Application of high performance NdFeB permanent magnet material
Gauss Industrial Co.,Ltd | Updated: Jul 27, 2018

In the rare earth functional materials industry, high-performance NdFeB permanent magnet materials are mainly used. High-performance NdFeB permanent magnet materials are mainly used in high-end applications such as new energy and energy conservation and environmental protection, such as EPS and new energy vehicles.

With the technological innovation of the automotive industry and the demand for energy conservation and environmental protection, low-energy, low-noise, low-emission electric or hybrid vehicles have become the goal of everyone. The bonded NdFeB magnet has the advantages of high magnetic performance, small volume and high efficiency. The motor efficiency of the NdFeB magnet is 8-50% higher than that of the ordinary motor, the power consumption is reduced by more than 10%, and the volume and weight can be reduced by 30%. the above. To realize the development of automobiles in the direction of miniaturization, light weight, high performance, energy conservation and environmental protection.

In addition, bonded NdFeB magnets are mainly used in micro-motors and sensors of medium and high-end automobiles. Each medium-to-high-end and luxury sedan uses 50 to 80 micro-motors, and some even have more than 100 units, with an average of at least 60. Above the station. Such as car seat motor, window motor, wiper motor, EPS power steering sensor, car CD or car hard disk, etc. As the car is comfortable, energy-saving, and automated, the NdFeB magnets used in automotive motors will increase. .

In addition to automotive use, the use of hard disk drives for bonded NdFeB is also high. The world has entered the information age, the perfection and development of magnetic storage technology and hard disk drive technology will definitely bring about the development of the big data storage industry, and the global hard disk demand will remain stable. Moreover, the development of cloud computing has high requirements for massive data, mass storage, and mass management of computers. As an important media of magnetic storage technology, hard disk is one of the important data storage methods today, and will develop with the development of cloud computing, which will bring a large market to the company's hard disk with bonded NdFeB magnets.

Not only that, but the emergence of ultra-thin hard disk drives presents new opportunities for bonding NdFeB magnets. In order to combat the impact of solid-state hard drives, the world's largest hard drive companies are planning to develop ultra-thin hard drives to meet the growing demand for the tablet market. The development of ultra-thin hard drives will bring new development opportunities for magnets for hard drives.

In 2011, affected by the national policy on the integration of rare earth industry, the price of rare earths fluctuated greatly, which had an impact on the production and operation of rare earth permanent magnet manufacturers and downstream customers. Some new application areas were suspended due to cost reasons; The gradual advancement of these policies and the implementation of some supporting measures will further standardize the management of rare earth mining, separation and circulation, so that the price fluctuation of rare earths will be reduced, the demand in the downstream market is expected to stabilize and the rare earth permanent magnets will be more energy-saving and environmentally friendly.
