Dailymag Ferrite Magnets

Ferrite magnets are also called ceramic magnets. They are corrosion resistant making it suitable for water applications. Because of its low cost and excellent coercivity, it is suitable for low-cost applications including high-temperature motors, switches, DIY home projects, high-volume production runs, and more. Aside from that, these magnets are also non-conductive and electrically insulating. It is also perfect for applications that require high temperatures. Ferrite magnets are comprised of iron oxide and strontium carbonate to provide high strength and easy-to-magnetize features.

At Dailymag, we produce a wide range of ferrite magnets including ceramic disc magnets, ceramic pot magnets, ceramic ring magnets, and more. We offer custom services to different industries including industrial, commercial, consumer, etc. Our team provides the best solution, high-quality, on-time delivery, and competitive prices to meet your requirements.

Ferrite Magnet Applications

Ferrite Magnet Applications

  • Overband magnets
  • Motors
  • Generators
  • Loudspeakers
  • Meters
  • Marine applications
  • School projects
  • Security systems
  • Lifting machinery
  • Whiteboards
  • Switches, and more

Characteristics and Features

There are two different types of ceramic ferrite magnets including barium ferrite and strontium ferrite magnets. The iron structure of the magnet is already in stable oxidized conditions thus, it does not rust. Its corrosion resistance makes it suitable for marine, wet, or damp environment applications. These magnets are also designed with strong magnetic properties.

Aside from that, ferritic magnets are characterized by their dark gray color. The commonly used grade of ferritic magnets is C8 and C5. C8 magnets are widely used for loudspeakers while C5 is commonly used for overband magnets. Ceramic magnets are easy to be produced in any shape and size. It is typically machined through the grinding process.

Properties, Structure, and Composition of Ferrite Magnets

Properties, Structure, and Composition of Ferrite Magnets
Properties, Structure, and Composition of Ferrite Magnets

The magnetic properties of a ferritic magnet are classified as the following:

Soft Ferrites

Soft ferrites are widely used in electromagnetic cores or transformers. It is composed of manganese, zinc, and nickels. Its structure has low coercivity. However, it also has high resistance to eddy currents. The most common soft ferrites are the following:

  • Manganese-zinc ferrite
  • Nickel-zinc ferrite

Semi-Hard Ferrites

Cobalt ferrites are classified as semi-hard ferrite with properties that fall between hard and soft magnetic. These are commonly found in applications like actuators, sensors, and more. It features magnetostriction and is processed through magnetic annealing, uniaxial pressure, and assisted compact.

Hard-Ferrite

Hard ferrites are permanent ferrite magnets. It has high remanence and coercivity. These are manufactured using strontium carbonate and barium. It also features high magnetic permeability and low cost. There are two common hard ferrites:

  • Barium ferrite
  • Strontium ferrite

Bonding Methods of Ferrite Magnets
Bonding Methods of Ferrite Magnets

Commonly, ceramic or ferrite magnets are assembled using superglues. The typical bonding materials used are epoxies. When bonding ferrite magnets to different products, the surfaces are dried and cleaned first.

Chemical Composition
Chemical Composition

The ferrite magnets are composed of iron oxide and ceramic materials. It has a chemical composition of SrO-6(Fe203). The raw materials we used for producing ferrite magnets include iron oxide and strontium carbonate which are economical and abundant.

Temperature to Consider
Temperature to Consider

Ferrite magnets are suitable for a fair high-temperature range. However, their magnetic properties at a high temperature may decrease. Up to 75% of the magnetic properties at room temperature are retained at 175⁰C.

Safety Precautions
Safety Precautions

Ferrite magnets need to have special care when handled since these are:

  • Hard and brittle
  • Break or chip if snapped and dropped
Ferrite Magnet Ratings
Ferrite Magnet Ratings

Magnet ratings are the maximum strength of the materials to be magnetized. These magnets are commonly rated by the following:

  • Maximum energy product
  • Coercive force
  • Residual induction

What is a Ferrite Magnet?

A ferrite magnet is also called a ceramic magnet made from iron oxide and other elements such as strontium, zinc, nickel, barium, manganese, and more. These magnets are not electrically conductive. It comes in different types such as hard ferrites and soft ferrites.

What are the Hazards of a Ferrite Magnet?

Consider the following hazards before handling a ceramic magnet.

  • Breaking or chipping
  • Children should be supervised when playing with magnets
  • Wear gloves when using larger ferrite magnets to avoid cuts or blisters
  • Keep the magnet away from magnetically sensitive items to avoid damage
