From the perspective of the entire automobile structure, in addition to the large number of precision die-casting parts used in the automobile engine, gearbox, transmission system, steering system, and electronic control system, aluminum alloy die-casting parts are also used for large components such as the body frame. As people pay more and more attention to automobile energy conservation and environmental protection, the automobile industry has shown a trend of replacing steel and iron with aluminum in the past 30 years, and the global automobile aluminum alloy die casting market has grown rapidly. According to the forecast of the North American Die Casting Association (NADCA), the global automotive aluminum alloy die casting sales will reach 16.352 million tons in 2025, an increase of 83.19% over 2012.
Therefore, die castings mainly made of aluminum alloy die castings will be more used in new energy vehicles. Others include zinc alloy, magnesium alloy die casting, and stamping parts will also occupy a small part.
