China Neodymium And Ferrite Magnets Manufacturer & Supplier 
You may not know, samarium cobalt magnets is also a rare earth magnet, it is compared with rare earth neodymium magnet, the biggest advantage is high temperature resistance, corrosion resistance, its limit temperature resistance is 350 ℃ or can be higher? Look down, you will get something.
Let's start with the conclusion that samarium cobalt permanent magnets have an ultimate temperature resistance of up to 500 degrees Celsius.
Are all samarium cobalt grades able to withstand 500℃?
Not, but exclusive customized, generally temperature resistance 300-350 ℃, to achieve temperature resistance 500 ℃ at present in our country there are some magnet manufacturers have been able to achieve.
The picture is high temperature resistant samarium cobalt round magnets
Practical application of Samarium Cobalt magnets with 500℃ extreme temperature resistance
Aerospace: In aviation engines and spacecraft, magnets need to work stably at high temperatures. Samarium cobalt magnets are widely used in components such as control systems, sensors and motors in aerospace by virtue of their excellent high temperature performance.
Military equipment: Some military equipment needs to work under extreme environment, such as missile and radar systems, the high temperature stability of Samarium Cobalt magnets makes it a reliable choice.
High temperature motors: some industrial motors generate high temperature when running for a long time, Samarium Cobalt magnets can ensure that these motors can still run efficiently at high temperature without affecting the overall performance due to the deterioration of magnetic properties.
Sensors and testing equipments: some precision sensors need to test the magnetic field in high temperature environment, SmCo magnet's stable magnetic field characteristic makes it a good choice for these equipments.
Nearly 500 ℃ limit temperature, samarium cobalt magnets can still maintain a fairly high remanent magnetism (Br) and coercivity (Hc), I have tested, will be a diameter of 10mm, thickness of 5mm round samarium cobalt magnets into 450 degrees Celsius of the tin furnace, bake before baking and after no obvious changes, can be pull 1KG weights.
Above is the introduction of the extreme temperature resistance of samarium cobalt magnets, for most commercial applications, the standard working temperature range of samarium cobalt magnets is from low temperature (even negative temperature) to 350℃, if you need higher, please consult your supplier if it is possible.
