Sintered Neodymium Magnets are the world's strongest type of rare earth magnets. Made from an alloy of neodymium, iron, and boron, these magnets are extremely powerful for their small size and are used in many modern applications such as motors, phones, and headphones. These magnets are available in a variety of grades, from N35-N52, 35M-50M, 35H-48H, 30SH-45SH, and can be customized to various shapes, including blocks, arcs, rings, and custom shapes. The magnets can also be coated with nickel, NiCuNi, zinc, epoxy, or other coatings to protect them from corrosion, scratches, and other damage. With a working temperature of 80~220°C, these sintered neodymium magnets are a reliable and powerful choice for many applications.
