Neodymium magnets
Neodymium magnets
These are sintered magnets made by powder metallurgy and consisting mainly of neodymium (Nd), iron (Fe) and boron (B). Having the highest magnetic energy of all existing magnets, these products are notated as NF among our product lines.

* Click here for details of Nd-Fe-B magnets.
 Samarium-cobalt magnets
Samarium-cobalt magnets
These sintered products consist of samarium (Sm) and cobalt (Co). Two kinds of material are available: 1-5 series and 2-17 series.

* Click here for details of Sm-Co magnets.

Ferrite magnets
Ferrite magnets
These sintered ceramics products are based on iron oxide or a similar compound. Although not possessing much magnetic energy, these products offer stable performance and are resistant to rust, thereby achieving high cost performance.

* Click here for details of Ferrite magnets.
 Neodymium plastic magnets
Neodymium plastic magnets
Just like sintered neodymium magnets, these magnets consist mainly of neodymium (Nd), iron (Fe) and boron (B).

* Click here for details of Neodymium plastic magnets.

Al-Ni-Co magnets
Al-Ni-Co magnets
This type of representative magnet has existed since ancient times. These cast magnets combine iron (Fe) with aluminum (Al), nickel (Ni) and cobalt (Co).
