What industry does strong magnet have an impact on?
November 02, 2021

1. Strong magnet is called permanent magnet. According to the principle, demagnetization has nothing to do with time. There are two main factors causing demagnetization of magnet, temperature and oxidation. If the temperature is too high, it will lose magnetism if it exceeds Curie temperature by 300 ℃. If the protection is not good, it will also lose magnetism if it is oxidized, which is also the biggest reason for the failure of the magnet during use. Strong magnet has the characteristics of small volume, light weight and strong magnetism. It is the magnet with the best performance price ratio so far. As the third generation of rare earth permanent magnet materials, magnets have high performance price ratio. They are widely used in energy, transportation, machinery, medical treatment, it, household appliances and other industries. Especially with the development of knowledge economy represented by information technology, they continue to bring new uses to functional materials such as rare earth permanent magnet industry, which brings a broader market prospect for Nd-Fe-B industry.

2. How to make sintered NdFeB permanent magnet is an iron-based permanent magnet made by powder metallurgy process. The main processes include formula smelting, powder making, forming, oriented sintering, machining, electroplating, etc. The control of oxygen content is an important index to measure the process level. Even after a long time of use, the magnetic properties TEDS of a magnet is the magnetic field energy generated by unit volume data, and a physical quantity of the energy that a magnet can store. Commonly used magnetic measuring instruments commonly used magnetic measuring instruments include fluxmeter Tesla meter, also known as Gauss meter magnetic measuring instrument. The magnetic flux meter is used to measure the magnetic flux, and the magnetic flux meter is used to measure the comprehensive magnetic performance.

3. The strong magnet is made by pressing the powder produced after hydrogen crushing of raw materials. The initial shape is called blank. Later, it can be processed into different shapes according to customer requirements, such as wafer shape, ring shape, square shape, perforated shape, trapezoid and some irregular shapes. The performance of a strong magnet is different according to different magnetic energy products. Strong magnets are the main supporting products of various electronic products. Both consumer household appliances and industries such as computers, communication equipment, automobiles and national defense industry are inseparable from magnetic materials. The medium and long-term market prospect of magnetic materials is very bright, and China's magnetic material products will further improve their position in the world.
