Scientists Find That Some Magnetic Materials Freeze When Heated Physicists have found that some magnetic materials freeze when the temperature rises above a certain level. Usually, freezing occurs only when an object is cooled, not when it is heated. So this leaves physicists scratching their heads and bewildering. Heating but freezing? Alexander Khajetoorians, a physicist [...]
Development of Zinc Oxide and Magnetic Materials In zinc-manganese ferrite cores, zinc oxide is the main raw material. In the production of medium and high-grade ferromagnetic materials, the high-end zinc oxide of the zinc oxide varistor grade produced by the indirect method must be used. The development of permanent magnet materials has promoted the scientific [...]
Soft Ferrite Cores Chemistry of Soft ferrites: Our wide ranges of soft ferrite cores are made from Manganese Zinc Ferrite (MnZnFe12O9).Chemistry of various soft ferrite grades are closely controlled by using X-ray Fluorescence Spectrometer (XRF). Process of Ferrite magnet manufacturing: Ferrite manufacturing is based on Ceramic Powder Technology. High quality Iron oxide, Manganese oxide and [...]
Soft Ferrites Ferrites are polycrystalline oxides manufactured by ceramic technology and belong to a class of materials that exhibit the technically useful property of ferromagnetism. In a ferromagnetic material, magnetism occurs under the influence of an externally applied field. On removals of this field, material returns to its non-magnetic state. This behaviour is termed as [...]
Ferrite Blocks / Ferrite Plates / Ferrite Tiles MPCO´s ferrite blocks and plates are suitable for a wide range of applications, for example induction heating, as components for antennas or for magnetical shielding. Thanks to their particular flat surface they are ideally suited for building ferrite assemblies like transformers in the kilowatt range. In version [...]
New shapes / Special ferrites / Custom-build ferrite shapes But we don't just specialise in inserting air gaps or reshaping standard cores; we also machine completely new core shapes, or existing shapes but to new dimensions. We can manufacture these entirely to our customers' requirements - in small quantities or in millions. Above all, our [...]
Customized Ferrite Machining Are you looking for a matching air gap or AL-value for your Ferrite or toroidal core or a customized special ferrite core? We are machining ferrite cores according to your requirements or design and manufacture totally new shapes and sizes. Customized Ferrites / Air gaps / Special Ferrites / Ferrite machining / [...]
Ferrite cores with distributed air gaps Lower losses due to distributed air gaps in ferrite cores In order to achieve lower losses in ferrite cores, individual air gaps are usually inserted into the cores. This leads to a delay in core saturation. However, large air gaps increase the magnetic stray fields and thus cause additional [...]
Large Volume Ferrite Cores Large ferrite cores for applications in power electronic. for example: E cores up to E480, U-cores up to U320, PM-cores up to PM178, torodial cores up to T154 Large-volume Ferrite cores for high power Large Ferrite cores are used in many fields of power electronics such as solar technology (e. g.

What Are The Most Common Materials For Magnetic Cores? As we know, the inductor core materials there are many the main iron core, silicon steel sheet core, FeSiAlF core, Mn Zn ferrite core, Ni Zn ferrite magnetic core core. Among them, Mn Zn ferrite core, Ni Zn ferrite magnetic core are ferrite cores. Do you [...]
Brief Introduction Of Ferrite Core Ferrite core is mainly composed of iron (Fe), manganese (Mn), and zinc (Zn) three metal elements, commonly known as manganese-zinc ferrite. Because the annular ferrite core has no air gap and the cross section area is uniform, the magnetic effect is very high. Ferrite rings have a wide range of [...]
3D-printed Permanent Magnets Outperform Conventional Versions OAK RIDGE, Tenn., Nov. 1, 2016—Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated that permanent magnets produced by additive manufacturing can outperform bonded magnets made using traditional techniques while conserving critical materials. This isotropic, neodymium-iron-boron bonded permanent magnet was 3D-printed at DOE’s Manufacturing Demonstration Facility [...]
