Introduction
GB/T44151—2024 National Standard for Magnesium and Magnesium Alloy Powder for Additive Manufacturing in Depth
1. Background of Standard Formulation and Analysis of Technology Evolution
With the rapid development of Additive Manufacturing (AM) technology, magnesium and magnesium alloy powders have been widely used in aerospace, automotive, medical and other fields due to their lightweight, high strength and excellent biocompatibility. However, the technical requirements and quality control of magnesium powder for additive manufacturing in the existing standard system are still imperfect, and it is urgent to formulate a unified national standard to regulate the development of the industry.
This standard GB/T44151—2024 was issued by the State Administration for Market Regulation and the National Standardization Administration, aiming to fill the gap in the field of magnesium alloy powder for additive manufacturing in China, ensure the consistency of product quality and technical requirements, and provide technical support for related industries.
2. Comparative analysis of standard frameworks
| Standard dimensions | Product classification | Technical requirements | Test methods |
|---|---|---|---|
| Chemical composition | 6 grades: FMg9980, FAZ91D, etc. | Table 1 specifies the content range of each element in detail | GB/T13748, YS/T617.1, etc. |
| Particle size range | Two categories: Class I (15μm~53μm) and Class II (45μm~150μm) | Table 2 specifies the particle size composition and use | GB/T1480, GB/T19077 |
| Physical properties | Bulk density and fluidity requirements | Value ranges specified in Table 3 and Table 4 | GB/T1479.1, GB/T1482 |
3. Implementation suggestions and practical application cases
(1) Select appropriate powder grade and particle size
Select magnesium alloy powders of appropriate grade and particle size range according to the specific application scenario. For example, laser powder bed fusion process should use Class I powder (15μm~53μm), while electron beam powder bed fusion is suitable for Class II powder (45μm~150μm).
(2) Strictly control chemical composition
Ensure that the content of magnesium and alloy elements meets the standard requirements to avoid performance degradation due to excessive impurities. For example, the active magnesium content must be ≥98.5%, and other trace elements such as Fe and B should be strictly controlled within the allowable range.
(3) Pay attention to the powder preparation process
It is recommended to use gas atomization, centrifugal atomization or plasma spheroidization to ensure that the powder has good sphericity and fluidity. It is recommended to reduce the production of hollow powder through process optimization.
