A neodymium magnet (also known as NdFeB, NIB or Neo magnet), the most widely used type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron and boron to form the Nd2Fe14B tetragonal crystalline structure. Neodymium magnets are the strongest type of permanent magnet commercially available.

The AlNiCo magnets feature excellent temperature stability, high residual induction, and relatively high energies characterize Alnico materials, composed primarily of alloys of Aluminum, Nickel, and Cobalt. They are manufactured through either a casting or sintering process. Cast magnets may be manufactured in complex shapes.

Samarium Cobalt (SmCo) magnets offer designers a tremendous combination of extremely high magnetic properties, outstanding thermal stability and excellent corrosion resistance. As part of the rare earth group of permanent magnets, Samarium Cobalt (SmCo) magnets typically fall into two families of materials. They include rare earth SmCo5 and Sm2Co17, and are commonly referred to as 1:5 and 2:17 materials.

Iron chromium cobalt permanent magnets can be magnetized by plane octapole, multi-pole magnetized by plane, and has the advantage of being machined. It is especially suitable for small and thin permanent magnet components with complicated shapes and sizes. Can be used in telephones, tachometers, micro motors, micro relays, speakers, etc.
