Neodymium magnets are the strongest permanent magnets you can buy. They are made from an alloy of neodymium, iron and boron (NdFeB) and offer a high holding force relative to their size. At Magnetenspecialist you will find them in every common shape, from a Ø2 mm disc for model making to powerful discs and blocks for industry, in grades N35 to N52.

Which shape suits your application?

Besides the standard NiCuNi coating, we offer epoxy magnets for humid environments, self-adhesive magnets that stick without drilling, and plastic-coated and rubber-coated magnets that prevent scratches. Looking for a magnet you can screw in place with maximum holding force? Take a look at our pot magnets: a neodymium magnet in a steel cup.

How do you choose the right neodymium magnet?

• Holding force: listed with every product. Allow a generous margin, because a rough, painted or thin surface reduces the holding force. Read how holding force is determined.
• Grade: N35 to N52. For the same size, a higher number is stronger. What do N35, N42, N48 and N52 mean?
• Coating: NiCuNi for dry indoor use, epoxy or a casing for humid conditions. Which coating should you choose?
• Temperature: standard neodymium magnets are suitable up to 80 °C.

Frequently asked questions

How strong is a neodymium magnet?

That depends on the size and grade. A small disc holds a few dozen grams, while large discs and blocks hold dozens of kilos. The holding force is listed with every product.

Do neodymium magnets lose their strength?

Hardly, in normal use. A magnet can permanently lose strength if it exceeds its maximum temperature, or if the coating is damaged and the magnet starts to rust.

Can neodymium magnets rust?

The material itself rusts quickly, which is why every magnet has a coating. For humid or outdoor use, choose epoxy or a plastic or rubber casing.

Are neodymium magnets safe?

Magnets are not toys and should be kept out of reach of children. Keep them away from pacemakers, electronics and bank cards. Larger magnets can snap together or onto metal with force; keep your fingers clear.

When will my order be shipped?
