Magnesium Alloy Powder in Robotics Manufacturing: Next-Generation High-Performance Materials
1. Magnesium Alloys: The Core of Lightweight Robotics
Magnesium alloy powder is becoming an essential metal for robotics manufacturing, thanks to its lightweight, high strength, and superior thermal conductivity.
In industrial and humanoid robots, magnesium alloys are widely used in joint housings, transmission systems, skeleton structures, and sensor mounts.
By applying atomized spherical magnesium powder, these parts achieve 30–40% weight reduction without compromising strength, significantly improving energy efficiency and motion response.
2. Semi-Solid Injection Molding: A Breakthrough in Structural Lightweighting
Semi-solid injection molding is one of the key applications of magnesium alloy powder. This process controls the slurry forming temperature at around 580°C, achieving:
⚙️ Wall thickness below 0.6 mm for high-precision components
💡 Porosity lower than 0.1%, resulting in improved density
⚡ 30% lower energy consumption, supporting green manufacturing
Using Tangshan Weihao’s high-purity atomized magnesium powder, robotic joint housings and gearbox casings gain higher mechanical stability and heat dissipation efficiency.
3. 3D Printing: Integrating Complexity and Performance
In metal additive manufacturing, magnesium alloy powder is opening new design possibilities. Through Laser Powder Bed Fusion (LPBF), alloys such as AZ91D and WE43 enable:
🔩 Integrated manufacturing of complex topology structures, reducing weight by 20%
🔬 Low oxygen content and high sphericity, ensuring stable printing
✈️ Ideal for aerospace, robotics, and drone applications
With proprietary atomization technology, Tangshan Weihao achieves uniform particle size distribution, low oxygen level, high tap density, and batch consistency, providing an ideal powder for precision 3D printing.
4. Industry Trends: From Substitution to Performance Evolution
With the mass production of humanoid robots and the trend toward lightweight collaborative robots, magnesium alloys are shifting from being an alternative to aluminum to becoming a multifunctional structural material.
Future directions include:
Rare-earth strengthened Mg alloys – enhancing high-temperature strength and fatigue resistance
Mg-based composites – improving thermal conductivity and electromagnetic shielding
Surface engineering – micro-arc oxidation and electroless nickel plating for better corrosion resistance
Tangshan Weihao continues to advance magnesium alloy powder technology in both 3D printing and semi-solid forming, providing lighter, stronger, and smarter material solutions for the robotics industry.
