| 铝镍钴 |
 Alnico magnets, composed of primarily
aluminum, nickel, and cobalt, were developed in
the 1940's. This class of magnet remains a
preferred material because of it's excellent
temperature stability, high magnetic flux density,
and resistance to corrosion. Alnico magnets are
manufactured through a casting or sintering
process. The casting process allows for the magnet
to be manufactured into intricate and complex
shapes, which are not possible with other magnetic
materials. |

 Samarium
Cobalt (SmCo) magnets, of the Rare Earth class,
have been available since the early 1970's. These
magnets possess very high magnetic properties,
excellent thermal stability, while remaining
resistant to corrosion. These characteristics make
SmCo magnets ideal for applications requiring a
resistance to wide-ranging temperatures and
environments.
SmCo magnets are manufactured
by sintering or compression bonding. They are
anisotropic and can only be magnetized in the
direction of orientation. In general, magnetizing
fields of approximately 30 to 45KOe are required
to saturate SmCo magnets. |
