Why Magnets Broken So Easily?

Why Magnets Broken So Easily? A: The magnet contains B, which enhances the magnetic force, but the physical properties are easily broken. In the production process, it is usually used with slow air flow powder, advanced technology and long sintering time, lack of flexibility The magnet attaches something else under a strong magnetic field. It [...]

Bonded Magnets: A Versatile Class of Permanent Magnets

Bonded Magnets: A Versatile Class of Permanent Magnets Permanent magnets are ubiquitous in modern societies. Devices that use permanent magnets include motors, sensors, actuators and acoustic transducers. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment and more. It is estimated, for example, that a [...]

What is Bonded NdFeB Magnets

What is Bonded NdFeB Magnets Bonded NdFeB Magnets are produced by melt spinning a thin ribbon of the Nd-Fe-B alloy. The ribbon contains randomly oriented Nd2Fe14B na no-scale grains. This ribbon is then pulverized into particles, mixed with a polymer and either compressed or injection molded into bonded magnets. Bonded magnets offer less flux than [...]

HOT FORMED NdFeB MAGNETS (MQ3)

HOT FORMED NdFeB MAGNETS (MQ3) Hot Formed NdFeB radially oriented ring magnets are produced by a unique hot extrusion process. As base nanocrystalline powder material is used made by rapid quenching (Neodymium) alloys. This powder material is hot pressed and then hot extruded into ring-shaped magnets. During this advanced hot extrusion process the radial orientation [...]

PLASTIC BONDED NdFeB MAGNETS (MQ1)

PLASTIC BONDED NdFeB MAGNETS (MQ1) Plastic Bonded NdFeB magnets are manufactured by binding rapidly-quenched nanocrystalline NdFeB powder with polymer binders. These plastic bonded magnets have an isotropic material structure. Different types of binders can be used depending on the requirements. Several techniques for producing plastic bonded NdFeB magnet types are available: Compression Moulding After mixing [...]

Aligning Field for Anisotropic Bonded NdFeB Magnets

Residual Magnetic Flux Density Distribution Calculation Considering Effect of Aligning Field for Anisotropic Bonded NdFeB Magnets Abstract This paper presents a calculation method of residual magnetic flux density distribution for a four-pole anisotropic bonded NdFeB permanent magnet (PM) considering the effect of aligning magnetic field during the forming process. To manufacture the anisotropic bonded NdFeB [...]

Sintered NdFeB Magnets as Anisotropic Bonded Magnets via Hydrogen Decrepitation Process

Sintered NdFeB Magnets as Anisotropic Bonded Magnets via Hydrogen Decrepitation Process Abstract The scrap sintered Nd–Fe–B magnets were recycled as the raw materials for bonded magnets using the hydrogen decrepitation (HD) process. The HD powders have the lowest oxygen and hydrogen content by hydro-genation at 150°C with 1 bar H2 pressure and dehydro-genation at 600°C. [...]

Magnetic Material Classification

Magnetic Material Classification, The classification of magnetic material According to the magnetic  material under action of external magnetic field, the material is divided into anti magnetic material, anti ferromagnetic material, magnetic material. The latter two are strong magnetic material, magnetic material is widely used in science and technology. Magnetic materials classification generally divided into metallic [...]

Crazy Rare Earth

Crazy rare earth, Rare Earth Magnet Rare earth is not earth. Rare earth containing lanthanum, cerium are: metal, praseodymium, neodymium, samarium, europium, promethium......" There is oil in the Middle East, China with rare earth." This is Deng Xiaoping\'s southern tour in 1992 when the "logion". However, from 1990 to 2005, exports of rare earth China [...]

Injection Molded Ferrite Magnets

Injection molded ferrite magnets Injection molded Ferrite is another molding process of magnet category. Compared to injection molded NdFeB, the difference of injection molded Ferrite lies in different magnetic powder utilized, therefore injection molded ferrite has lower magnetic properties due to ferrite features, but it costs much less than that of NdFeB. Injection Molded [...]

Plastic Magnets Characteristic

Plastic Magnets Characteristic Plastic magnet is different from the traditional magnetic craft which made by mixing the magnetic particle with plastic medium, mixed and heated by the injection machine and then rip the mixture into the mould to get different shapes of production, this kind of process makes the plastic magnetic has some unique advantages: [...]

Pressless Process Magnet PLP

About Pressless Process Magnet / PLP magnet The high-coeacivity magnets show a growing demand in recent years due to the rapid development of the hybrid electric vehicle (HEV) and the electric vehicle (EV). In order to ensure the high-temperature stability, the manufacturer will use Dysprosium element to substitute part of Neodymium element. As a kind [...]

Recycling NdFeB Magnet

Recycling NdFeB Magnet Rare earth elements have been becoming a critical part of everyday life and advanced technological development during the past several decades. The rare earth demands are rising and its supplies are in question due to Chinese government export duties. Hence price issue of rare earth element has been widespread concerned. It is [...]
