Compressed non-bonded magnet - possible?

In summary, the conversation discusses the possibility of creating a compressed "non-bonded" magnet by compressing magnet powder without a binder and sealing it in a can-like object. The question is raised of who is capable of manufacturing such a magnet. The suggestion is made to use sintered magnets instead, and it is noted that they can also be over-molded for specific applications.

Compressed "non-bonded" magnet - possible?

Dear everyone
As opposed to a bonded magnet being magnet powder "glued" together with e.g. epoxy and which is incapsulated as to prevent corrosion - does anyone know if one can instead compress magnet powder without a binder directly in a can-like object and seal it of hermetically afterwards? And if so, who is capable of manufacturing such an incapsulated and "non-bonded" magnet?
Thank you millions in advance for your time and consideration.

Ceramic magnets are fairly non-reactive, but I've seen them over-molded with Teflon for an ultrapure application. Of course, you have to pay for an injection mold.

Good luck,

Aside from bonded magnets, there are also sintered magnets, would those suit your purposes?
 

1. What is a compressed non-bonded magnet?

A compressed non-bonded magnet is a type of magnet that is created by pressing together magnetic particles without any bonding material. This results in a magnet with higher magnetic strength and energy compared to traditional bonded magnets.

2. How is a compressed non-bonded magnet different from a regular magnet?

A compressed non-bonded magnet is different from a regular magnet because it does not contain any bonding material such as resin or glue. This allows the magnetic particles to be in closer proximity, resulting in a stronger magnetic field.

3. What are the potential applications of compressed non-bonded magnets?

Compressed non-bonded magnets have a wide range of potential applications. They can be used in motors, generators, sensors, and other electronic devices where high magnetic strength and energy are required.

4. How is a compressed non-bonded magnet made?

To create a compressed non-bonded magnet, magnetic particles are first mixed together and then compressed under high pressure. This process aligns the particles in a specific orientation, resulting in a stronger magnetic field.

5. Are there any disadvantages to using compressed non-bonded magnets?

One potential disadvantage of compressed non-bonded magnets is their higher cost compared to traditional bonded magnets. Additionally, the manufacturing process for these magnets is more complex and requires specialized equipment, making them less accessible for some applications.
