Permanent Magnet

Neodymium Magnet (NdFeB)
Neodymium Magnets (NdFeB) are one of the strongest permanent magnets in the world and are widely used in large industries. The constituent elements of this magnet are the rare elements neodymium (Nd), iron (Fe) and boron (B), which has one of the highest permanent magnetic intensities.
Cobalt Samarium Magnet (SmCo)
Cobalt Samarium Magnets (Smco) are about as strong as neodymium magnets, and their main advantage is the ability to withstand high temperatures (up to 350 degrees Celsius). Unlike neodymium magnets, these magnets due to their corrosion resistance do not need to be coated.

Alnico Magnet
Alnico Magnets are the third largest permanent magnet in terms of magnetic field strength. The main components of these magnets are aluminum (Al), nickel (Ni) and cobalt (Co). One of the advantages of this type of magnet is its ability to withstand temperatures up to 500 degrees Celsius.

Ferrite Magnet
Ferrite or Ceramic magnets are in the lowest category of industrial magnets in terms of magnetic field strength among other magnets made from casting methods. At the same time, these magnets have a higher degree of permeability (Gradient) than other permanent magnets. The constituent elements of this magnet are iron oxide, strontium oxide, etc.
