Ceramic Magnet Grades

Ceramic magnets, also known as ferrite magnets, is a type of permanent magnets made of iron oxide and strontium carbonate. we carry the grade C8 ceramic magnets, which is the strongest ceramic magnet. Ceramic magnets are widely used as craft magnets and refrigerator magnets.

Material: Ferrite

Max temperature: 250 °C

Quality grade: 26/22, 28/16, 26/24, 28/26, C1,C5,C8,C10

Tolerance for D: + 0.5 / - 0.6 mm

Tolerance for H: + 0.3 / - 0.2 mm

Magnetisation: Axial Or radial

Type: Isotropic / anisotropic

Holding force: 10 Newton ~ approx. 1 kg.

Ceramic magnet grades are often categorized into different grades based on their magnetic properties. The most common grading system for ferrite magnets includes C grades, which indicate the magnetic properties of the magnet. Here's an overview of some common C grades for ferrite magnets:

C1 Grade: This is the lowest grade and typically has the weakest magnetic properties among the C grades.

C5 Grade: This is a common grade for ferrite magnets, offering moderate magnetic strength suitable for various applications.

C8 Grade: This grade represents magnets with relatively high magnetic strength. C8 grade ferrite magnets are used in applications where stronger magnetic fields are required.

C10 Grade: This is one of the highest grades available for ferrite magnets, offering very strong magnetic properties.

Their cheap price, together with their high heat and corrosion resistance, makes them perfect in many fields and applications, such as industrial equipment, gadgets, bricolage, automotive, holders, fixtures, sensors and many more!

These magnets can resist at a maximum temperature of 250 °C. If you need a higher temperature resistance contact us.

Please note: Ferrite magnets are fragile and should be handled with care. Although they have a high coercitivity value (which means they do not demagnetize easily), you should avoid placing them in direct contact with more powerful magnets.

Here are some tips for using magnets:

1.Store magnets away from magnetic-sensitive objects, like computer monitors, watches, and magnetic cards.

2.Handle magnets carefully and avoid dropping them, as they can crack or break easily.

3.When assembling magnets, remove them one by one to avoid damage from the attraction between them.

4.Be careful when using strong magnets, like NdFeB magnets, to avoid getting your hands or other body parts caught between them.

Attract and repel

Magnets have north and south poles, and opposite poles attract each other, while like poles repel each other. For example, you can use magnets to pick up paper clips.

Clean up

Use a magnet to collect ferrous objects like nails and screws from a bonfire.

Separate metals

Magnets can be used to separate magnetic metals, like iron, cobalt, and nickel, from non-magnetic metals, like aluminum.

Detect repairs

Use a magnet to inspect a car chassis and detect areas that have been repaired with fiberglass or plastic putty.

Remove metal foreign bodies

Magnets can be used to remove metal objects from food manufacturing processes.

Magnetic levitation

Magnets can be used to suspend, guide, and propel vehicles, like trains, using electromagnetic force.

Cable connections

Some cable connections use magnets as a fail-safe device. For example, the power cords of some laptops are magnetic to prevent damage to the port if the cord is tripped over.

The history of ceramic magnets, also known as ferrite magnets, dates back to the early 20th century.In the 1950s, researchers began experimenting with ferrite materials to create permanent magnets. These efforts led to the development of ceramic magnets, which were initially used in various electronic applications.By the 1960s, ceramic magnets had entered mass production and became commercially available. Their low cost, combined with decent magnetic properties, made them popular for a wide range of applications.ver the decades, advancements in manufacturing techniques have improved the magnetic properties and reduced production costs of ceramic magnets. These advancements have further expanded their applications in industries such as automotive, electronics, and household appliances. Till now, Ceramic magnets are widely used in various applications, including electric motors, speakers, magnetic separators, MRI machines, and magnetic therapy devices, among others.

Key points to consider when selecting a ceramic magnet grade:

Grade Number:

The higher the number following the "Y" designation, the stronger the magnet.

Application Needs:

Assess the necessary magnetic force for your application to choose the appropriate grade.

Temperature Considerations:

Ceramic magnets can be affected by extreme temperatures, so ensure the chosen grade is suitable for your operating environment.

Cost-Performance Balance:

"Y30" is often a good starting point as it offers a good balance of strength and affordability.
