Why Choose a Samarium Cobalt Magnet?

Samarium Cobalt magnets offer excellent thermal stability and strong resistance to oxidation. They are often selected for specialised applications where standard neodymium magnets may experience reduced performance or require additional corrosion protection.

The raw, uncoated surface is a normal characteristic of SmCo material. These magnets are hard and brittle and should be handled carefully to avoid chipping or impact damage.

Important: The stated pull force is theoretical and assumes ideal contact with clean, flat and sufficiently thick steel. Actual performance varies with the application, air gap, surface condition and direction of load.
