Samakoba magnet
Samarium-cobalt magnets are sintered products primarily composed of samarium and cobalt. They possess excellent magnetic properties, second only to neodymium magnets. They are also resistant to high temperatures, but they are brittle, so care must be taken when handling them. Please start by trying the stock items. If you order in larger quantities, there will be a lot discount, so please consider it.
It's broken!
There is a possibility that it may break due to impacts such as suction or dropping. In particular, neodymium magnets and samarium-cobalt magnets have strong magnetic forces, and if they are attracted with too much force, there is a high risk of damage, so care must be taken when handling them. Please be careful not to attract nearby magnetic materials immediately after removal. Additionally, magnets with countersunk holes that can be fixed with countersunk screws or bolts may break if tightened too much. Please consider the optimal tightening torque that will not damage the magnet.
Utilized in various fields such as MRI, pacemakers, electronic devices, audio equipment, communication devices, and automobiles! Immediate shipping available from just one magnet, with no need to hold inventory!
Permanent magnets are utilized in various fields by applying attraction and repulsion forces, as well as electromagnetic induction and electromagnetic forces, and further demand is expected to increase in the future.

Micro products and high precision are one of our strengths, and we can offer samples of magnets for free.
It is a molded sintered product primarily composed of samarium and cobalt, available in two material types: 1-5 series (SmCo5) and 2-17 series (Sm2Co17). It has a very strong magnetic force, second only to neodymium, and possesses heat resistance. However, due to its brittleness, care must be taken in handling to avoid chipping or cracking. Additionally, it is resistant to rust, so surface treatment is not necessary, but surface treatments such as plating can be applied to prevent chipping. Compared to neodymium magnets, the magnetic force is slightly reduced (about 1/4 lower), but it is still a very powerful magnet. The change in magnetic force with temperature is relatively small, making it suitable for applications requiring temperature stability and high-temperature use.
