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 [...]
Isotropic polymer bonded SmFeN magnets Sm-Fe-N magnet powders are produced in a similar way to Nd-Fe-B, except that nitrogen is introduced by heat treatment of rapidly quenched Sm-Fe flakes in a nitrogen atmosphere. These flakes are then mixed with a polymer binder and pressed or injected to make isotropic bonded magnets. Magnetic performance of (BH)max=112 [...]
Isotropic Bonded NdFeB Magnets Coatings Compression molded magnets kept in dry air will be rust free for a long time. However, in a humid environment, the moisrure in the air will cause rust on the surface. Therefore surface coating is necessary for most applications. MPCO provides 5 types of coatings for your specific shape and [...]
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 [...]
Isotropic polymer bonded NdFeB magnets - The raw material powder is manufactured by rapid quenching of prescribed alloys into nanocristalline flakes which are subsequently annealed for optimum magnetic properties. Shortly after the invention of rapidly quenched NdFeB magnet powders, MPCO had started to develop polymer bonded magnets from these powders. Isotropic polymer bonded NdFeB [...]
The Brief Introduction about Magnetic Boiler Filter The central heating system is a relatively energy-efficient way to heat all of rooms in home. The central heating system of China quite different from other Western countries, and only the people north of the Qinling Mountain-Huaihe River Line can enjoy the central heating, so this line is [...]

Neodymium Price Increase Explanation Letter to Valued Customers Dear Valued Customer, You may already feel that recently our prices for Rare Earth Neodymium magnets have increased quickly and the validity of price is shortened. We understand this may have caused inconveniences. However, we think it’s necessary to explain the current situation and also express our [...]
MPCO Magnetics Starts to Use Water-based Cutting Fluid The cutting fluid is an essential accessory material to the cutting process. For NdFeB magnet, the grinding heat at grinding area will reach 1000 to 1500 deg C during the slicing and grinding processes, the NdFeB magnet is likely to appear spot annealing, surface burning, oxidation, crack [...]

Available as either absolute or incremental encoders they can provide digital position, analog position, and quadrature speed outputs. Capable of rotational speeds over 20k RPM. Hall IC used for this application uses a diametrically magnetized magnet. Hall Effect through‐shaft encoder. Requires use of Hall IC capable of off‐axis sensing using multipole bonded magnet. Low cost, speed or position sensors typically seen in automotive applications – Cam position, crank position, engine speed, ABS. This type of sensor can be designed for either face or lateral sensing applications and may, in addition to the Hall IC, incorporate a magnet if sensing a metal target or a pole piece if sensing an encoder multipole magnet. What is the best permanent magnet material and process? •It depends; on the weight/space limitations, application operating conditions, operating parameters of the magnetic circuit, annual quantity, device assembly mechanization etc. • Despite have lower flux output bonded magnets can offer advantages over sintered magnets for many applications. • Despite lack of breakthrough in new materials over the last 30 years there are several promising developments in bonded magnets on the horizon. • [...]
TESTING MAGNET Because magnetic fields are transparent to the human eye, measuring their strength requires specialized tools that measure the working air gap of the magnetic circuit. Currently there are two accepted ways of testing your magnetic separation equipment and this subject itself is not without controversy. The first is with the use of an [...]
