With the rapid development of emerging industries, the demand for high-performance rare earth permanent magnet materials is expected to grow.

Nd-Fe-B is the main material of permanent magnet

Permanent magnetic materials, also known as hard magnetic materials, are characterized by high anisotropy field, high coercivity, large hysteresis loop area, and large magnetization field required for magnetization to saturation. After removing the external magnetic field, it can still maintain strong magnetism for a long time.

Permanent magnet materials work in the second quadrant demagnetization part of the hysteresis loop after deep magnetic saturation and magnetization. As an important basic magnetic functional material, it has a wide range of applications. China’s permanent magnet material industry plays an important role in the world. There are not only many enterprises engaged in production and application, but also research work has been in the ascendant.

According to industry practice, sintered Nd-Fe-B permanent magnet magnetic materials with the sum of intrinsic coercivity (kOe) and maximum magnetic energy product (mgoe) greater than 60 belong to high-performance Nd-Fe-B permanent magnetic materials. Coercivity, maximum magnetic energy product, remanence and maximum working temperature are the main parameters to measure the performance of permanent magnet materials. The first three indexes mainly measure the magnetic performance of materials. The higher the value is, the better the performance is. The working temperature measures the temperature resistance of magnets. According to the coercivity, sintered NdFeB magnetic materials can be divided into seven categories: bottom coercivity (n), medium coercivity (m), high coercivity (H), ultra-high coercivity (SH), ultra-high coercivity (Uh), very high coercivity (EH) and very high coercivity (th).

The raw materials of NdFeB magnetic materials mainly include rare earth metals such as neodymium, praseodymium, neodymium and dysprosium iron, as well as pure iron and ferroboron alloy. Praseodymium, neodymium and other rare earth metals account for about 60% of the cost of raw materials. From the cost structure of NdFeB processing enterprises, raw materials account for 60-80%. The fluctuation of rare earth price will affect the profitability of upstream smelting separation enterprises and NdFeB production enterprises, but NdFeB enterprises are less affected by price fluctuation.

Permanent magnet materials are mainly divided into rare earth permanent magnet materials, financial permanent magnet materials, composite permanent magnet materials and ferrite permanent magnet materials. NdFeB under rare earth permanent magnet materials is a widely used and rapidly developing magnet product. It is only 20 years since the invention of NdFeB. Because of its high magnetic properties and easy processing, the price is not very high, so the application field expands rapidly. At present, the magnetic energy product of commercial NdFeB can reach 50 mgoe, which is 10 times of that of ferrite. Nd-Fe-B also belongs to powder metallurgy products, and its processing method is similar to samarium cobalt.

Rare earth permanent magnetic materials are the third generation of permanent magnetic materials developed after metal system and ferrite system. Rare earth permanent magnetic materials have been developing rapidly since they came out in the 1960s. According to the time sequence of their development and application, they can be divided into four generations: the first generation is SmCo5 series; the second generation is Sm2Co17 series; and the third generation is NdFeB series, which was successfully developed in the early 1980s. Because of its excellent performance and low price, they are rapidly used in many fields The fourth generation is rare earth iron nitrogen and rare earth iron carbon. According to the estimation of experts in the industry, it will take at least several decades for the fourth generation of rare earth permanent magnet materials, which are expected to be mature and practical.

Table 2: development process of rare earth permanent magnet materials

The first generation SmCo5 They are all cobalt based permanent magnet alloys, but due to the high cost of raw materials, limited by resources and prices, they are mainly used in high-end fields.
The second generation Sm2Co17
The third generation NdFeB In 1983, it was discovered by Japan and the United States at the same time. It is called the third generation permanent magnet material. It is composed of a large number of neodymium, iron and boron, of which neodymium accounts for 25% – 35%.
The fourth generation Rare earth iron nitrogen (Re-Fe-N series) and rare earth iron carbon (Re-Fe-C series) At present, the fourth generation Fe-N (c) permanent magnet is still in the research and development stage. Among the existing three generations of rare earth permanent magnet materials, NdFeB has the characteristics of small volume, light weight, strong magnetism and so on. Due to the advantages of easy access to raw materials and low price, it develops very rapidly.

According to the different manufacturing process, NdFeB permanent magnet materials can be divided into sintering, bonding and hot pressing. They have their own characteristics in performance and application. The overlapping range of downstream application fields is relatively small. They play a complementary role rather than a substitute or crowding role.

China’s rare earth Nd-Fe-B materials are rising steadily, concentrated in Zhejiang

Since 2000, China has become the world’s largest producer of rare earth NdFeB permanent magnet materials. With the development of downstream applications, the output of NdFeB permanent magnet materials in China has been growing rapidly. During the 11 years from 2010 to 2020, the output of NdFeB permanent magnet materials in China has increased by 118%, with an average annual compound growth rate of 9.06%.

According to the data of China Rare Earth Industry Association in 2019, the output of sintered NdFeB blanks was 170000 tons, accounting for 94.3% of the total output of NdFeB magnetic materials in that year, bonded NdFeB accounted for 4.4%, and other total output accounted for only 1.3%. The data show that sintered NdFeB is the most widely used NdFeB material with the largest output.

Figure 6: Classification of NdFeB permanent magnet materials in China in 2020 (unit:%)
China’s NdFeB production capacity is mainly concentrated in Zhejiang, Shanxi, Shandong, Inner Mongolia and other places. Among them, Zhejiang has the advantage of industrial concentration, numerous enterprises and comprehensive development of industrial chain, with an annual capacity of 115600 tons, accounting for 38.7% of the total domestic capacity.

Output expected to continue to rise

It can be seen from the previous analysis that the global downstream consumption of NdFeB is distributed in the motor industry, public transportation and railway, intelligent robots, wind power generation and new energy vehicles. The growth rate of the above industries in the next five years will all exceed 10%, which will lead to the increase of NdFeB production in China. Although ferrite is the main component of permanent magnet materials at the present stage, the price and functional advantages of rare earth NdFeB are deeply remembered. It is predicted that the output of NdFeB in China will keep a growth rate of 6% in the next five years, and will exceed 260000 tons by 2025.
