    Bonded Samarium Cobalt is the highest grade of material that can either be made by using nylon 12 or compression molded using epoxy. It was developed by Seiko Epson Corporation and can be made radial up to 15 Mgoe, cross field up to 17 Mgoe, and axially by similar method for 15 Mgoe. Typically used in high quality stepping motors, this material has been in the market place for over 20 years and MPCO has yet to have a reject of any kind.

    Samarium Cobalt Compression Bonded Magnets are one of the newest types of magnetic materials and are made by compressing an epoxy coated SmCo magnet powder into a final shape and then heat treating it. The result is a high density material which produces a higher magnetic output than by injection molding. Although compression molding provides greater flexibility in geometry shape and size, they do not provide the range of complex geometries which can be achieved by injection molding. The following tables list common grades, however custom grades can be made depending on customers’ requirements.

    Anisotropic Isotropic Bond SmCo Permanent Magnets

    Anisotropic bonded NdFeB permanent magnets have wide potential applications in the areas such as brushless DC motors, spindle motors, and stepping motors due to their excellent processing property and high magnetic properties. Anisotropic NdFeB bonded magnets prepared by hydrogen-disproportionation–desorption-recombination (HDDR) process have large energy product at room temperature. However, they are not stable at ∼100°C, which is the working temperature of many electric motors. In order to improve their thermal stability, we developed bonded NdFeB/SmCo magnets and investigated the effects of powder particle size and SmCo content on their magnetic properties. We proposed a model to clarify the filling effect of the powder, which played a key role in the enhanced (BH)max when reducing the SmCo particle size. As for the SmCo content, the bonded magnets showed improved (BH)max at 100°C-150°C and thermal stability with the increase of SmCo content. And through adjusting the SmCo content, the remanence temperature coefficient and coercivity temperature coefficient from 25-150°C were able to be regulated in the range of -0.14%/°C to -0.04%/°C and -0.51%/°C to -0.14%/°C, respectively. This work provides a design strategy and a facile route to improve the magnetic properties and thermal stability of the bonded magnets.

    MPCO offers both compression bonded 1:5, and 2:17 SmCo magnets. They have lower energy products than sintered SmCo – currently in the range of 4.0 to 10.0 MGOe.
    Polymer samarium cobalt magnets with SmCo magnetic powder mixed with polymer materials, compressing through the shaped die, various shapes of high dimensional accuracy can be produced, requiring no further finish machining. Due to excellent corrosion resistance, coating is not required.

    MPCO has over 20 years experience on manufacturing and technology on the polymer samarium cobalt magnets. With its own molding workshop, the factory can accomplish entire production process in-house from molding design, manufacturing and maintenance. The plant has obtained automatic production with rigorous Japanese-type management and precise equipments imported. Bonded Samarium Cobalt Magnets
