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 sinter process. The casting process allows for the magnet to be manufactured into intricate and complex shapes, which are not possible with other magnetic materials.
Ningbo Tongchuang Strong Magnet Material Co.,Ltd is an original factory specializing in Neodymium magnets, and also manufacturing and marketing
other permanent magnets, such as Sm-Co, Al-Ni-Co, hard ferrite and rubber magnets.

For over 50 years an acknowledged leader in the field of permanent magnets, Arnold continues its tradition of superior quality and value with the full line of Alnico products.
One of the oldest members of our magnet family, Alnico remains the workhorse of the permanent magnet industry and can be relied upon to deliver impressive flux density at an economical price. Alnico also boasts the lowest temperature coefficient of any commercial magnet material (.02% per degree centigrade) allowing for excellent stability over a wide temperature range.
Alnico has experienced renewed interest in recent years in such temperature-sensitive applications as hall-effect and MR-based automotive and electronic sensors, in addition to the traditional magnetron, TWT amplifiers, actuators, motors and instruments applications that have long relied upon Alnico.

Toshiba pioneered the development of Cobalt (Co)-based amorphous (non-crystalline) magnetic alloys for electronic applications. Toshiba offers amorphous magnetic cores for noise suppression, mag-amps, snubbers and pulse transformers. Key applications for these amorphous cores include switching power supplies, noise sensitive equipment, medical instruments and telecommunications.
Improvements in magnetic properties have resulted from Toshiba's commitment to research and development. Toshiba continues its R&D programs to further improve the properties of the amorphous alloys and the magnetic components made from them.

Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors.
|
|
Hard ferrite (ceramic) magnets were developed in the 1960's as a low cost alternative to metallic magnets. Even though they exhibit low energy (compared with other permanent magnet materials) and are relatively brittle and hard, ferrite magnets have won wide acceptance due to their good resistance to demagnetization, excellent corrosion resistance and low price per pound. In fact, measured by weight, ferrite represents more than 75 percent of the world magnet consumption. It is the first choice for most types of DC motors, magnetic separators, magnetic resonance imaging and automotive sensors.
To better serve our customers of hard ferrite magnets, Arnold sources material from qualified manufacturers throughout the world.

Spanning the range of applications from advertising specialties (signs and labels) to micro-motor magnets, biomedical, surgical drapes, car ski-rack hold-down systems and automotive sound deadening, flexible bonded magnets serve us in a multitude of product types and markets. Ferrite flexible magnets have existed as a product for over 25 years. More recently, rare earth flexible bonded material has become available.
Three processes are used for manufacturing:
- an extrusion process which is widely used for "profile extrusion" (magnets with irregular cross-section),
- calendering or rolling of pelletized compound between two rollers to form a continuous sheet, and
- a combination extruder/calender process.
Each process has advantages and limitations.

Ferrite magnets are sintered permanent magnets composed of Barium or Strontium Ferrite. This class of magnets, aside from good resistance to demagnetization, has the popular advantage of low cost.
Advantages:
1 Because they are ceramic, Ferrite magnets have a tendency to break or chip and require careful handling during assembly.
2 The magnetic flux temperature coefficient is -0.18%/„aC, much larger than for rare earth magnets or alnico magnets, so temperature stability must be taken into account.
3 Coercive force decreases at a rate of 0.5%/„aC when the temperature decreases, and problems many occur due to low temperature demagnetization. It is vital that the magnet¡¦s operating point be higher than the knee point on its demagnetization curve.
4 Low cost No surface treatments.
Application Fields:
Motors, loudspeakers, medical equipments, instruments, sensors, toys, crafts, and so on.
Detailed information:
The properties: We could produce the Ferrite magnets with many grades from the isotropic Y10T to antistrophic Y35, for the detailed information, please kindly check the properties chart. We could adjust our composition to meet our customer¡¦s requirement.
The magnetization: Ferrite magnets can be produced isotropically or anisotropically. Isotropic grades are not oriented and can be magnetized in any direction, although some degree of greater magnetic strength will be found in the pressing dimension. Anisotropic grades are oriented in the manufacturing direction, and must be magnetized in the direction of orientation.

Tolerances of hard ferrite magnets
Bakker Magnetics can guarantee tolerances applicable to unfinished magnets
(DIN 17410). Customers can obtain the desired tolerances on request. If the
customer so wishes, we can deviate from our standard tolerances.

One of the more important developments in magnetic materials, polymer bonded magnets, have opened a new world of application opportunities. The processing temperatures employed to blend and mold the material mixture is low enough to allow many different magnet powders to be used alone or in combination in the polymer binder to achieve an unprecedented range of properties.
Another benefit of the injection molding process is that magnet material can be directly molded into, onto, or against other assembly components eliminating subsequent assembly steps. This is called insert injection molding.
Injection molded magnets can be of very simple shapes or very complex. All or only part of the device may be magnetized. It is sometimes cost advantageous to make an entire part out of the magnet material and just magnetize the portion requiring magnetic output.
