Ceramic Magnets - Ferrite Magnets Supplier

Supplying various ceramic magnets and ferrite magnets, including discs, blocks, rings, and other sizes.

Ceramic magnet material (Ferrite) is one of the most cost-effective magnetic materials.

It has a fair to good resistance toward corrosion and it can operate in moderate heat.

Ceramic (Ferrite) magnets have low energy product and they are usually used in assemblies containing mild steel.

Ceramic magnets are manufactured using powder technology techniques.

The primary raw material – ferrite – is made by using iron oxide and strontium carbonate.

Ferrite represents more than 75 percent of world magnet consumption (by weight).

It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging, and automotive sensors.

One category of strong magnets that we have in stock is a whole line of ceramic magnets.

Our ceramic magnets are high in demand and are highly versatile.

These have been used in many an industry and with a high success rate.

You can never go wrong with our huge assortment of ceramic magnets.

From inducers, electromagnets and transformers magnets have been used in everything.

We stock both ceramic blocks and rings for whatever projects you need them for.

Many materials have unpaired electron spins, and the majority of these materials are paramagnetic.

When the spins interact with each other in such a way that the spins align spontaneously, the materials are called ferromagnetic (what is often loosely termed as "magnetic").

Due to the way their regular crystalline atomic structure causes their spins to interact, some metals are (Ferro)magnetic when found in their natural states, as ores.

These include iron ore (magnetite or lodestone), cobalt, and nickel, as well as the rare earth metals gadolinium and dysprosium (when at a very low temperature).

Such naturally occurring (Ferro)magnets were used in the first experiments with magnetism.

Technology has since expanded the availability of magnetic materials to include various manmade products, all based, however, on naturally magnetic elements.

Not only do we have a collection of ceramic magnets but we also have a large range of Neodymium Magnets as well.

These magnets are very robust in relation to their size.

Popular with industries and hobbyists.

Neodymium magnets are used in a wide variety of applications.

From hard drives to headphones to loudspeakers these magnets have seen it all.

Ceramic Magnets or ferrite

Ceramic magnets, or ferrite, are made of a sintered composite of powdered iron oxide and barium/strontium carbonate ceramic.

Due to the low cost of the materials and manufacturing methods, inexpensive Ceramic magnets (or nonmagnetized ferromagnetic cores, for use in electronic components such as radio antennas, for example) of various shapes can be easily mass-produced.

The resulting Ceramic magnets are noncorroding, but brittle and must be treated like other ceramics.

Neodymium-iron-boron (NIB)

Neodymium magnets also referred to as neodymium-iron-boron (NdFeB) magnets, have the highest magnetic field strength, but are inferior to samarium cobalt in resistance to oxidation and temperature.

This type of magnet has traditionally been expensive, due to both the cost of raw materials and licensing of the patents involved.

This high cost limited their use to applications where such high strengths from a compact magnet are critical.

The use of protective surface treatments such as gold, nickel, zinc, and tin plating and epoxy resin coating can provide corrosion protection where required.

Beginning in the 1980s, NIB magnets have increasingly become less expensive.

Even tiny neodymium magnets are very powerful and have important safety considerations. At Applied Magnets you will get the best possible price on these Neodymium magnets.

All you have to do is just browse and choose from our huge selection and we will do the rest.

Plus with shopping online you get the modern convenience of buying from your home or place of business.

Nonetheless, our neodymium magnets come in many different shapes and sizes.

From blocks, cubes, spheres, cylinders to arcs and rings;

we here on our website offer it all.

We can supply you with our neodymium magnets better than the other suppliers out there.

Features & Characteristics of Ceramic Magnets

What are the main characteristics of ceramic magnets? Ceramic magnets are medium in magnetic strength and can be used at fairly high temperatures.

They are low cost, making them ideal for applications such as automotive sensors, magnetic separators, craft projects, badge holders, latches, display boards, science projects, toys, games & more.

What grades & shapes are available for ceramic magnets? Grades 5 (most commonly used) through 8 are available in disc, block (rectangle & square), and ring shapes, and can be custom manufactured to meet your specialty requirements.

What are the temperature constraints for ceramic magnets? Ceramic magnets can be used at fairly high temperatures, although their magnetic properties drop with temperature.

At 175°C (350° F), approximately 75% of their room-temperature magnetic properties are retained.

How are magnets rated? Magnets are typically rated by their residual induction, coercive force & maximum energy product.

This refers to the maximum strength that the magnetic material can be magnetized to.

What are some common applications for ceramic magnets? Common applications for ceramic magnets include craft projects, refrigerator magnets, badge holders, latches, display boards, loudspeakers, security systems, motors, generators & alternators, lifting magnets, eddy current devices, brakes, clamps, switches & relays, sweeper magnets, science projects, toys, games, motors, magnetic couplings, POP displays, advertising giveaways, promotional items, novelties & more.

Are there machining constraints for ceramic magnets? Ceramic magnets require special machining techniques and should be machined in an “un-magnetized” state.

We are fully equipped to machine these materials to your specifications, just let us know what you are looking for by sending us a special request.

Are surface treatments required for ceramic magnets? Ceramic magnets do not need to be protected for surface rust.

A thin film of magnet powder on the surface is common.

What are some bonding applications for ceramic magnets? Ceramic magnets are often assembled into products using "superglues" such as Loctite 325 or other epoxies.

Please always ensure that bonding surfaces are clean and dry prior to bonding.

What safety precautions should be taken into consideration when working with ceramic magnets? Ceramic Magnets are hard & brittle, and they can chip or break if dropped or snapped together, so please take special care when handling these magnets!
