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 Zinc Oxide are homogenously mixed and reacted at controlled high temperature. The ferrite granules are crushed and consequently converted into ready to press powder by spray drying process. Powder compaction is done using precision presses. Sintering to achieve the required density, magnetic and dimensional features are done in precisely controlled furnaces. Sintered Ferrites are ground to achieve the required dimensions in close tolerances.

Quality System:
We are committed to quality and our quality policy is customer centered. Magnet manufacturing is supported by highest quality system, ISO-TS16949. Control Plans, APQP, PPAP, FMEA, Continuous Improvement, 8D problem analysis are inherent to Magnetic Product Division manufacturing.

Technology:
Ferrite core manufacturing is based on Ceramic Technology. Manufacturing is fully integrated with its R&D division and introduce technological advancements in the areas of process, products and new ferrite grades.

Ferrite Grades:
We offer most of the Soft Ferrite grades required to meet customer demand for across-the-board ferrite core requirements for applications such as – SMPS and other Transformers, telecommunication, RFID, Antenna, Compact Fluorescent Lamps(CFL), Electrode less Lamps (ELL).

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 magnetically “soft”.

The general composition of these soft ferrites is MeFe2O4, where Me represents one or several of the divalent transition metals such as Manganese (Mn), Zinc (Zn), Nickel (Ni), Copper (Cu), Iron (Fe) or Magnesium (Mg), the most popular being Manganese-Zinc (Mn-Zn) and Nickel-Zinc (Ni-Zn) ferrites. These compounds exhibit good magnetic properties below a certain temperature called the Curie Temp (Tc). These materials can be used up to very high frequencies without laminating. Ni-Zn ferrites have a very high receptivity and are most suitable for frequencies over 1 MHz however Mn-Zn ferrites exhibit higher permeability and saturation induction levels and are suitable up to 3 MHz.
