    Samarium cobalt magnet, also known as SmCo magnet, is another type of permanent magnets. A big advantage of SmCo magnets is that they can operate at temperatures up to 300 degrees Centigrade. SmCo magnets are widely used in applications in which high operating temperature and high corrosion and oxidation resistance are crucial. Orientation Magnetized Through Thickness Sintering SmCo Segment Magnets

    The alloys are typically machined in the unmagnetized state. Samarium–cobalt should be ground using a wet grinding process (water-based coolants) and a diamond grinding wheel. The same type of process is required if drilling holes or other features that are confined. The grinding waste produced must not be allowed to completely dry as samarium–cobalt has a low ignition point. A small spark, such as that produced with static electricity, can easily commence combustion. The resulting fire produced can be extremely hot and difficult to control.

    The reduction/melt method and reduction/diffusion method are used to manufacture samarium–cobalt magnets. The reduction/melt method will be described since it is used for both SmCo5 and Sm2Co17 production. The raw materials are melted in an induction furnace filled with argon gas. The mixture is cast into a mold and cooled with water to form an ingot. The ingot is pulverized and the particles are further milled to further reduce the particle size. The resulting powder is pressed in a die of desired shape, in a magnetic field to orient the magnetic field of the particles. Sintering is applied at a temperature of 1100˚C–1250˚C, followed by solution treatment at 1100˚C–1200˚C and tempering is finally performed on the magnet at about 700˚C–900˚C. It then is ground and further magnetized to increase its magnetic properties. The finished product is tested, inspected and packed.

    Gluing Magnets
    Several factors must be considered to assure the effective performance of the magnet, the adhesive and the resulting bond. These include the chemical and physical properties of the magnets and the surfaces to which they are affixed. Detailed coverage of all these factors, along with some adhesives to try, is covered in our white paper Gluing Magnets.

    Permanent Magnets in Different Shapes and Various Coatings
    Samarium-Cobalt magnets have particularly high coercivities with simultaneous high saturation polarization and excellent temperature and corrosion stability. Benefits:
    Suitable for high temperature applications (depending on alloy up to max. 350 °C)
    High corrosion resistance against aggressive media
    Usually no coating necessary
    Low decrease of magnetic properties with increasing temperature due to high Curie temperature

    Heavy duty super powered Samarium Cobalt magnet. Samarium Cobalt although not quite as strong as neodymium has a better corrosion resistance and a much higher working temperature & is still in the class of the permanent supermagnet. Samarium Cobalt is also a rare earth magnet, like neodymium and can be used for much the same type of applications like scientific applications tool hangers decorations towel hangers knife holders refrigerator magnets scrap books recoup storage general description these cube magnets are made for holding stuff & that is what they do. High Curie Temperature Custom Arc Sector Sintered Sm2Co17 Magnet

    The main application for arc segment magnets is in motors or generators, either for rotors or stators. We can supply Ferrite, Neodymium Iron Boron and Samarium Cobalt arc segments. Which material is used depends on the required torque, maximum operating temperature, environmental conditions and cost. High Magnetic Properties Bespoke Customized Sintered Smco Arc Magnet

    A Samarium Cobalt magnet can withstand higher temperatures than a Neodymium magnet. The maximum operating temperatures for Samarium Cobalt magnets are between 250 and 550 °C; Curie temperatures range from 700 to 800 °C. Additionally, a Samarium Cobalt magnet is less subject to corrosion than a Neodymium magnet, and usually does not require coating or plating. OEM Customized Dimension Orientation Magnetized Tile Gluing SmCo Magnets

    Generally, arc segments are anisotropically aligned through the outer and inner radii of the segment. After the magnet has been surface ground to profile the Arc radius or pressed, we magnetise it through the radius of the arc.
