摘要：

The fifth critical raw materials (CRMs) list published by the European Commission (EC) in 2023 poses new restrictions to the usage of lightweight materials in the transportation industry. As per the publication, aluminium (one of the most widely used lightweight metals in the aerospace and automotive industry) has been declared as CRM and an increased criticality trend in its major alloying elements e.g. silicon and magnesium has been observed. Therefore, a novel approach is required to implement the criticality concept in developing new aluminium alloys and their processing for different components in the automotive industry. The present study aims to describe the strategy required to reduce the usage of CRMs in aluminium alloys along with enhanced high-pressure die casting (HPDC) processibility. By integrating criticality and castability assessment, a contribution to the development of sustainable and high-strength aluminium alloys to meet the demands of modern manufacturing while addressing the global resource challenges is presented. This study will also support the implementation of the CRMs concept in materials research and development.
