Many parts of the car is the need for magnets, and many types, here not to expand the introduction, today's article focuses on the traditional automotive high-performance fishing iron.
Boron magnetic material needs. High-performance iron boron magnets in traditional automotive applications are mainly electric power steering system (EPS), EPS steering system has a key role in vehicle stability, comfort and safety. Automotive power steering system can be basically divided into three categories, namely mechanical hydraulic power steering system (HPS), electro-hydraulic power steering system (EHPS) and electric power steering system.
High-performance iron boron.
The development of EPS steering systems in China's automotive industry is slightly later than that of developed countries in Europe and the United States, EPS in China's passenger car market penetration rate has increased rapidly in recent years, reaching 96,2% in 2020, but commercial vehicle steering systems are still dominated by HPS and EHPS. HPS and EHPS, although lower cost, but energy consumption, easy to damage, so with the increasingly stringent requirements of energy saving and emission reduction. They will be gradually replaced by EPS in the future.
In 2021, the automotive market began to recover, China's automotive production of 26.057 million units, an increase of 3.5%; sales of 26.248 million units, an increase of 3.9%. China's auto production is expected to continue to grow at a CAGR of 4% from 2022-2025. Based on the need for 0.25kg of high performance Chintai boron magnet per EPS system, the global demand for high performance Chintai boron in the conventional automotive sector will exceed 21,000 tons by 2025.
The demand for high performance Chin-iron-boron magnets in traditional automobiles mainly includes the following aspects:
1.Engine control module: Modern automobiles rely more and more on electronic control systems to achieve precise engine control, so they need high performance Chin-iron-boron magnets as the core components of sensors and actuators.
2. Turbocharger: Chin-iron-boron magnetic material as a control component of turbocharger can improve the performance and response time of the supercharger, thus improving engine performance and fuel economy.
Overall, high performance Chin-iron-boron magnets play an important role in conventional vehicles to improve their performance and economy, as well as being one of the key technologies to achieve vehicle electrification.
