neodymium magnet
May 30, 2018

ND-FE-B, neodymium magnet refers to NdFeB, Simple is a magnet, and we usually see the magnet is different, because of its excellent magnetic properties known as the "Magnetic King."
Neodymium-iron-boron contains a large number of rare earth elements neodymium, as well as iron and boron, its characteristics are hard and brittle. As the surface is easily oxidized, ND-FE-B must be treated with surface coating.
Surface chemical passivation is one of the best ways to solve the problem.
As a kind of rare earth permanent magnetic material, ND-FE-B has very high magnetic energy product and coercive force, at the same time, the advantages of high energy density make ND-FE-B permanent magnetic materials in modern industry and electronic technology has been widely used, so that instrumentation, electro-acoustic motor, magnetic magnetization and other equipment, such as miniaturization, lightweight, thin form of the possibility.
ND-FE-B has the advantage of high cost-performance, good mechanical properties, low temperature, poor temperature, and easy to powder corrosion, it is necessary to adjust its chemical composition and adopt surface treatment method to improve it, in order to achieve the actual application requirements. NdFeB magnetic materials, as the latest development of rare earth permanent magnets, are known as "magnetic Kings" due to their excellent magnetic properties. ND-FE-B magnetic material is the alloy of praseodymium nd metal, boron iron and so on.
Also known as magnetic steel.
