How to remove impurities in NdFeB permanent magnet materials

How to remove impurities in NdFeB permanent magnet materials in finished products? The processing of NdFeB magnets is basically carried out under vacuum conditions, and impurities are not easily mixed. Since the chemical properties of NdFeB permanent magnet materials are relatively active, impurities are incorporated into the oxidation of the metal. Therefore, the finished product [...]

(2) Ferrite magnet: a kind of permanent magnet [...]

Neodymium Iron Boron

Neodymium Iron Boron (NdFeB) is another type of rare earth magnetic material. This material has similar properties as the Samarium Cobalt except that it is more easily oxidized and generally doesn't have the same temperature resistance. NdFeB magnets also have the highest energy products approaching 50MGOe. These materials are costly and are generally used in [...]

Ironcore Flat Linear Motor

Ironcore Flat Linear Motor, U-Channel Ironless Linear Motor: Direct drive linear motors have high force density, high stiffness, enable extremely smooth velocity control and require minimal maintenance. Ironless linear motors typically consist of a U-shaped magnet track, with two plates of magnets facing each other. This reduces heat dissipation and means that ironless linear motors [...]

Decrypt NdFeB Magnets

Decrypt NdFeB Magnets - The formation of a magnetic field is a magnetic field generated by a molecular ring current of a magnetic substance, and the direction of movement of atoms or ions outside the nuclear electrons is random, so a large number of atom synthesis current is zero, no magnetic field, such as ferric [...]

NdFeB Plating Difficulties

NdFeB Plating Difficulties 1.The chemical activity in the material is extremely strong Neodymium iron boron parts even when in contact with water will produce hydrogen and corrosion,so: ①The use of acid and alkali before plating treatment should not be too strong, otherwise the material matrix is susceptible to corrosion, and the reaction between chlorine and [...]

Magnet Temperature Effects

Magnet Temperature Effects Magnetic properties of all the permanent materials change with temperature. Remanence, and thus the magnetic flux a magnet produces, decreases in all magnetic materials with increasing temperature. Ultimately, at certain, for each material characteristic temperature the material becomes non-magnetic. This temperature is known as Curie temperature (Tc). Figure 1 illustrates the temperature [...]
