Neodymium magnets and assemblies are used in almost 80% of today’s applications because of their extraordinary performance and availability. They are the strongest permanent magnets man can make so far. So when you are considering using a permanent magnet in your application, put neodymium at the top of your list.
Ceramic Magnets, formally named Hard Ferrite magnets, are made in the same way as ceramic plates are made. Ceramic magnets are the most economical magnets, so even if they are not as strong as neodymium and SmCo magnets but still find lots of applications in the industry and at home. such as fridge magnets, office magnets, magnet education, and crafting. It also has more applications in the industry than the other magnets since its low cost, such as toys, motors, relays, magnetic holding, magnetic separation, and filtration. These magnets are also very good options for magnetic therapy even though more and more people are beginning to use neodymium magnets for health purposes. Some other advantages of using ceramic magnets are non-corrosion and high-temperature resistance. The working temperature of this kind of magnet is around 482 degrees Fahrenheit.
Ceramic magnets or Hard Ferrite Magnets are molded and sintered. The mold availability is a big factor to consider when you acquire this type of magnet. Even though you may find limited sizes and shapes in our store Stanford Magnets has many more molds available.
3. SmCo Magnets
Samarium Cobalt magnets, in short, SmCo magnets, are sintered rare earth magnets and majorly contain Samarium and Cobalt elements. It was invented much earlier than Neodymium Magnets (known as NdFeB magnets, or rare earth magnets) and also are strong magnets since they are much stronger than ceramic and AlNico magnets. The powerful Samarium Cobalt magnets are majorly used in the industry when the working temperature is higher than 428 degrees Fahrenheit ( 220 degrees Celsius ) at which neodymium magnets will lose their magnetism. One of the major drawbacks of SmCo magnets is it is more fragile than the neodymium magnet so it is easier to chip or break. SmCo cost is also higher than the neodymium magnets which have similar strength. Because of these issues, SmCo magnets are rarely used by regular consumers for their needs, instead, the major applications of SmCo magnets are industrial applications which include motors, high-temperature assemblies, etc.
SmCo Magnets (Samarium cobalt magnets) have two kinds of families: SmCo5 and Sm2Co17. SmCo5 usually is made of three heavy metals of binary and similar metals and cobalt by the ratio of 1:5 compositions. Sm2Co17 usually is made of two samarium cobalt atoms and 13-17 t atoms.
SmCo magnets (Samarium cobalt magnets) are usually obtained by sintering; sintered SmCo magnets (Samarium cobalt magnets) are brittle and lack ductility. Therefore SmCo Magnets (Samarium cobalt magnets) should be handled with care. SmCo Magnets (Samarium cobalt magnets) have good corrosion resistance, so the surface is usually not processed.

4. AlNiCo Magnets
Aluminum nickel cobalt magnet, in short AlNiCo, can be made by sintering or cast. AlNiCo magnet is very stable and exhibits very good machinability and electrical conductivity. It is much weaker than neodymium and SmCo magnets but can work up to 1000 degrees Fahrenheit (538 degrees Celsius). AlNico magnets are easily demagnetized since the coercive force is relatively low. AlNiCo magnets are majorly used in the industry when stability and high heat are the major concerns, or when conductivity is needed. The applications of this magnet include electric motors, electric guitar pickups, microphones, sensors, relays, and loudspeakers.
Stanford Magnets makes AlNiCo magnets and also inventory these magnets for its customers when they are regularly ordered. Stanford Magnets also has some AlNiCo magnets on the shelf available for purchase.
