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.

MPCO Magnets is specialized in manufacturing and supplying samarium cobalt magnets applied in various industrial applications. We have advanced technology, rich experience, and professional engineering technicians in this field. If you require a specific size, please contact us for a custom SmCo magnet quote.

Because of strong corrosion resistance, sintered SmCo magnets usually do not need any coating. If any coating is required, nickel, zinc, tin, epoxy, Teflon and other types are available.

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.

Servo Motor Sintering Samarium Cobalt Magnets

We carry a limited number of standard parts because precise specifications usually vary from one customer to another, requiring bespoke items to be manufactured. For prototyping, we can grind standard blocks into an arc segment using specially profiled grinding wheels. When full-scale production is required, the magnet is pressed to shape in a tool, prior to the sintering process as this is more efficient and cost-effective than grinding from blocks, but importantly from the same raw material grade for consistency from prototyping right through to production.

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.
Tolerances – For as-pressed material, tolerance on the thickness (direction of magnetization) is +/- .005”. Other dimensions are +/- 2.5% or +/- .010”, whichever is greater.

Machining – Since samarium cobalt magnet material is prone to chipping and cracking, it does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust.
