1. Low-carbon economy will detonate the development of new energy vehicles and the explosive growth of small and lightweight vehicles around the world, and drive the long-term demand for permanent magnet materials. The development of wind turbines has become an important fulcrum of rare earth permanent magnet industry. The technology of direct-drive permanent magnet wind turbine has entered a mature stage. At present, the market penetration rate in Europe and America exceeds 25%, while that in China is only 10%. The frequency conversion home appliance industry has become another focus to stimulate the demand of rare earth permanent magnet industry. The leaders of rare earth permanent magnet concept stocks are: Hengdian Dongci, Xiamen Tungsten, Baotou Steel, Ningbo Yun Sheng, Jiangxi Copper and Zhongke Sanhuan.
A permanent magnet means (once magnetized, it can) keep a constant magnetism. Permanent magnet material: a material with wide hysteresis loop, high coercivity and high remanence, which can maintain constant magnetism once magnetized. Also known as hard magnetic materials. In practice, the permanent magnet works in the demagnetization part of the second quadrant of the hysteresis loop after deep magnetic saturation magnetization. Commonly used permanent magnet materials are divided into permanent magnet alloy, permanent magnet alloy, permanent magnet ferrite, rare earth permanent magnet material and composite permanent magnet material. Permanent magnet motor: it is a kind of motor that uses permanent magnets to establish magnetic field, corresponding to excitation motor. Permanent magnet DC motor: A DC motor that uses permanent magnets to establish a magnetic field. Permanent magnet DC motors are widely used in various portable electronic devices or appliances, such as tape recorders, VCDs, record players, electric massagers and various toys.
3. It is also widely used in automobile, motorcycle, electric bicycle, battery car, ship, aviation, machinery and other industries. It is also widely used in some high-precision products, such as video recorders, copiers, cameras, mobile phone precision machine tools, bank ATMs, binding machines and so on. Although there is a connection, it is not absolute. Rare earth permanent magnet concept stocks rose greatly in the early stage. If the future increase is overdrawn, or the profit of the enterprise is lower than expected, the enterprise will still make money even if the spot price rises, but the stock will still fall. In addition, the rapid rise of the early market, the strong pressure of 3000, the real economy and policies do not support the continued rise in the next period of time. In the market correction, rare earth permanent magnet concept stocks may not be spared.
