Advances in Lightweight Alloy Die Castings Drive the Application of Structural Components in New Energy Vehicles

Application of Aluminum Alloy Die Castings:

Aluminum alloy die castings are primarily used in automotive, machinery, electronics, communications, instrumentation, household appliances, and other industries. Among them, automotive components account for the largest proportion, approximately 70%. The automotive industry is a pillar industry for the die casting sector, as the production of die castings is significantly correlated with automobile production. In recent years, the trends in die casting production and automobile production have shown a significant positive correlation. Due to the continuous increase in automobile production, the production of die castings has also been on the rise, with an annual growth rate exceeding 10% for more than a decade. the increase in die casting production consists of two parts: one part is driven by the increase in automobile production, while the other part is driven by the increased usage of die castings per vehicle. The increased usage of die castings per vehicle is mainly attributed to the development of new energy vehicles in recent years, which has accelerated the application of structural components. This trend was particularly evident in 2020, when die casting production increased against the backdrop of declining automobile sales. One of the main reasons for this increase was the significant contribution of structural component usage. The upward trend is expected to be even more pronounced in 2021, indicating that new energy vehicles have a significant driving force in the application of structural components.
