Versatile Magnesium Die Casting Solutions
We offer a variety of magnesium die casting methods to meet customer needs. We do both hot chamber and cold chamber magnesium die casting to produce small precision parts and large structural components. The multi-slide die-casting allows us to produce complicated shapes with the highest degree of accuracy, and the conventional die-casting realizes cost-effective production for ordinary designs. For whichever application, we propose the appropriate process to achieve lightweight, high-strength magnesium parts.
Multiple Magnesium Alloys for Your Projects
We offer magnesium die casting with different alloys to match your needs. AM60B provides high impact strength and good ductility, making it suitable for automotive safety parts. AZ91D is the most widely used magnesium alloy, known for its balance of strength, corrosion resistance, and cost efficiency. MgCarbonit 90 gives extra stability and unique performance for advanced applications. By choosing the right alloy, we help you achieve lightweight, strong, and reliable parts for your industry.
Magnesium die casting cuts part weight by roughly one-third versus aluminum while maintaining high strength and stiffness at the part level. Its superior stiffness-to-weight ratio and natural vibration damping help you meet NVH and durability targets, and its impact resilience protects edges, bosses, and clips.
Process-wise, magnesium fills thin walls and deep ribs at lower temperatures, enabling part consolidation, tighter tolerances, shorter cycle times, and reduced energy use. It also machines quickly, provides inherent EMI shielding for electronics, and accepts robust finishes (conversion coating, paint, or plating) for long-term corrosion protection.
Yes. Magnesium alloys have excellent toughness and can absorb energy under impact. This makes them resistant to dents and helps improve product durability, especially in structural and safety parts.
Magnesium is more prone to corrosion than aluminum, so durable surface protection (coating, plating, or powder coating) is usually required. Parts often need secondary work — CNC finishing, deburring, or coatings — to meet tight tolerances and appearance targets. Also consider porosity and melt-handling defects (controlled by proper melting, venting, and tooling), plus generally higher raw-material and handling costs. Discuss these trade-offs with us early to optimize design, finishing, and total cost of ownership.
Yes. Good magnesium die-casting starts with uniform, as-thin-as-practical wall sections, modest draft angles for reliable ejection. Involve our engineering team early so we can optimize part geometry and tooling to lower weight, improve strength, and cut total production cost.
Magnesium Die Casting vs Aluminum Die Casting
Choosing the right alloy is not a simple “light vs. strong” decision. It affects weight, feel, durability, cost, and the way your part is made. We produce both magnesium and aluminum die castings and help you match the material to the job.
Why magnesium works
Magnesium parts are about one-third lighter than aluminum. The material has high stiffness-to-weight and natural vibration damping, so housings feel solid and quiet in use. In hot-chamber die casting, magnesium fills thin walls quickly, which supports clean details and short cycle times. These traits make sense for handheld electronics, interior auto parts, drones, and any assembly where every gram matters.
Where aluminum still leads
Aluminum stands up better outdoors and in salty or wet environments. It also handles higher service temperatures. If your part lives under the hood, near heat sources, or faces long salt-spray exposure, aluminum is usually the safer pick. It is the common choice for structural brackets, heat-dissipating housings, and general industrial components that see rough conditions.
