Samarium Cobalt Disc Magnets
Samarium Cobalt (SmCo) Disc Magnets
Samarium cobalt (SmCo) disc magnets are strong permanent magnets that perform well in high or very low temperature environments. Part of the rare earth magnet family, SmCo disc magnets have a high resistance to corrosion or demagnetization. Because of their superior magnetic properties, SmCo disc magnets are ideal for applications where high-temperature performance is critical, space is a limiting factor and high-magnetic strength is required.

* $15.00 total minimum order (excluding shipping & tax if applicable) - Items can be combined to reach the minimum amount.
*Note: The approximate pull info listed is for reference only. These values are calculated assuming the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure.

Standard Dimensional Tolerances for SmCo Disc Magnets
Standard diameter tolerances for Rare Earth Magnets (SmCo & NdFeB) based on the following dimensions:
- +/- 0.004” on dimensions ranging from 0.040” to 1.000”.
- +/- 0.008” on dimensions ranging from 1.001” to 2.000”.
- +/- 0.012” on dimensions ranging from 2.001” to 3.000”.
*Tolerance on thickness is +/-0.004” regardless of size.
Safety Precautions for Samarium Cobalt Disc Magnets
SmCo magnets are hard, very brittle and high in magnetic strength. They can also snap together with great force, and chip or break if dropped. Therefore, they require careful handling and packing in order to prevent injuries or damages to the magnets.
