Uses of Magnesium Alloys

21 February 2020

Nowadays, many manufacturing companies from different industries have been using magnesium alloys on their parts and products since they are lightweight and durable. Magnesium alloys are composed of magnesium and other metal elements such as manganese, aluminium, zinc, silicon, copper, and other metal elements.

Among the prominent qualities of magnesium alloys include low specific gravity, high strength-to-weight-ratio, exceptional machinability, and low production cost. Materials out of magnesium alloys also enjoy stiffness, superior impact resistance, high vibration absorption, and highly effective thermal management.

The mentioned properties of magnesium alloys make them suitable for different uses and applications across numerous industries around the world.


The high strength and low-density properties of magnesium alloys make them suitable for automotive applications. According to some data, the overall performance of vehicles is significantly improved whenever manufacturers use magnesium alloys on their assembly of vehicles. This material also reduces the overall weight of the vehicles. Today, magnesium alloys are used in gearboxes, steering columns and wheels, seat frames, fuel tank covers, front consoles, and hoods.


Just like vehicles, the aerospace industry has also embraced the use of magnesium alloys on their assembly. Almost all air and spacecraft utilise the use of magnesium alloys since they have to lower their overall weight. Magnesium alloys are used in creating thrust reversers for some plane models, engines, and transmission casings of aircraft and helicopters.

Spacecraft and missiles also use magnesium alloys since these materials can withstand extreme conditions such as dramatic elevated temperature changes, exposure to ozone, and impact of high energy particles and matter.


Going back to mainstream products, magnesium alloys are now used in different forms of appliances, devices, and equipment. A lot of devices are now being created to be as compact as possible. So, keeping these devices lightweight would be a priority for manufacturers. Magnesium alloys can also regulate heat transfer and dissipation very well. They can also shield any electromagnetic and radio frequency interference. With these properties, products like cameras, phones, laptops, tablets, and other media devices now use magnesium alloys as part of their assembly.

Aside from these devices, handheld work tools and household appliances have also magnesium alloys on their components. Some mainstream products that are now comprised of these alloys include chainsaws, hand shears, hand drills, nail guns, vacuums, and many more.


Magnesium alloys have been heavily used in the medicinal industry since they possess most qualities of a natural bone. They can serve as the orthopaedic biomaterial that can be developed for implants and other similar applications. The density of magnesium alloys can match the density of natural bones. Even the fracture toughness, elastic modulus, and compressive yield strength of both the magnesium alloys and natural bones are close to each other.

Magnesium alloys are essential to vital industries since they have a lot of great properties. If you want to know the process of creating products out of magnesium alloys, then you can visit us at CH Tooling & Engineering.
