With the continuous progress of technology and the increasing complexity of application requirements, material databases play an important role in engineering applications such as product design, component selection, structural analysis, strength analysis, and failure analysis. However, commercial material databases cannot be combined with engineering applications, and there are risks such as high cost of use and data leakage. In response to this situation, a materials database for engineering applications is constructed, which not only has rich data resources, but also provides convenient data query and visualization tools. Practical application cases show that the database can significantly improve the efficiency of engineers, reduce the cost of research and development, and promote the innovation and development of engineering technology.
