Magnesium CNC Machining
Magnesium is increasingly popular for CNC machining becaust it is lightweight and highly machinable in terms of feed rates. Machined magnesium also produces excellent surface finishes due to shorter chips being produced during the machining process. WSF offers multiple Magnesium alloys: AZ31-TP, AZ61B, AZ91D and AZ31B. Each has slightly different properties, but AZ31B is the most commonly used in CNC machining.

| Features | Description |
|---|---|
| Lightweight | Its density is only approximately 1.74 g/cm³, about two-thirds that of aluminum and one-quarter that of steel. It is the lightest structural metal currently available. |
| Good strength/rigidity | Despite its lightness, it boasts high strength and an excellent strength-to-weight ratio. |
| Good heat dissipation | It has excellent thermal conductivity and heat dissipation, making it commonly used in electronic product housings, heat sinks, and other applications. |
| Good electromagnetic shielding | Compared to plastic housings, magnesium alloys effectively shield electromagnetic interference (EMI). |
| Good shock absorption | It has strong vibration absorption, making it suitable for components requiring shock and vibration reduction. |
| Susceptible to oxidation and corrosion | The surface is easily oxidized, so surface treatment (such as anodizing, micro-arc oxidation, nickel plating, and painting) is often required. |
| High flammability | Magnesium powder and shavings are easily flammable, posing a significant safety hazard during processing. |
