PRODUCT CATEGORY

A 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.

  • Ferrite Segment Magnet
    Ferrite Segment Magnet
    Brief:
    Ferrite segment magnets, also known as arc-shaped ceramic magnets, are typically used in motor stators and rotors. These magnets are formed into curved segments that fit around circular structures to create a uniform magnetic field. Made from sintered ferrite materials, segment magnets are cost-efficient, resistant to oxidation, and offer consistent performance in various mechanical environments.
    These magnets are widely used in household appliances, fan motors, and automotive electric motors where performance and affordability must be balanced.
  • Ferrite Ring Magnet
    Ferrite Ring Magnet
    Brief:
    Ferrite ring magnets, also known as ceramic ring magnets, are made from a composite of iron oxide and strontium carbonate. These magnets are a popular choice due to their excellent resistance to corrosion, low cost, and stable magnetic performance. With a central hole, ferrite ring magnets are easy to install onto shafts or within housings, making them suitable for a wide range of mechanical and electronic applications.
    Ferrite ring magnets are widely used in loudspeakers, motors, sensors, and holding systems. Their symmetrical design allows for even magnetic distribution, providing a balanced magnetic field ideal for rotational devices and axial assemblies.
  • Ferrite Disk Magnet
    Ferrite Disk Magnet
    Brief:
    Ferrite disk magnets are circular magnets with a flat profile made from iron oxide-based ceramic material. These magnets are widely recognized for their low cost, stable performance, and high resistance to environmental factors. The simple round shape is easy to integrate into various products, making them one of the most commonly used types of ceramic magnets.
    They are typically used in audio equipment, magnetic holders, toys, and small electronic appliances.
  • Ferrite Block Magnet
    Ferrite Block Magnet
    Brief:
    Ferrite block magnets are rectangular or square-shaped magnets made from ceramic materials. Known for their affordability, high resistance to demagnetization, and corrosion resistance, these magnets are widely used in industrial and commercial applications. Their large flat surface provides a strong magnetic holding force, suitable for various mounting and clamping needs.
    These magnets are especially common in magnetic assemblies, separation equipment, and general-purpose industrial tools.

  • Magnetic Assemblies
    Magnetic Assemblies
    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.
