What materials can be used to produce magnets?

Ferrite magnets – the most classic, but are they the best?

Ferrite magnets were until recently the most popular models of all. most often made of barium ferrite, they are characterized by high corrosion resistance and low price. however, they are quite brittle, and the attraction force sometimes does not match other models. despite this, they are still used in electric motors, various types of holders, and speakers.

Neodymium materials – the strongest type of all

The ability to attract really large weights is the hallmark of neodymium magnets. made of a compound of neodymium, iron, and boron, they are not as corrosion-resistant, so they are covered with a special additional layer that does not affect their attraction. they are used in many sectors from electronics to mechanics, and are also used in underwater searches.

Alnico magnets – very resistant, but require caution

Made of aluminum, nickel, and cobalt, these types of products have the greatest natural resistance to corrosion and high temperatures. unfortunately, they are also highly susceptible to demagnetization, so they should be used cautiously. they are most often found in measuring devices, sometimes in engines and generators, anywhere where strength is needed at certain temperatures.

Samarium-cobalt magnets – useful in specialized use

Like alnico, samarium-cobalt magnets are highly resistant to temperature and rust. however, they are made of samarium and cobalt. this alloy also has some resistance to demagnetization. it is used in the production of prostheses and medical implants, as well as in mechanical bearings and sensors.
each magnet has different properties and characteristics. thanks to such a wide variety, everyone can easily use them for their own needs.
