We are professional manufacturer and exporter of China
Magnet.
Permanent magnets are used in the following major
area: acoustic transducers, motors and generators, magneto
mechanical devices, and magnetic field and imaging systems. You
will find permanent magnets in many products, such as televisions,
telephones, computers, audio systems and
automobiles.
The permanent magnet family
consists, in general terms, of rare earth permanent magnets and
non-rare earth magnets. Rare earth magnets include Sm-Co
(Samarium-Cobalt) magnets and Nd-Fe-B (Neodymium-Iron-Boron)
magnets. The non-rare earth magnets include Alnico
(Aluminum-Nickel-Cobalt) magnets and Ceramic (Strontium and Barium
Ferrite) magnets.
Although non-rare earth
magnets are used in the majority of these applications due to their
economic cost, rare earth permanent magnets have many
distinguishing characteristics, such as a large Maximum Energy
Product, (one performance index for permanent magnets).
Dozens of magnetic materials which contain rare earth have been
developed recently. Two major families of rare earth permanent
magnets, Sm-Co magnets and Nd-Fe-B magnets, have been widely used
in a variety of applications. Each family has its own advantages
and disadvantages.
