A Xiaomi Auto 2200MPa Szuper-Erős Acélja Nagy Metallurgiai Ipari Díjat Nyert

Greetings Xiaomi Fam 🫂💜🤝

Xiaomi Auto has announced that its 2200MPa super-strong automotive steel has won First Prize in the Metallurgical Science and Technology Award, jointly established by the China Iron and Steel Association and the Chinese Society for Metals.

Beyond the award itself, Xiaomi says the technology has already entered mass production and is being applied in the Xiaomi YU7, the new-generation Xiaomi SU7, and the Xiaomi SkyNomad. The achievement highlights Xiaomi Auto’s continued work on advanced materials for vehicle engineering and manufacturing.

The 2200MPa figure refers to the material’s tensile strength, measured in megapascals (MPa). In simple terms, tensile strength indicates how much pulling stress a material can withstand before breaking.

High-strength steel can help automotive engineers develop structural components that withstand substantial loads while managing the space and weight available in a vehicle. However, a material’s real-world performance also depends on its design, thickness, forming process and how it is integrated into the vehicle structure.

An Automotive Steel Series From 1000MPa To 2200MPa

According to Xiaomi Auto, the award-winning project is titled “Development and Application of 1000–2200MPa Series High-Performance Thin Aluminum-Silicon Coated Hot-Stamped Steel for Automobiles.”

The project covers a series of high-strength steels rather than a single material grade. Xiaomi says the 1000MPa, 1500MPa, 2000MPa and 2200MPa grades are all in mass production and application in its automotive programme.

The steel uses an aluminium-silicon coating and a hot-stamping manufacturing process. These technologies are intended to support the production of high-strength automotive components, with the coating and forming process playing important roles in manufacturing and material performance.

Collaboration Between Industry And Research

Xiaomi Auto attributes the achievement to collaboration between industry and academia, involving companies including Yucaitang and Northeastern University.

The project underwent a selection process before receiving First Prize in the Metallurgical Science and Technology Award. According to Xiaomi, the award recognises significant technological innovation in metallurgy, together with substantial economic and social benefits.

One of the most important details is that the project is not simply a research concept awaiting commercial use. Xiaomi says the resulting steel technologies have already reached mass production and are being applied across the Xiaomi YU7, the new-generation Xiaomi SU7 and the Xiaomi SkyNomad.

This demonstrates how materials research can move from development into vehicle manufacturing, where strength, manufacturability and structural design must work together. The award marks another milestone for Xiaomi Auto’s materials engineering efforts, with the company continuing to develop and apply advanced automotive technologies in its production vehicles.
