When to choose which
Choose Aluminum when…
- Thermal conductivity matters (heatsinks, enclosures).
- Higher stiffness / strength at similar wall thickness is needed.
- Corrosion resistance and mature recycling stream are priorities.
Choose Magnesium when…
- Minimum mass is critical (≈35% lighter than aluminum).
- Vibration damping and EMI shielding are beneficial.
- Thin-wall, complex lightweight housings are required.
