The rare earth functional material industry is mainly based on high-performance NdFeB permanent magnet materials. High-performance NdFeB permanent magnet materials are mainly used in high-end application markets such as new energy and energy conservation and environmental protection, such as EPS and new energy vehicles.
With the technological innovation of the automobile industry and the human demand for energy saving and environmental protection, electric or hybrid vehicles with low energy consumption, low noise, and less exhaust gas have become the goal pursued by everyone. Bonded NdFeB magnets have the advantages of high magnetic performance, small size and high efficiency. The motor efficiency using NdFeB magnets is 8-50% higher than that of ordinary motors, the power consumption is reduced by more than 10%, and the volume and weight can be reduced by 30%. above. Realize the development of automobiles in the direction of miniaturization, light weight, high performance, energy saving and environmental protection.
In addition, bonded NdFeB magnets are mainly used in micro motors and sensors of mid-to-high-end cars. Each mid-to-high-end and luxury car uses 50-80 micro-motors, and some even as many as 100, with an average of at least 60 above the table. Such as car seat motor, window motor, wiper motor, EPS power steering sensor, car CD or car hard disk, etc. With the development of automobiles towards comfort, energy saving and automation, the number of NdFeB magnets used in automobile motors will increase. .
In addition to automotive applications, the application of bonded NdFeB in hard disk drives is also high. The world has entered the information age, and the improvement and development of magnetic storage technology and hard disk drive technology will surely bring about the development of the big data storage industry, and the global demand for hard disks will also remain stable. Moreover, the development of cloud computing has higher requirements for the massive data, massive storage, and massive management of computers. As an important medium for magnetic storage technology, hard disk is one of the most important data storage methods today. It will develop with the development of cloud computing, which will bring a larger market to the company's hard disk bonded NdFeB magnets.
Not only that, the emergence of ultra-thin hard disk drives brings new opportunities for bonded NdFeB magnets. In order to counteract the impact of solid-state drives, the world's largest hard disk manufacturers plan to develop ultra-thin hard disks to meet the increasingly popular tablet PC market demand. The development of ultra-thin hard disks will bring new development opportunities for hard disk magnets.
