Epoxy magnet is a kind of high performance magnetic material covered with a layer of anti-rust film, which can maintain its performance stability in wet environment for a long time. Because of its high temperature performance, high strength, good corrosion resistance and other characteristics, it can improve the service life and performance stability of various equipment.

Samarium cobalt magnet, is a rare earth magnet, with high magnetic energy product, very low temperature coefficient, the highest operating temperature up to 350℃, its maximum magnetic energy product (BHmax), coercivity (coercivity) and temperature stability and chemical stability are more than NdFeb permanent magnet material. It has strong corrosion resistance and oxidation resistance

Neodymium magnets are graded according to the material from which they are made. The higher the rating (the number after the "N"), the stronger the magnet and the higher the value. The highest grade of neodymium magnets currently available is N54. Any letters after the rating refer to the maximum temperature rating of the magnet. If there is no letter after the grade, the standard temperature of the magnet is 80 °C. Temperature ratings are standard temperature (no letter) followed by - M (100 °C) - H (120 °C) - SH (150 °C) - UH (180 °C) - EH (200 °C) - AH ( 220 °C) C)°C) For example: if the working temperature is 100 degrees, you need to select the H gear, and the temperature resistance of the magnet needs to be higher than the actual use.

1. Neodymium magnets are mainly composed of neodymium, iron and boron. The iron in the magnet will rust if exposed to air. 2. Thats why all the strong neodymium magnets in our factory are covered with protective coating, the protective coating is very thin (micron level) and has no effect on the adhesion of the magnet. 3. Neodymium magnets are available in many different coating and plating options. The most common coating for neodymium magnets is nickel plating. Although often referred to simply as "nickel plating," this nickel option is actually a three-layer plating consisting of a nickel layer, a copper layer, and a nickel coating. 4. Commonly used nickel (NI-CU-NI), zinc, copper, epoxy resin, gold, silver, passivation, PVC coating, etc.

Common directions of magnetization are shown in the figure below: 1>Disc, cylindrical and ring magnets can be magnetized axially or radially. 2> Rectangular magnets can be magnetized by thickness, length or width. 3> Arc magnets can be magnetized radially, by width or thickness.
