Permanent neodymium magnets
Neodymium-iron-boron (NdFeB) magnets offer the highest energy product of all magnet materials. They are available in a wide range of shapes, sizes, direction of magnetization, coatings and grades. You can find NdFeB magnets in many applications, such as electric motors, sensors, switches and loudspeakers.
Goudsmit offers a wide range of services with regards to the design and selection of the appropriate magnet for your specific application. For instance, we apply magnet calculations and FEM simulations to quickly identify the best magnet for your product. In addition, we have all the necessary processes in place to supply the automotive and aerospace industries, including IATF16949 and AS9120 certifications.

NdFeB magnet grades
Neodymium magnets are available in different grades, from N35 to N55SH. Each with unique magnetic properties, such as Br energy product, HcJ resistance to demagnetization, and temperature resistance.

Our technical specialists are ready to help you choose the right magnet for your specific application. Please feel free to contact us for advice or more information about our products and services.
The right coating for protection and manufacturability
Although neodymium is magnetically the strongest alloy, it also has less favorable properties. Sensitivity to corrosion, low temperature resistance, poor adhesive properties, and mechanical brittleness partly determine whether this type of magnet can be used in your product. A suitable magnetic coating can offer a solution for this.
We have various options for coating NdFeB magnets, such as:
- Ni-Cu-Ni (standard): the most commonly used coating to protect against corrosion in normal applications.
- Ni-Cu-Epoxy: susceptible to scratching, but has very good adhesive properties with high breakaway force.
- HDPE: thicker coating that protects against UV radiation.
- Parylene: ultra-thin, pinhole-free polymer coating with superior abrasion resistance.
- Ni-Au: thin 24 carat gold layer on top of nickel coating. Used for medical applications.
- Plastic: super durable and highly corrosion resistant. It protects magnets from breaking on impact and prevents corrosion by creating a watertight barrier between the magnet and moisture.
- And many more.
It can be difficult to select the best coating due to the many factors that affect a magnet’s durability and performance. You can always contact our magnet experts with questions or for help choosing the right coating for your project.
