Must collect the motor magnet website.

ALB found that many customers asked for Nd-Fe-B sheets.

Often they would ask, how many mm can you make the thinnest magnet? Also, mobile phones are becoming thinner and thinner now.

The speaker camera of mobile phones is naturally thinner and thinner.

This requires that manufacturers of magnets have certain strengths and experience.

A samarium-cobalt magnet was proofed for a precision electronics factory in the USA before the small edition.

Its thickness is 0.2mm and how thin is 0.2mm? It is equivalent to the thickness of two ordinary A4 paper.

It is very troublesome to produce such thin paper, and the scrap rate is high.

It is suggested that the thickness of A4 paper should be more than 0.4mm.

Not only Nd-Fe-B magnets but also ferrite magnets can be made with a thickness of less than 1 mm.

The ferrite sheet shown below is 0.65.

The specifications of the magnets are F12.5*8.5*0.65.

If you want to customize micro precision magnets, square ultra-thin NdFeB magnets, ultra-thin NdFeB magnets quotation proofing welcome to contact us.

Warm Tip: Because the thickness of the magnet is thin, it is easy to break, so use it with extra care.

thin small magnets

Small Thin Ceramic Magnets

Small Thin Ceramic Disc Magnets are 1/2" (.50) across and only 1/8" thick (half the thickness of the Small Magnets) with about the same magnetic pull. These are Grade 5 Magnets. Strong Hold.

Made in the USA.

Even though these Ceramic Magnets are thinner, they have almost the same pull as the ones that are 3/16" thick. These are a Grade 5 Magnet. Strong Hold. Round ceramic magnets can't be cut. They do require adhesive to attach. We recommend E6000 for a strong bond. Small Thin Magnets are sold in packs of 1000.

Hard Ferrite ceramic magnets were developed in the ’60s and today comprise 75% of world magnetic consumption.

Despite their relatively low magnetic values, they are the most popular magnet on the market due to their ready availability and relatively low cost.

The raw material from which ferrite magnets are produced is Strontium Ferrite powder (mainly ScO.6Fe203) which is formed in a press while subjected to an electric field.

This process allows the direction of the magnetic field to be determined during the production of the magnet.

Ferrite magnets main qualities: ferrite High coercivity (= high resistance of the magnet to demagnetization).

Highly stable under difficult environmental conditions with no need for a coating to protect the magnet.

High resistance to oxidation.

Durability – the magnet is stable and constant.

Ferrite magnets popular uses: automotive industry, electric motors (DC, brushless, and others), magnetic separators (mainly plates), home appliances, and more.

ALBspecializes in the production of Hard Ferrite (anisotropic) using a wet pressing process.

Cutting and grinding of the magnets are performed with an electroplated diamond grinding wheel.

Craft and Hobby Disc Hard Ferrite Magnets

Ceramic Magnets are strong, can’t be cut, and are perfect for Glass Gems, Mirrors, and many other magnetic crafts.

They have enough strength to hold additional items (photos, papers, etc) to any magnetic surface, even when attached to craft items.

Whether you choose thin or thick ceramic magnets they have about the same stronghold (magnetic pull).

The strongest is the large ceramic magnet which measures nearly an inch across.

If you need something stronger, try our Neodymium Magnets.

Even though they are smaller than most of our ceramic magnetic discs, they are stronger!

Our Magnets Are Everywhere!

In our day-to-day lives, we rarely have the opportunity to see rare earth magnets with our own eyes, but because of the strength of their magnetic force, they are the ideal magnet for size reduction and energy conservation and are actually in use all around us.

Here, we would like to introduce various devices that are indispensable in our lives and that use rare earth magnets.

Thin, large-screen TVs have compact, high sound quality speakers mounted in them.

Rare earth magnets are used in these speakers and contribute to giving these speakers smaller sizes and higher sound quality.

Rare earth magnets are used in DVD recorders (players) and DVD writing heads (optic pickups) to accurately read the video and audio signals.

Rare earth magnets are used also in the voice coil motors (VCM) that drive the heads that read and write the video and audio signals in the hard disk drives mounted in recorders with hard disk drives.

Air conditioners control the room temperature by compressing and expanding gas that is serving as a medium for heat.

Rare earth magnets are used in the compressor motors that compress this gas.

Using rare earth magnets increases the energy saving of air conditioners.

Heat pump type water heaters (Eco Cute) generate heat by compressing and expanding the same gas as air conditioners (*there are also many hot water heaters that use CO2) and use that heat to heat water.

Rare earth magnets are used in the compressor motors for compressing the gas.

Refrigerators cool gas by compressing and expanding the same gas as air conditioners (*there are also many refrigerators that use CO2) and use that cooled gas to refrigerate and to freeze.

Rare earth magnets are used in the compressor motors for compressing the gas.
