Atech Neodymium Iron Boron Magnet
It's also well known as NdFeB, NIB or Neo magnet, the most widely used type of rare earth magnet; It is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure.Multiple choices of shapes can meet specific customer requirements.
Magnet Grades
The Grade of a magnet generally indicates how “strong” a magnet material is, which is measured by the Maximum Energy Product. The energy product is commonly specified in units of Gauss Oersted. The higher the grade the “stronger” the magnet.
Atech Neodymium Permanent Magnet are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52. and M, H, SH, UH, EH, AH series,can be customized into a wide range of shapes and sizes with higher heat resistance. Multiple choices of coatings and magnetization orientations can meet specific customer requirements. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C) to AH (230 °C)

Magnet Coatings
As Neodymium magnet is prone to corrosion, it is usually preferable to be coated for protection. Among a variety of options for coatings, nickel and nickel-copper-nickel are the most commonly used, making the magnet more corrosion resistant and durable.
Magnetization Orientations
Our magnet products can be delivered magnetized and un-magnetized. Some production methods require the magnets being incorporated into assemblies in a un-magnetized state and magnetized later once the assembly is completed. There are various magnetic orientations available for different shapes of magnets.
