Neodymium-Iron Boron Magnets: Neodymium-Iron Boron magnets are currently the highest-performing magnets commercially available, known as the "magnet king," with extremely high magnetic properties. Their maximum energy product (BHmax) is more than 10 times that of ferrite magnets. Therefore, they are also commonly known as "high-intensity magnets," "magnetic steel," etc. Their mechanical processing properties are also quite good. The working temperature can reach up to 200 degrees Celsius. Moreover, they are hard and have stable performance, making them very cost-effective. Therefore, their applications are extremely wide. However, due to their strong chemical activity, surface treatment is necessary.
