Bonded Neodymium Magnet Surface Coating and Operating Temperature

What is the black substance on the exterior of the bonded neodymium magnet? What type of coating is it? Additionally, which protective layers can be applied? What is the maximum operating temperature for bonded neodymium magnets? Today, we will address these questions.

What is the black coating that covers the surface of a neodymium magnet?

It is a black cyclic hydrogen resin. Additionally, processes such as acrylic resin electrophoresis, epoxy resin spraying, Teflon spraying, polystyrene deposition, and direct air impregnation can be performed for coating and surface treatment. Corrosion resistance, solvent resistance, friction resistance, and other specifications can be selected and combined based on the environmental requirements of use.

Maximum Operating Temperature of Bonded Neodymium Magnets

The maximum operating temperature for bonded iron-boron magnets is approximately 120 to 150°C, depending on the specific grade.

Curie Temperature for Bonding Neodymium Magnets

Curie temperature of bonded NdFeB magnets ranges from 310 to 340 °C.

What shapes can your bonded neodymium magnets take?

Bonded neodymium magnets are primarily available in ring shapes and are multipole magnetized. They can also be manufactured in various forms, including square, arc, and other shapes.

Bonded ferro-boron magnets are one of our key strengths. We can provide fully pressed bonded iron masonry magnets upon request.
