Under the general trend of automobile lightweight, the CAGR of magnesium alloy market demand reached 13. 2%. The vast majority of automotive magnesium alloy parts are die casting parts, which are mainly used in housings and brackets.
New York, Nov. 08, 2021 (GLOBE NEWSWIRE) -- Reportlinker.com announces the release of the report "China Automotive Magnesium Alloy Die Casting Industry Report, 2021" - https://www.reportlinker.com/p06179282/?utm_source=GNW
Magnesium alloy is a good substitute for steel and aluminum alloy, and can reduce the product weight by 25%-75%. However, the current application ratio of magnesium alloy in automobiles is much lower than that of aluminum alloy.
Magnesium alloy facilitates lightweight vehicles
Given energy saving, environmental protection and performance, lightweight vehicles have become one of the important directions for the development of the global automotive industry. In 2020, China released Energy-saving and New Energy Vehicle Technology Roadmap 2.0, putting forward lightweight requirements for all types of vehicles. In addition, major automakers have proposed goals of promoting the development of lightweight vehicles.
At present, lightweight vehicle technology is mainly divided into three types: lightweight material technology, lightweight advanced process technology, and lightweight structure optimization technology. Lightweight materials are the key to lightweight vehicles.
Magnesium alloy features low density, high strength, good heat dissipation, strong vibration resistance, noise reduction, excellent die casting performance, and outstanding cutting performance, as an ideal lightweight material. Under the trend of lightweight vehicles, the market demand for magnesium alloy will grow rapidly.
In 2015, a single car in China only used about 1.5kg of magnesium, which was far lower than the level in Europe, America, Japan and other regions. However, with the rapid development of new energy vehicles and the acceleration of the lightweight vehicle process, the amount of magnesium used in a single vehicle in China has grown rapidly, and it is estimated to reach 15kg in 2020.
As per Energy-saving and New Energy Vehicle Technology Roadmap 2.0, a single car in China will use 45kg of magnesium alloy, which will account for 4% of the total vehicle weight by 2030 when the Chinese automobile market will demand 1.31 million tons of magnesium alloy die casting parts with a CAGR of 13.2% in 2020-2030.
Magnesium alloy boosts lightweight new energy vehicles
For every 10% reduction in the weight of new energy vehicles, the average cruising range can increase by 5%-8%. Therefore, the demand for lightweight new energy vehicles is urgent. The density of magnesium alloy is 2/3 that of aluminum and 1/4 that of steel, so it is much lighter than the latter two, which means that magnesium alloy is the best choice for lightweight new energy vehicles.
New energy vehicle battery packs account for more than 20% of the vehicle weight, thus lightweight new energy vehicles partly hinge on lightweight battery packs.
Lightweight battery packs can make outer casings, bottom trays, and inner end/side panels lighter. For example, Tesla MODEL S mainly uses aluminum alloy for the battery pack shell which weighs up to 125 kg; if it uses magnesium alloy, the weight will be reduced by about 60 kg or nearly 50%.
At present, Wanfeng Meridian, Qianhe Magnesium, RSM Group, Eontec, Ka Shui Group, etc. have made layout in the field of magnesium alloy casting for battery pack shells of new energy vehicles.
As the world’s leading supplier of new energy vehicle batteries, CATL has also deployed magnesium alloy die casting for battery packs. In November 2020, CATL, Sanxiang Advanced Materials, Vansun Group, and Zhuhai Hengqin Yinmei Technology jointly established Ningde Wenda Magnesium-Aluminum Technology Co., Ltd. to build a magnesium-aluminum alloy project with a total investment of RMB800 million. The products include die casting structural parts for battery casings.
Wanfeng Auto Wheel leads the market amid low market concentration
At present, the global automotive magnesium alloy die casting market is highly fragmented with low market concentration The relatively large-scale companies mainly include Georg Fisher, DGS, STIHL, Wanfeng Meridian, SUNDARAM CLAYTON, Gibbs, PACE, etc.
In the short history of China’s automotive magnesium alloy die casting market, there are only a few companies of a certain size, mainly including Wanfeng Auto Wheel, RSM Group, Sinyuan ZM, Eontec, Ka Shui Group, etc.
Wanfeng Auto Wheel has become a leader in the automotive magnesium alloy die casting market in China and even in the world through the acquisition of Wanfeng Meridian which was granted the Automotive Casting Excellence Award by The International Magnesium Association (IMA) for two consecutive years. Wanfeng Meridian serves not only Tesla, NIO and other new energy vehicle companies, but also traditional automakers such as Porsche, Audi, Mercedes-Benz, BMW and Volvo.
Enormous market potentials prompt companies to expand production
In view of enormous market potentials, domestic companies have invested in building or expanding automotive magnesium alloy die casting bases to meet the growing market demand. In the future, the competition in the industry will become more intense, and the automotive magnesium alloy die casting market will mature.
