Many parts in the car need magnets, and there are many types. I will not introduce them here. Today's article mainly talks about the demand for high-performance NdFeB magnets in traditional cars.
The application of high-performance NdFeB magnets in traditional vehicles is mainly electric power steering system (EPS). EPS steering system plays a key role in vehicle stability, comfort and safety. Automotive power steering systems can be basically divided into three categories, namely mechanical hydraulic power steering systems (HPS), electronic hydraulic power steering systems (EHPS) and electric power steering systems.
The development of EPS steering system in my country's automobile industry is slightly later than that of developed countries in Europe and the United States. In recent years, the penetration rate of EPS in my country's passenger vehicle market has increased rapidly, reaching 96.2% in 2020, but the steering system of commercial vehicles is still dominated by HPS and EHPS. . Although HPS and EHPS are low in cost, they consume a lot of energy and are easily damaged. Therefore, as the requirements for energy conservation and emission reduction become stricter, they will be gradually replaced by EPS in the future.
The automotive market in Europe and the United States has developed to a mature stage, and the EPS penetration rate is around 85%-90%. Therefore, there is still room for improvement in the EPS penetration rate in the domestic automotive market in the future, which will drive the demand for high-performance NdFeB to grow.
In 2021, the auto market will begin to recover. China's auto production will be 26.057 million units, a year-on-year increase of 3.5%; sales will be 26.248 million units, a year-on-year increase of 3.9%. It is expected that from 2022 to 2025, China's automobile production will continue to grow at a compound annual growth rate of 4%. According to the calculation that each EPS system needs 0.25kg of high-performance NdFeB magnets, by 2025, the global demand for high-performance NdFeB in the traditional automotive field will exceed 21,000 tons.
The above is the relevant introduction about the demand for high-performance NdFeB magnets in traditional automobiles. If you need to purchase and quote high-performance NdFeB magnets, please contact the Courage magnet manufacturer.
