Resistant samarium-cobalt magnets SmCo
Similarly to recently very popular neodymium magnets (NdFeB magnets), also samarium magnets (SmCo) belong to the strongest magnets. Their power is almost comparable with the power of neodymium magnets.

Main benefits of samarium magnets
However, on contrary to neodymium magnets, they are characterized with one very remarkable positive feature, i.e. their temperature resistance. The temperature resistance may be even up to 300 °C (in neodymium magnets this is 200 °C at maximum).
Another great strength of these magnets consists in their resistance against corrosion without a need of a surface treatment - therefore the SmCo magnets are supplied without any surface treatment.
Composition of the SmCo magnet
According to the ratio of main elements contained in these magnets, samarium - Sm and cobalt, Co, we divide them into two main types: SmCo5 and Sm2Co17.
We guarantee operative delivery dates

Ferrite magnets are classical, black magnets. Based on their production technique they are divided into the isotropic mag- nets and anisotropic magnets.
Office magnets
They are finding their applica- tion not only in offices, but also at schools n' homes. we're selling color magnets as well as frequently used ferrite magnets.
Coated magnets
Magnets are coated with a thin PVC layer; this way they become free of sharp edges so they do not vilify and do not damage fixed objects.
Clip magnets
These magnets are very strong neodymium NdFeB magnets coated by a rubber layer protecting them against damaging.
Water resistant rubber-coated neodymium magnets
These neodymium magnets are completely covered with a rubber layer providing the following benefits: water resistance and protection against scratching.
