Sintered NdFeB magnets are widely used in all walks of life in the current era of rapid development. NdFeB is easy to oxidize and needs a protective layer, which is called electroplating and surface treatment. Because the elements nd and Fe in NdFeB permanent magnets are easy to corrode and oxidize, the corrosion resistance and oxidation resistance of sintered NdFeB permanent magnets are poor, The...
Now the price of magnet raw materials on the market is more and more expensive, and the project funds are limited, how to improve the efficiency of the magnet? There is a type of magnet called pot magnet, which is a combination of a magnet and an iron shell. A magnet of the same size in an iron shell is stronger and cheaper than a separate magnet. Why does adding an iron shell make the suction str...
Production technology of Nd-Fe-B magnet 1. Raw material preparation and pretreatment: Process Description: pretreatment of raw materials such as weighing, crushing, material breaking and rust removal. Process equipment: steel bar cutter, drum polishing machine, etc 2. Melting: Process Description: the pretreated raw materials praseodymium neodymium, pure iron, ferroboron, etc. are proportioned and...
With the development of society, magnets are more and more widely used, from high-tech products to the simplest magnetic packaging. At present, Nd-Fe-B magnets and ferrite magnets are most widely used. From the development history of magnets, man-made magnets appeared in the 18th century, but the process of manufacturing stronger magnetic materials is very slow. At the end of the 19th century and ...
Rubber magnet is made of hard ferrite material mixed with polymer. It has the characteristics of low hardness and good plasticity. It can be processed into various plane shapes such as sheet, strip, square, round and so on. Due to the high plasticity of the material itself, the finished products or semi-finished products can be cut, perforated and mounted with other materials at will, which is not...
The magnet creates a fixed magnetic field in the generator. The coils of the generator move in the magnetic field, and the coils cut the magnetic field to generate electricity. This is electromagnetic induction. There are many types of generators, all of which operate on the principle of electromagnetic induction. Generators with permanent magnets are called permanent magnet generators. When a wir...
Hook magnet is an innovative magnetic product that can help lift items such as wires and cables safely to reduce the risk of them becoming tripping hazards in the workplace. Any environment with a metal surface is suitable for hanging or hanging materials from the magnetic hook. Super magnetic hooks are part of the neodymium magnet category, which also includes accessories options for countersunk ...
1. Ndfeb permanent magnet is a modern permanent magnet with strong magnetism. It is also widely used. The application situation of Ndfeb magnets in China is as follows, the application of high-tech products accounted for 37%, such as Magnetic Resonance Imaging (MRI), mobile phone vibration, hard disk drive voice coil (VCM), optical disk (DVD, CD-ROM) drive spindle, power tools, electric vehicles, ...
