans. States alone, more than 1.5 million metric tons of magnesium are produced each year.
What does the military use magnesium for?
Our magnesium powders are used in anti-missile flares to keep air force personnel out of harms way. Military personnel are trained in the proper use of the weapons with the help of our magnesium powders.
Why is magnesium not used in aircraft?
In the past, magnesium alloys were forbidden for use in airplanes due to flammability concerns, but in recent years that has begun to change. In the past magnesium was not allowed to be used in aircraft because of the risk of fire. However, recent studies have shown that magnesium is not a fire hazard.
In addition, magnesium has been shown to have a number of health benefits. ;
- It is a good source of magnesium
- Potassium
- Calcium
- Iron
- Copper
- Manganese
- Zinc
- Selenium
- Vitamin b6
- Folate
- Thiamine
- Riboflavin
- Niacin
- Pantothenic acid
In fact, it is the only nutrient found in nature that can be considered a “superfood” and is often used as a dietary supplement.
Why is magnesium used in jet engines?
Reducing weight in fuselage structures, interior appliances, avionics, and other critical components, as well as reducing the weight of the aircraft, are some of the benefits of high-performing magnesium alloys. In addition, magnesium is an excellent conductor of heat and can be used as an insulator. It is also a good thermal conductor, which means that it can dissipate heat more efficiently than other metals, such as aluminum, steel, or copper.
Is magnesium better than aluminum?
Magnesium is 75% lighter than steel, 50% lighter than titanium, and 33% lighter than aluminum. It is capable of withstanding 10x more than it’s own weight, which is the highest known capacity of any structural metal.
It is also extremely resistant to corrosion, which is why it has been used for thousands of years in the construction of ships, bridges, skyscrapers and other structures.
In fact, it was the first metal to be used as a structural component in a building, as the Romans used it to build the Colosseum in Rome, the Eiffel Tower in Paris and the Empire State Building in New York.
Is magnesium more expensive than aluminum?
Despite its advantages, magnesium is not as stable as aluminum. Under stress, it is easier to bend. It is more difficult to recycle because it is more expensive than aluminum. “Magnesium is a good material, but it doesn’t hold up to the rigors of recycling,” .
