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.
