Do magnesium alloys have any drawbacks?

Although magnesium alloys have many advantages and application values, they also have the following drawbacks:

1. Flammability: Magnesium alloy is prone to react with oxygen in the air, causing a thermal reaction that produces flames and sparks. Therefore, it is necessary to pay attention to safety issues such as fire when using magnesium alloys.

2. Poor antioxidant capacity: The surface of magnesium alloy is easily affected by gas oxidation and corrosion, so surface treatment is needed to improve its antioxidant performance.

3. High manufacturing cost: Magnesium alloys have a high melting point and require high temperatures during manufacturing, resulting in high manufacturing costs.

4. Poor processing performance: Magnesium alloys have poor processing performance and are difficult to process and form, requiring the use of special processing techniques.

5. Low toughness: Magnesium alloys are prone to cracking and are prone to fracture under stress conditions such as impact or torsion.

6. Easy to damage: The surface of magnesium alloys is susceptible to mechanical or chemical damage, so protection and maintenance are necessary.

In summary, although magnesium alloys have many advantages, there are also some drawbacks that need to be noted, which are also requirements for material selection and use.
