There are 2 magnet families that consumers either hobbyists or industry will most often run into: Rare Earth Magnets & Non Rare Earth Magnets, The rare earth magnet family is derived from what is called rare earth which is an ore mined mostly in China, from which both Neodymium & Samarium are extracted. These 2 elements listed as lanthanides on the periodic table are the namesakes of the 2 most powerful permanent (can’t turn them on and off like electromagnets) magnets on the planet.

Neodymium is the strongest with Samarium cobalt is a very close 2nd place in terms of strength. These magnets however, are not suitable in all situations. Neodymium is not suitable when the magnets are to be out in the weather as they tend to corrode (use Samarium). Samarium is also the go to product when the ambient temperature is greater than 175 0 F. There are some alloys that allow for a higher operating temperature with the neodymium available at HS Magnetics & Magnets For Sale. Just call and we will fill you in.

The other family is the non-rare earth family which pretty much consists of all of the rest. Which are Ceramic Magnets and AlNiCo magnets . Ceramic Magnets are the magnets you probably grew up with as a child. They are not extremely strong but sufficient for most hobbies. You may use a neodymium magnet for refrigerator magnets but use one about 1/3 the size of ceramic magnets. AlNiCo magnets are typically used in industrial settings based on their unique characteristics.
