The potential of the automobile manufacturing industry - where is the incremental large magnesium alloy parts for automobiles?

In the vast starry sky of the manufacturing industry, magnesium alloys are gradually emerging with their unique charm, especially in the manufacturing field of large parts. It not only shows its excellent performance, but also indicates the huge possibility of future market growth. At present, there are nearly 70 original magnesium smelters in China, but there are only about 20 companies with alloy production capabilities, and there are very few manufacturers that are truly involved in the production of automobile magnesium alloy die-casting parts. This situation reflects the challenges faced by the magnesium alloy industry in the process of development, but also indicates its huge market potential.
It is worth mentioning that although most companies do not yet have the real magnesium alloy product design and development capabilities and are still at the stage of processing according to drawings, some pioneering companies in China, such as Magnesium Redding, have achieved remarkable results in the application and promotion of magnesium alloys. They have not only successfully developed a number of large magnesium alloy automobile parts, but also have been widely used in actual production, making positive contributions to the progress of the industry.

As an enterprise with remarkable achievements in the field of large magnesium alloy application parts, Magnesium Redding has successfully developed a number of large magnesium alloy automobile parts and has been widely used in actual production. The magnesium alloy structural parts it developed not only significantly reduced the weight of the vehicle body, improved fuel economy, but also enhanced the handling and safety of the vehicle. These successful cases not only demonstrated the advantages of magnesium alloys in the manufacture of large components, but also provided valuable experience and reference for other domestic companies.

With the rapid increase in the penetration rate of new energy vehicles, mileage anxiety has become the core concern of consumers, further increasing the urgent need for lightweight vehicles, and the application of magnesium-aluminum alloys has also been used as an important means of lightweighting by new energy vehicles.

01 Instrument panel crossbeam frame

The company has been engaged in the design and manufacturing of instrument panel crossbeam frames (CCBs) since 1994, and has successfully provided high-quality CCB products to more than 20 automotive original equipment manufacturers (OEMs) around the world. With the continuous evolution of design strategies and performance requirements, the weight of castings has also shown a trend of diversification, which in turn affects the selection of die-casting machine tonnage. Due to its excellent integration and connection performance, die-castings effectively reduce the dependence of instrument panel assembly on other structures, thereby helping OEMs achieve lightweight CCBs and save costs. In addition, the magnesium alloy tailgate inner panels produced by Magnesium Redding have been mass-produced in North America and are widely used in vehicles of multiple OEM brands around the world. The average weight of the dashboard crossbeam frame is 5 kg.

02 Door inner panel

The liftgate inner panel of the 2010 Lincoln MKT is 40% lighter than the traditional stamped steel door inner panel, and the mold investment is also reduced by 57%. This liftgate inner panel is assembled from three structural components, of which two aluminum plates are used as outer panels. In addition, it also integrates the originally scattered six different components into a structural casting, which not only optimizes the production process, but also improves the structural strength of the whole vehicle. The size of the casting is 1380mm wide x 1315mm high, which effectively improves the headroom of the passengers. At the same time, the surface of the casting meets the A-level standard, ensuring the appearance quality of the vehicle. After preliminary measurement, the average weight of the inner door panel is 6.5 kg.

03 Electric drive housing

Magnesium alloy armature housings have made significant progress in the lightweighting of new energy vehicles. SAIC Zhiji Automobile took the lead in adopting it, and the early market witnessed the widespread application of magnesium alloy gearbox housings. This series of mass production proves the core position of magnesium alloy materials in the new energy vehicle industry. Its smaller weight and higher strength show significant advantages over traditional aluminum alloy shells. This milestone mass production application has opened up new application scenarios for magnesium alloys. The average weight of the electric drive shell is about 15 kg.

04 Seat frame

Wanfeng Magnesium Redding seat frame is made of advanced magnesium alloy materials and inherits many advantages of magnesium alloy. However, compared with other magnesium alloy seat frames, Wanfeng Magnesium Redding seat frame has been more finely polished and optimized in design and process. This allows it to pay more attention to comfort and ergonomic design while ensuring strength and toughness, providing passengers with a seat experience that fits the human body curve better. The average weight of the front and rear seat frames in a car is about 8 kg.

05 Display back panel and bracket

The magnesium alloy display back panel and bracket not only have sufficient supporting strength, but also have a lightweight design to reduce the volume and weight, making the display device lighter and easier to carry. It is estimated that the average weight of the display back panel and bracket is about 3.5 kg.

According to the current market information, we predict that by 2025, the use of large magnesium alloy parts for automobiles will reach at least 38 kg per vehicle, including the weight after preliminary measurement (CCB + electric drive housing + door inner panel + display back panel and bracket + seat frame) mentioned above. 14000000×38kg=532000000kg=532,000 tons. 532000000×55=29260000000=29.26 billion.
Therefore, the market demand in 2025 is predicted to be: 29260000000-3200000000= 26.06 billion, and the gap is 26.06 billion.

It can be seen that the market for large magnesium alloy parts for automobiles has broad incremental prospects and huge market gaps, which provides a rare development opportunity for the layout of magnesium alloy die-casting plants.

Considering that there are thousands of companies in China with high-pressure die-casting mold manufacturing capabilities, and most of these companies are located in Zhejiang Province, they have potential transformation capabilities. It can be foreseen that once the application of magnesium alloys is more widely promoted and applied, these companies will become an important force to promote the rapid growth of magnesium alloy production capacity. With the continuous expansion of the application of magnesium alloys in various fields, such as automobiles, electronics, aerospace, etc., the demand for magnesium alloys will continue to grow. This will prompt these companies with transformation capabilities to actively invest in the production of magnesium alloys and further increase the production capacity and output of magnesium alloys.

At the same time, since raw magnesium is needed as a raw material in the production process of magnesium alloys, as the production capacity of magnesium alloys increases, the demand for raw magnesium will also increase accordingly. This will drive raw magnesium production companies to expand production scale and improve production efficiency to meet the market demand for raw magnesium.
