Extra Strong Neodymium Magnets

The remanence and energy product of neodymium magnets are higher than that of any other permanent magnets, so they are classified as very strong magnets(also called extra strong magnets). You can find very(extra) strong magnets in various fields of life and industry.

Available surface treatment for very strong neodymium magnetsThe main component of very strong magnet is iron, which is easy to be oxidized. Therefore, the surface of very strong magnet must be treated with anti-corrosion treatment before use. Please refer to the table below to select the appropriate coating.
