Bottlenecks encountered in the use of Magnesium Die Casting Parts in the car industry

Dec. 30, 2019

Magnesium Die Casting Parts to have broad application prospects and extremely important economic value in the fields of automotive, electronics, electrical appliances, transportation, aerospace, aviation, defense and military. However, the electrode potential of magnesium alloys is very negative, and the oxide films of magnesium alloys are usually porous and porous, with high chemical and electrochemical activity, so their chemical stability is low and corrosion resistance is poor. In addition, magnesium alloys have low hardness and poor wear resistance. These defects also limit the widespread application of magnesium alloys to some extent. widely used. Therefore, how to effectively improve the wear resistance and corrosion resistance of magnesium alloys from the perspective of satisfying industrial applications has become a key technical problem to be solved urgently in the development and research of magnesium alloys.

Magnesium alloys have been used in the car industry for a long time. Now magnesium alloy die-casting parts have been used in cars. In Audi cars, transmission cases, chassis parts, hand brakes, steering brackets, pedal frames, beams, Ceiling structure, etc. On Mercedes-Benz models, B series steering gear housings, CL series door trims, transmission housings, SL series fuel tank covers, etc. have been used.

As a China Die Casting Parts Factory, share information with you. Magnesium alloy is currently the lightest structural metal in engineering use, together with outstanding damping and shock-absorbing functions, occupying a strategic advantage in the trend of lightweight in the car industry. The resources of primary magnesium are abundant, and the content of crustal engineering metals is second only to aluminum and iron, ranking third, and the content of seawater is second only to sodium, ranking second. In addition, China has abundant magnesium resources and is a large producer and exporter of magnesium.

Nowadays, the research and development of magnesium alloy car castings have increased collaboration with the world's leading manufacturers and research institutions. The proposal of the China-US-Canada World Collaboration Project is an important step to open up the use of magnesium alloy castings. Through the China-US-Canada MFERD collaboration project network channel, the three parties shared resource and effect data. The project will rely on U.S. and Canadian design and testing channels to break the magnesium alloy forming, connection and appearance protection skills, complete a number of tests such as collision resistance, NVH, fatigue durability, etc., and develop car god beams, beams, shock absorption towers, etc. Key components, reducing the front-end component, occupying the commanding height of lightweight technology of cars.

Many existing magnesium alloys in China lack originality. In the past, the use of magnesium alloys was more simply export of castings, which were mainly copied or produced according to drawings and samples provided by users, and there was a lack of originality in China. Although the prospects for the use of magnesium alloys are attractive, many uses of magnesium alloy castings in passenger cars still need time. At the time when the demand of the magnesium industry was sluggish and bottlenecks, demand looked more calmly at the prospects for the future use of magnesium alloys. It is not exaggerated by the development of use, nor is it lost by the sluggish use. First of all, we must fully understand the current difficulties and bottlenecks in the use of magnesium alloys in the field of cars, cooperate with users to deal with the use of magnesium alloys, and complete the early use of engineering in the field of cars.
