Bonded Neodymium Iron Boron Magnets

The bonded Neodymium Iron Boron materials are typically anisotropic. They can be made isotropic, and are manufactured using “binders,” such as epoxy resins or nylon to hold the powder in place, rather than “sintering” the alloy. Energy products of the bonded magnet range from 5 MGOe to 10 MGOe. Two basic processes are used:

Compression Molding Binders are epoxy resins, and energy products of 10 MGOe are achievable. Moderately complex shapes can be achieved.

Injection Molding Binders are generally nylon, but epoxy resins may also be used. Energy products are lower than compression molding; however, more complex shapes can be achieved without final processing, which makes it cost effective for low to medium performance applications which are cost sensitive.

The bonded Neodymium Iron Boron magnet may be used without surface treatment; however, coating is recommended. Generally, spray coatings are used, such has phenolic or epoxy coating.

A word of caution:
Do NOT use Neodymium Iron Boron magnets under the following conditions:

In an acidic, alkaline, or organic solvent (unless you are going to hermetically seal the magnet inside a can)
In water or oil (unless hermetically sealed, or you are prepared to accept a limited life)
In an electrically conductive liquid, such as electrolyte containing water
In a hydrogen-containing atmosphere, especially at elevated temperatures. Hydrogenation, a process where the Hydrogen molecule will react with the NdFeB, will occur, causing the magnet to rapidly deteriorate
Environments containing corrosive gasses, such as Cl, NH3, Nox, etc.
In the path of radioactive rays
