Surface Treatment
Although plastic bonded ndfeb magnets have a good corrosion resistance, we still advise to make a coating for them so that the durability is optimal. Epoxy is the most commonly used plating for bonded ndfeb magnet. You can find more information from our Magnet Coating Page.
Magnetization Direction
Due to the isotropy, the plastic bonded magnets can be magnetized in different directions. More complex directions are easy to realize. You can find more information from our Magnetization Direction Page.
Tolerance
There is no necessary for secondary operation in the production process. So the consistency of magnetic performance is good and tolerances are very tight.
Advantages
Relatively Powerful Magnetic force
Lower Temperature Resistance
Excellent Oxidation Resistance
Good Chemical Resistance
Extreme resistance to demagnetization
Multi-pole magnetization direction
Tight Tolerances Possible
Good Mechanical Strength
