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.
Click on the above magnets or download the free specification sheet of the desired magnet grade.
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. Download our free magnet coating selection table.
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.
More than just a magnet
The possibilities with magnet technology are endless, which is why it can quickly become confusing. Goudsmit has more than 60 years of experience in the world of magnetism and is happy to help you with advice and a range of services:
