1. Basic Properties
Magnesium (symbol Mg, atomic number 12) is a silvery-white lightweight metal, the lightest structural metal in common industrial use.
- Ultra-low density: much lighter than aluminum, about two-thirds the weight of aluminum alloy.
- High specific strength: light weight paired with decent strength for weight-reduction projects.
- Good thermal conductivity and electromagnetic shielding performance.
- Excellent castability and machinability, ideal for die casting and CNC processing.
- Active chemical property: easily oxidizes and corrodes in humid or salty environments; must rely on surface treatments for protection.
- Low melting point, easy for casting molding.
2. Common Surface Treatments
- Micro-arc oxidation (MAO): dense ceramic film for corrosion and wear resistance
- Anodizing, passivation, painting, powder coating
3. Main Alloy Grades
AZ31, AZ91D, AM60 are the most popular magnesium alloys for industrial manufacturing.
4. Typical Applications
- 3C electronics: laptop frames, mobile phone housings, camera brackets
- Automotive lightweight parts: engine covers, steering components, gearbox housings
- Aerospace lightweight structural parts
- Sporting goods: bicycle frames, golf club heads
- Medical lightweight auxiliary parts
