Magnesium vs Steel: What is the difference ?

Magnesium vs Steel

When it comes to metal alloys, there are several to choose from. Two of the most popular metals used in manufacturing and construction are magnesium and steel. Both materials have distinct advantages, but how do they compare when it comes to strength, durability, cost, and more? Let’s take a look.

Strength and Durability

Steel is significantly stronger than magnesium, with a tensile strength that is at least ten times greater. It is also more durable and resistant to wear and tear. As a result, steel is often the material of choice for heavy-duty applications such as machinery or large structures. Magnesium has its own unique properties, however; it is lighter than steel (about two-thirds the weight), making it ideal for use in lightweight applications such as sporting goods or consumer electronics.


In general, steel costs less than magnesium due to its abundance in nature and widespread use in industry. However, this does not necessarily mean that steel is always the cheaper option; depending on the size and quantity of the order, magnesium can be competitively priced with steel when large orders are placed.

Environmental Impact

steel production requires high temperatures, which can lead to significant emissions of carbon dioxide into the atmosphere, while magnesium’s production process tends to release fewer emissions overall as no heat is required during its production process. This makes magnesium an attractive option for companies looking for ways to reduce their environmental footprint.


When deciding between magnesium or steel for your next project or product design, you will need to consider your needs carefully before making a decision. If you need something that is strong and durable enough for heavy-duty use, such as machinery or structural support, then steel may be your best bet. Alternatively, if you are looking for something lightweight yet still strong enough for everyday use, then magnesium could be the right choice for you. Either way, both metals offer distinct advantages that should be considered carefully before making a final decision.
