Neodymium Iron Boron Magnets
Sintered neodymium magnets (also known as NdFeB magnets) consist of a neodymium, iron, and boron alloy that forms the Nd2Fe14B tetragonal crystal structure. Neodymium magnets have the most powerful magnetic dwellings on the market today. They come in many shapes, sizes and grades. The new magnets can be used in many projects, including motors with exceptional overall performance, brushless DC motors, magnetic separation, magnetic resonance imaging, sensors, switches, and speakers.
Sintered neodymium magnets (also known as neodymium-iron-boron magnets) are the most common form of the less common earth magnet.
They include neodymium, iron and boron alloys that form the Nd2Fe14B tetragonal crystal structure. Neodymium magnets have the most powerful magnetic dwellings on the market today.

Quick Facts about Neodymium Magnets
Required saturation magnetization field: ≥ 33 kOe.
Manufacturing methods - sintering (maximum common), injection molding, laminating, or calendering.
Available shapes blocks, rods, discs, rings, arc segments, etc.
Available grades: Current the highest grade N58
Machining: Neodymium magnets should be grinded by diamond wheels. Compare to other magnetic material, such as AlNiCo, SmCo, NdFeB magnets are relativer easier to machine. With advanced technology, we can machining mirco with size 0.1mm and can processing the magnets with strange shape.
Maximum carrier temperature and corrosion
Determining whether or not to apply a brand new magnet relies upon, for example, at the most temperature of the application, the specified magnetic output at regular use temperatures, and the entire value of the system.
New magnets have a few boundaries because of their corrosive behavior. In moist applications, using shielding coatings is especially recommended. Coatings which have been used correctly encompass epoxy coatings, nickel plating, and combos of those coatings. We are likewise capable of observe poly- parylene coatings to new magnets. The effectiveness of the coating relies upon at the great of the substrate. magnet magnetic cloth has evaluated the substrate corrosion resistance of numerous producers and simplest gives licensed, especially corrosion resistant substances produced below strict controls.
