In fact, a strong neodymium can demagnetize a ceramic magnet (see it happen in our video above). The same cannot be said for ceramic magnets. It takes a huge external magnetic field to demagnetize a neodymium magnet. Neo pull force 16.4 lb.Ĭoercive force - Neodymium magnets have a much higher coercive force, that is, a higher resistance to demagnetization. The same size neodymium magnet, our DCH2, has a pull force of 16 lb.that's quite a difference! Ceramic (left) vs neodymium (right). When directly attracting to a steel plate, it has a pull force between 2-3 lb. In the photo below, we have a 0.7" dia x 0.2" thick C8 ceramic magnet. Let's look at a practical example of this. For example, taking the strongest grade of each material, C8 vs N52, we can assume that N52 is 6.5 times stronger than C8, based on the BHmax spec. However, using the BHmax number, we can infer the difference in strength between the two materials. Plating - What the magnet can be coated/plated with, to avoid corrosion.īHmax - This is a single number that describes the strength of the material, but practical pull force is also determined by the size and shape of the magnet.

Curie Temp - The temperature at which a magnet loses all of its magnetic properties.

Above the max operating temp, magnets will start to lose their strength.

MaxOpTemp - Also known as maximum service temperature, is the temperature at which the magnet may be exposed to continuously with no significant long-range instability or structural changes.

The higher the number, the more resistance to demagnetization.

Coercive Force - Resistance to demagnetization.

It also happens to be the "N" number in neodymium magnet grades (N35, N42, N52, etc).

BHmax - A single number that describes the strength of a magnet.

What do each of these mean (in layman's terms please)? Nickel, Black Nickel, Silver, Gold, Epoxy, Plastic, Rubber, Zinc Rather than list out all of the available "grades", we'll provide a range of grades and their specs. Let's compare the main specs of ceramic magnets and sintered neodymium magnets. Interested in replacing a ceramic magnet with a neodymium magnet? Email our engineers, we'd be happy to discuss the potential options and advantages. In this article, we'll compare the two materials, talk about the pros and cons of each, and ultimately show how neodymium magnets are superior (we might be a little biased). In our opinion, the two most common types are ceramic and sintered neodymium. We specialize in and supply sintered neodymium magnets. In the world of permanent magnets, there are several different materials - ceramic (ferrite), AlNiCo, Samarium Cobalt (SmCo), bonded neodymium, and sintered neodymium. We even have matching and complimentary keyrings for you to choose from.Ceramic magnets (left) vs neodymium magnets (right).
