PRODUCT CATEGORY

permanent ferrite magnet is an object made from a magnetized material and creates its persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials with the name ferromagnetic can be magnetized, which are also the ones that are strongly attracted to a magnet. These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field by several different types of magnetism.

※ Surface treatment for ferrite

A significant advantage of the strongest permanent magnet is that no surface treatment is needed because ferrite is inert and does not oxidize. It is always possible to coat ferrite magnets with various epoxy coatings when desired, for example, from the hygiene point of view.

※ Precautions when working with ferrite

Ferrite is hard and brittle. Pieces break off when the material falls. So it must be kept in mind when working with these magnets.

※ Why Us

Understanding permanent magnets / rare earth magnets and how their application can play into today's markets' innovative devices is our business's foundation. Kaiven Magnet supplies permanent magnets and magnetic assemblies to all industries across the globe.

Our main customer base is OEM businesses across various industries. However, anyone, including members of the public, is welcome to buy from us. If you cannot find the right magnet size, shape, type, grade, or the right magnet coating type, we can supply you. Custom made magnets can be low in cost - if the required quantities are large enough, production costs become low.

※ Guarantee

Prototype samples to mass production or stock items to custom design -KaivenMagnetics is a world leader in magnetic technology for providing solutions to your applications.

We can supply magnets with PPAP, FAIR, and CofC as required (please contact us to discuss your requirements before ordering). All our magnets are ISO9001 certified with RoHS and REACH compliance. We can supply magnets with PPAP or PSW to TS16949 as part of a custom production service. We also have 3D FEA software as part of our complete Technical Support Service.

    Brief:
    Magnetic materials, is an ancient and uses a very wide range of functional materials, and magnetic materials as early as 3000 years ago was that people understand and apply, for example, in Ancient China, as a natural magnet compass.Of modern magnetic materials have been widely used in our lives, such as permanent magnetic materials for motors, transformers used in the core material, as used in magnetic storage discs, computer floppy disk with magnetic recording and so on.Can be said that magnetic materials and information, automation, mechanical and electrical integration, defense, national economy is closely related to all aspects.Usually, that means over elements of magnetic material is iron, cobalt, nickel and its alloys can be produced directly or indirectly, of magnetic material.

    A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.
  • Ferrite Magnet
    Brief:
    Ferrites are usually non-conductive ferrimagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well as oxides of other metals. Ferrites are, like most other ceramics, hard and brittle. In terms of the magnetic properties, ferrites are often classified as "soft" and "hard" which refers to their low or high coercivity of their magnetism, respectively.
