Problems solved by technology

At the same time, with the continuous improvement of equipment lightweight requirements, aluminum alloys have gradually become a research hotspot for 3D printing materials, but traditional high-strength aluminum alloys will crack due to factors such as segregation and intermetallic compounds when they are formed by 3D printing methods. Therefore, it is urgent to develop high-strength aluminum alloy powder suitable for 3D printing
[0003] At present, when the cast aluminum alloys conventionally used for 3D printing are used at temperatures exceeding 100°C, their mechanical properties will drop rapidly, causing parts to fail during use. Long-term service at higher temperatures
