Why Choose Magnesium for CNC Machining Projects?
Magnesium offers significant advantages over aluminum when weight matters. It’s 33% lighter while keeping similar strength. This makes a big difference in aerospace applications, where every gram saved means better fuel efficiency.
Performance Benefits
- Machining magnesium requires less power (55% less than aluminum)
- Dampens vibration 10x better than aluminum
- Conducts heat well for cooling electronics
- Naturally shields against electromagnetic interference
- Better cutting tool life due to easier cutting
Though raw magnesium costs more than aluminum, the numerous benefits often make the total project cost comparable or better.
What Industries Benefit from Magnesium CNC Parts?
The industries that benefit most from our CNC precision machining with magnesium are Luft- und Raumfahrt, Automobil, electronics, medizinisch, and sports.
Luft- und Raumfahrt
Aerospace companies use machined magnesium components to save weight in non-critical components. The FAA has approved specific alloys for aircraft interiors. Less weight means better fuel efficiency and more payload capacity.
Automobilindustrie
Car makers use magnesium parts for steering wheels, dashboard frames, and transmission cases. According to the International Magnesium Association, the average car contains 10–12 pounds of magnesium, with racing and luxury vehicles using much more.
Elektronik
Consumer electronics benefit from magnesium’s lightweight strength. It’s relatively easy to machine into laptop bodies, camera frames, and mobile devices where weight matters, but durability can’t be compromised.
Medizinische
Medical device manufacturers use special alloys for implants that safely dissolve in the body over time. These controlled-degradation properties make magnesium unique for orthopedic applications.
Sports Equipment
High-end bikes, racing wheels, and performance equipment use magnesium machined parts to reduce weight while maintaining strength, giving athletes a competitive edge.

Magnesium CNC Machining FAQs
Magnesium presents unique challenges because it’s highly flammable in fine chip or dust form. It can ignite at around 473 °C (883 °F), much lower than aluminum or steel. This requires special safety systems, non-water coolants, and proper chip management. Despite these challenges, magnesium machining provides faster production than most metals due to its lower cutting resistance.
Magnesium parts can receive several protective treatments. Anodizing (DOW17, HAE, or Tagnite) creates a protective oxide layer that improves corrosion resistance. Chemical conversion coatings like chromate treatments offer good protection with minimal size changes. For maximum protection, we offer polymer sealants, powder coating, and E-coating. Each option is selected based on your part’s operating environment.
We prevent corrosion through multiple approaches. We start by selecting the right alloy—AZ91D offers better natural corrosion resistance. During the CNC machining of magnesium, we use pure cutting fluids to prevent contamination. After machining, we apply protective surface treatments like anodizing or chromate conversion coatings. For harsh environments, we recommend additional protection like E-coating or polymer sealants, plus design features that avoid water traps and contact with different metals. Never use water to clean magnesium parts as it can cause corrosion and potential fire safety issues.
