Concerned about the development trend of magnetic materials in China

In 2008, the US subprime mortgage crisis and its subsequent global financial crisis spread to all countries in the world, disrupting the normal global economic order. Affected by the global economic and financial crisis, China’s economic growth momentum, which has been maintained for many years, has slowed down and the momentum of growth has exceeded expectations. Magnetic materials, as China's products with advantageous exports, have been severely hit by the rapid decline in the consumer market in Europe and America, and the industry situation is extremely grim. However, there are many opportunities hidden in this dangerous stage of industrial downturn. Therefore, magnetic material industry enterprises understand in a timely manner. Domestic and foreign economies, industry trends, and market dynamics, it is particularly important to grasp the direction of market development, improve internal strength, and respond well to market changes.
China's magnetic material products are mainly dominated by middle and low-end products, and domestic competition is fierce. In particular, the sharp rise and fluctuation in energy, raw materials, and labor costs in recent years have led to rising production costs, difficulty in enterprise cost management, and cost control. Magnetic material companies generally present The situation of increasing and decreasing profits.
Changes in Market Environment of Main Application Fields of Magnetic Materials in China
Automotive and Automotive Electronics Market
Magnetic electronic components are widely used in automotive electronics. The main applications include the following three main areas: First, traditional electronic products, such as car audio, automotive instrumentation, automotive lighting, etc.; second is to improve vehicle safety, stability, comfort And entertainment products, such as ABS, airbags, power control systems, chassis control, GPS, etc.; third, energy-saving and environmentally friendly electric vehicles and hybrid vehicle systems, such as chargers, motor drives.
At present, there are more than 40 permanent magnet motors used in high-end automobiles, and a large number of permanent magnet ferrites and rare earth permanent magnets are used. Instrumentation and instrumentation sensors also use aluminum nickel cobalt and samarium cobalt permanent magnets, and soft magnetic materials are used in automobiles because of their characteristics. Electronic is more widely used.
Soft magnetic ferrite for electric vehicle (EV) charging devices. The inductive charging system (ICS, Inductive Charging System) has the disadvantages of contact type, safety, reliability and stable performance. It represents the development direction of charging technology. In this charging mode, there is a soft charge for both the charging station and the car. A large, flat pot core made of ferrite material in which coils are embedded. When charging, the two coils are close to form a transformer, and the high-frequency AC power is fed from the charging station to the battery pack by the magnetic induction coupling between the primary and secondary, and the low-loss power ferrite such as TDK PC44, PC47 or FDK 6H40, 6H45 is used to make the magnetic coupling device. The more suitable magnetic core material.
Soft magnetic ferrite used in HEV powertrains. In order to realize complex power conversion and transmission functions, HEV power systems use multiple power conversion transformers and chokes. In order to ensure long-term reliable operation in harsh environments and maintain high efficiency, the cores of these transformers and chokes are made of high-performance, wide-temperature, low-loss-power ferrite materials such as TDK PC95 or FDK 6H60. And other materials. One of the core components of a hybrid car is a DC-DC converter for power conversion, in which a high-performance, wide-temperature, low-loss ferrite core similar to TDK PC95 is used, which is a promising high-end market in the future.
Home Consumer Electronics Market
Magnetic materials are widely used in home consumer electronic products, and China is already a major exporter of home appliances. Changes in the home appliance market will stimulate or inhibit the growth of magnetic electronic components.
Consumer electronics has always been the largest market for magnetic materials in China, but consumer electronics have undergone qualitative changes. Flat-panel TVs replace traditional CRT TVs and digitalization has become mainstream. Because of the environmental electromagnetic pollution caused by electromagnetic wave interference on various types of electrical appliances, green environmental protection has been mentioned at the top of the list at home and abroad, and electrical appliances without electromagnetic compatibility and anti-electromagnetic interference are prohibited from being sold. Therefore, magnetic cores that resist electromagnetic interference will have a large number of applications.
Each LCD TV backlight inverter uses 12 to 26 ferrite cores, so this will undoubtedly become the most important new economic growth point for the soft ferrite industry in the near future.
TVs have always dominated consumer electronic products in China. The hot spot for development in the future is high-definition, large-screen, and digital transition. Flat-panel TVs will account for about 60%. This makes the use of magnetic materials more stringent:
1. High-frequency, requires ferrite power core has a higher operating frequency;
2. High-definition, requiring power transformer power stability, material power loss, saturation magnetization;
3. The image is stable, colorful, and requires the use of high magnetic permeability materials, anti-electromagnetic interference soft magnetic core and high performance focusing film;
4. The development of digitization has higher requirements on the power loss, magnetic permeability, and frequency of use of soft magnetic materials than simulations.
5. The IEA stipulates that the standby power of color TVs should be reduced to 1W, which puts forward new requirements for low-loss power ferrite materials.
Digital video and audio equipment require a large number of magnetic components that are small in size and resistant to noise interference, and most of them use patch components.
In terms of lighting engineering, the use of semiconductor light-emitting diodes (LEDs) is advocated for further energy savings. If this is widely promoted, the demand for ferrite soft magnetic is extremely high. In addition, a variety of new energy-saving light sources, such as HID, LED, high-pressure sodium lamps, high-frequency stepless lights, etc. are also increasingly widely used, most of the green lighting equipment must use soft ferrite cores as power and filter components. With regard to the development of new energy sources, the development of solar energy, wind energy, and hydropower will increase the demand for permanent magnets and soft ferrites.
