2. Advantages of this AlMgErZr Powder
This powder offers a superior strength-to-weight ratio, making it ideal for lightweight structural components. The addition of Erbium (Er) and Zirconium (Zr) provides excellent grain refinement and precipitation strengthening, resulting in high tensile and yield strengths (≥520 MPa and ≥480 MPa respectively) while maintaining good ductility (≥12% elongation). Its high sphericity (≥0.9) ensures excellent flowability and packing density, which are critical for consistent powder spreading in additive manufacturing.
3. Application in Additive Manufacturing
AlMgErZr aluminum alloy powder is specifically optimized for Selective Laser Melting (SLM) processes. Its tailored particle size distribution (centered around 30-45 µm) and high sphericity allow for the creation of dense, defect-free layers during printing. This results in printed parts with exceptional mechanical integrity and surface finish, meeting the rigorous standards required for functional end-use parts in the aerospace, rail, and automotive sectors.
4. What is: AlMgErZr Aluminum Alloy Powder
AlMgErZr Aluminum Alloy Powder is a high-performance, high-strength, and tough aluminum alloy powder specifically designed for metal additive manufacturing (such as SLM/DMLS 3D printing). By introducing rare-earth elements Erbium (Er) and Zirconium (Zr) into the traditional Aluminum-Magnesium (Al-Mg) alloy system, it achieves exceptional strength and good ductility, making it an ideal structural material for aerospace, automotive lightweighting, and other advanced fields.

Core Characteristics
Ultra-high Strength and Good Toughness
Through rare-earth element strengthening, parts printed and heat-treated with this powder exhibit exceptional mechanical properties:
- Tensile Strength: ≥ 520 MPa
- Yield Strength: ≥ 500 MPa
- Elongation: ≥ 12%
Excellent Microstructure and Printability
- Grain Refinement: During the printing process, Er and Zr elements can form primary phases such as Al₃Zr.
- High Density: Achieves a forming density of over 99.9%, with a dense internal structure free of cracks.
- Low Spatter: The optimized composition ratio significantly reduces smoke, dust, and spatter during the printing process, providing a wider processing window.
Strengthening Mechanism
The superior performance of the AlMgErZr alloy stems from the synergistic effect of multiple strengthening mechanisms:
- Solid Solution Strengthening: Elements like Mg and Zr dissolve in the aluminum matrix, increasing the matrix strength.
- Grain Refinement Strengthening: The Al₃Er phase can effectively refine the alloy grains, significantly boosting both the strength and toughness of the material.
Major Application Fields
Due to its combination of “lightweight” and “ultra-high strength” characteristics, AlMgErZr powder is primarily used in scenarios with strict demands for service reliability:
- Aerospace: Large-scale lightweight load-bearing structural parts, drone frames, satellite brackets.
- Automotive Industry: High-performance chassis components, lightweight body structures, new energy vehicle battery pack frames.
- Rail Transit: High-strength, lightweight car body structural components.
