    Excellent corrosion resistance

    1. Description of SmCo magnets:
    As part of the rare earth group of permanent magnets, samarium cobalt(SmCo) magnets have very high magnetic properties and temperature properties. Their Curie temperature can be as high as 710 to 880℃, maximum working temperature can be 250 to 350℃, so this kind of magnets have the best magnetic stability. They include rare earth Sm1Co5 and Sm2Co17 and are referred to as 1:5 and 2:17 materials. There’re three different manufacturing processes: sintered SmCo magnet, bonded SmCo magnet, and injection molding SmCo magnet.

    2. Characteristics:
    * SmCo permanent magnet has high magnetic energy product and high coercive force. Its properties are better than Alnico, ferrite permanent magnet. Its max. energy product is up to 239kJ/m3(30MGOe), which is three times of that of Alnico8 permanent magnet, eight times of that of ferrite permanent magnet (Y40). So the permanent magnetic component made from SmCo material is small, light and stable in property. ISO9001 Certificated Customized U Shape SmCo Permanent Magnet
    * The curie temp. of the SmCo permanent magnet is high and its temp. Coefficient is low. So it is suitable for use at 300℃, or even higher temp.
    * SmCo need not to be coated because it is difficult to be eroded and oxidized. The main ingredient of SmCo permanent magnet is metal cobalt, cost of SmCo material is the most expensive of magnet material, so SmCo is recommended only when its performance is a high temperature environment is a concern. Custom Design Sintered SmCo Magnets for Transducers

    3. Magnet shape:
    SmCo permanent magnet can be made in many kinds of shapes like ring, disc, cylinder, arc, block, stick, cuboid, cube, bar, countersunk, segment, trapezoid and other abnormal shape according to customers’ requirement, customized shapes are available.

    4. Application:
    It is widely applied to electro acoustic& telecommunication apparatus, electric motors, measure meters, peg-top, electronic watch, microwave apparatus, magnetic mechanism, sensor and other static or dynamic magnetic routes.
