Introduction
Core changes in the standard revision
| Technical dimension | GB/T5154-2010 | GB/T5154-2022 | Impact of changes |
|---|---|---|---|
| Grade system | Including 7 grades such as Mg99.00 | Added 6 grades such as ZK61M/LZ91N | Expanded aerospace application scenarios |
| Dimensional deviation | Ordinary grade ±0.25mm(8-10mm) | Tightened to ±0.22mm | Improve precision machining adaptability |
| Unevenness requirements | ≤12mm(1000-1200mm width) | High precision grade≤10mm | Meet the needs of automotive covering parts |
Analysis of key performance indicators
Comparison of mechanical properties of typical grades
Implementation recommendations
- New material verification: For newly added magnesium-lithium alloys such as LA93M, it is recommended to first conduct a salt spray test to verify its corrosion resistance
- Dimension control: Strips with a thickness of ≤2mm should be monitored online using a laser thickness gauge
- Packaging improvement: Referring to clause 8.2.1, the amount of moisture-proof agent should be increased by 30% in humid areas
Technology evolution analysis
This standard introduces ZK61M-T5 state plates for the first time, and its 290MPa tensile strength marks a breakthrough in my country's rare earth magnesium alloy preparation technology. Compared with the US ASTM B90-20 standard, the strength indicators of products of the same specification are already the same, but there is still a gap in the field of ultra-thick plates above 70mm.
