KINGS MAGNET® supports customized neodymium magnet blocks from 1-300mm. Magnet grades, magnetization directions, and coatings can be selected according to your application.
Sintered NdFeb permanent magnet materials are divided into six types of products according to the coercivity of magnetic pole strength: low coercivity (without letters), medium coercivity M, high coercivity H, extremely high coercivity SH, ultra-high coercivity UH, extremely high coercivity EH.
Unlike gold, zinc and nickel, an epoxy magnet coating acts as an excellent barrier to salt, ambient air, water or moisture. But it's slightly more expensive than the first three alternatives. Although it is easy to scratch, with a thickness of 15-30 um, it has good adhesion to steel with magnetic glue. Epoxy coatings are mainly used in the Marine, motor, sensor, automotive and consumer goods industries.
The surface treatment of NdFeb magnet is not to improve its performance, and the surface coating of neodymium magnet mainly plays a protective role. No surface coating of NdFeb strong magnets, it is easy to react with oxygen in the air and quickly oxidize, so in order to prevent this from happening, we usually carry out plating treatment. Moreover, the appearance of the strong magnet after electroplating is more beautiful.
Neodymium(NdFeB) magnets are the strongest type of rare earth magnet commercially available and are manufactured in a wide range of shapes, sizes and grades.
