Rare earth SmCo countersunk ring magnets have very high coercivity, which means they are not easy to demagnetize. SmCo countersunk ring magnets are known by their ability to work at temperatures up to 350 degrees Celsius. Generally speaking, it is rare earth countersunk magnet, which can provide a strong magnetic force. Because of the hardness of SmCo materials, it is necessary to use professional tools to machine countersunk ring SmCo magnets.If you need screwed on or mountable samarium-cobalt(SmCo) magnets,please contact us now for quotation. Beside countersunk SmCo magnets, this SmCo is also available as disc magnets,block magnets,cylinder magnets and arc magnets.

Care required for handling Samarium Cobalt Countersunk Magnets:

SmCo countersunk magnets are very strong and brittle, appropriate handling and packing required to ensure safety and prevent damage.

The brittle nature of the alloy can lead to flying chips if the magnets are allowed to impact each other or a solid surface. Most receiving departments are not familiar with the strength of Samarium Cobalt magnets and this can result in injury or broken parts. All personnel that may come in contact with this alloy should be made aware of the dangers of handling these magnets. Large SmCo countersunk magnets can become a pinching hazard if caution is not exercised. We remind all customers to handle countersunk SmCo magnets with care.
