How can a strong magnet steal electricity? A powerful magnet is a neodymium iron boron magnet. Its magnetic properties greatly exceed the magnets such as ferrite magnets, aluminum-nickel-cobalt, samarium-cobalt, etc. The neodymium-iron-boron magnets are so strong that they can absorb objects 640 times heavier, and the rivers and lakes call them “strong magnets”. Because the [...]
How to Improve The Characteristics Of Magnetic Components At present, the development of modern industry is so rapid, and the use of magnetic components in life and work is becoming more and more extensive. MPCO Magnetic Products Co., Ltd. is also involved in the magnetic components. There are certain researches. Our company produces and sells [...]
ABOUT BONDED NEODYMIUM For a more flexible alternative to sintered neodymium, consider using bonded neodymium magnets for your application. Bonded neodymium powder is used to create these magnets. Powder is melted and mixed with a polymer. Components are then cast or extruded to create the product. Bonded Neodymium magnets can be magnetized into complex patterns [...]
Magnet Knowledge 1.How to order a magnet? In order to enable us to more effectively cooperate with your work, we need you to confirm the following before placing an order: (1). What is the material and performance? (2).What is the size and tolerance? (3). Which magnetized direction you need? Axial, diametrical? (4). The maximum temperature [...]
How To Find The Right NdFeB Magnets - Through Performance And Working Temperature According to the experience of MPCO for many years, a lot of customers didn’t know the professional knowledge of neodymium magnets. Therefore, the wrong choice has been made. In order to help customers to buy the right neodymium magnets. This paper explains [...]
Use of Magnets Permanent magnet applications in general can be divided into four categories, as follows: CATEGORY 1 Applications that make use of the tractive and/or repelling force of the magnet, i.e., the attraction between a magnet and a soft magnetic material, such as a piece of iron or steel, or the attraction or repulsion [...]
Permanent Magnet Magnetic Field Strength For magnet users, how to confirm the grade and magnetic properties are still a long standing issue. Most of users can’t get the value of main magnetic parameters by themselves. In this case, the relative measurement of magnetic properties is the best solution. The relative measurement of magnetic properties includes [...]
Hard Ferrite isotropic sintered multipole magnet ring Isotropic sintered ferrite magnets’ magnetic properties are low, they have nearly the same magnetic properties in all directions，can be magnetized in many different directions in multi-poles; Isotropic Ferrite Multipole Magnet Rings Ferrite isotropic sintered multipole magnet ring Dry Press radial multipole ferrite magnetic ring includes molding, [...]
Radially oriented anisotropic NdFeB ring magnets MPCO has developed a unique hot extrusion process to produce Radially oriented anisotropic NdFeB ring magnets. Unlike sintering, this process does not rely on a magnetic field for radial orientation. Our process starts with raw material powders manufactured by rapid quenching of the prescribed alloys into nanocrystalline flakes. These [...]
Injection molded magnets are made by injecting the special compound, a mixture of Nd magnet powder and high performance polymer, into the mold. These magnets cover a wide range of characteristics as isotropic bonded magents, including heat resistance and higher performance. Injection molding offers very flexible shape design as well as overmolding and insert molding [...]
Typical Compression Bonded Magnetic Properties Many suppliers publish specifications for a nominal 10 MGOe magnets with a minimum limit of 9 MGOe. Similar for a nominal 11 MGOe magnet; minimum limit is 10 MGOe. Have to design to lower limit of BHmax Typical Compression Bonded Magnetic Properties BHmax Improvement in Compression Bonded Magnets The BHmax of a compression bonded isotropic NdFeB magnet is influenced by the following two factors: 1. Volume fraction of magnetic phase in the magnet – typically measured by the density of the magnet. • We are investigating increasing the pressing pressure which requires special press construction, lubricants and tooling materials – current production pressing pressures are 7tonnes/cm2 for 5.9 g/cm3 and 10MGOe; estimated that > 20 tonnes/cm2 required for 6.3 g/cm3 and > 11 MGOe. • Optimize the particle encapsulation chemistry and process. • Tailored multimodal PSD’s for maximum packing density. • Particle shape control. 2. Magnetic powder Br/BHmax • Increase isotropic Br of powders while maintaining sufficient Hci to have “linear” B‐H demagnetization characteristic at the application temperature.

Your permanent magnet should lose no more than 1% of its magnetic strength over a period of 100 years provided it is specified and cared for properly. There are a few things that may cause your magnet to lose its strength: HEAT Heat above the maximum level rated for the magnet material in your separator [...]
