How light a magnesium alloy steering wheel could be? Only weigh 0.5kg

    Date: 2022-10-24 Author:admin  

With the rapid development of the automobile industry, the speed of cars is getting faster and faster, the appearance structure is becoming more and more beautiful, the interior decoration is becoming more and more complex and diverse, and the internal technology content is getting stronger. The steering wheel has also changed quite a bit. Magnesium alloy is the lightest metal structure material, with high specific strength, excellent damping, shock absorption and noise reduction performance, good casting, machining and surface decoration performance, easy recovery and other advantages. The application of magnesium alloy in the steering wheel can achieve lightweight, and reduce the vibration of the road and control system. At the same time, when accidents occur, the magnesium alloy steering wheel can absorb more energy to ensure the safety of the driver, so it has the performance advantages that the traditional steering wheel, such as low carbon steel and engineering plastics, cannot compare. Therefore, it will be a safe and lightweight choice and trend to use magnesium alloy instead of other traditional materials such as steel and aluminum alloy to make automotive steering wheel skeleton.

With aluminum as the main alloying element, the toughness of the alloy gradually increases with the decrease of aluminum content. Therefore, the low-aluminum AM series magnesium alloy is more suitable for steering wheel and other safety parts. But, as the aluminum content is reduced, to a certain extent reduce the alloy casting, so, when choosing to achieve the required mechanical properties of alloy, shall ensure that high aluminum content in order to make sure its castability, therefore, choose high strength and good toughness and has certain casting properties of AM60B as the material of the steering wheel. According to the analysis of the data searched from the Internet, the series of magnesium alloys have good mechanical properties, elastic modulus E can reach 45 GPa, Poisson’s ratio ε is 0. 35, tensile strength σb≥200MPa, yield strength σs≥13OMPa, elongation δ≥6% (50mm standard distance). In weight, compared with the traditional iron, aluminum alloy in the material to reduce more than 30%; The process qualification rate of magnesium alloy steering wheel is equivalent to that of aluminum alloy steering wheel, reaching more than 85%; The performance is exactly what the steering wheel requires.


According to experts, cars of the future will be equipped with airbags. Due to magnesium alloy steering wheel light, shock absorption and safety. When airbags are installed in cars, almost all cars will have to have 100% magnesium alloy steering wheels. Due to the increase of private car demand and western development, the average growth rate of the total demand for cars in the next few years is about 10%. Using magnesium alloy instead of steel, aluminum alloy and other traditional materials to manufacture automobile steering wheel skeleton, the construction of magnesium alloy die casting automobile steering wheel production line. The production cost can be reduced by using one piece die casting process.

The following is the magnesium alloy steering wheel produced by Taishan Zhongmei  currently cooperate with Mercedes Benz, BMW, and BYD and other car companies .
