China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Samarium cobalt magnet is also a kind of rare earth magnet, the magnetic force is weaker than neodymium iron boron, it is undoubtedly a better choice in some special environments or applications, such as applications involving high or very low temperatures. If you need to customize samarium cobalt permanent magnet magnet, magnet manufacturer Courage think you need to read about it.
Technical data on the magnetic properties of samarium cobalt magnets;
Residual Magnetic Inductance (Br): the maximum magnetic induction that can be achieved at the surface of the magnet. smCo5 series (first generation samarium cobalt magnets), these materials typically provide residual magnetism of about 0.86 to 1.16 tesla (T). sm2Co17 series (second generation samarium cobalt magnets), these improved samarium cobalt magnets can achieve higher residual magnetism values of about 1.00 to 1.20 Tesla.
Coercivity (Hc): Reflects the magnet's ability to resist external magnetic interference. Samarium Cobalt magnets usually have high coercivity, generally between 12-30 kOe.
BHmax (Maximum Magnetic Energy Product): Measure the maximum energy provided by the magnet, unit is MGOe. The BHmax of Samarium Cobalt magnet is usually 16-32 MGOe, which shows the strong magnetic performance.
Working temperature: An important advantage of samarium cobalt magnet is its high temperature stability. The maximum operating temperature can be 300°C or more, depending on the alloy composition.
Samarium cobalt magnet common 3 kinds of shapes
Besides the above, samarium cobalt magnets can also be processed in other complicated shapes, such as trapezoid, oval and other special shapes, which can be processed according to your requirements.
How to choose samarium cobalt magnet grade?
SmCo5 series and Sm2Co17 series are more common, SmCo5 is suitable for some low and medium power applications where the magnetic field strength requirement is not too high, and it is more economical.Sm2Co17 is suitable for high performance and high power requirement applications, such as high-precision motors, aerospace and so on, if the applications need to work in high temperature environment (for example, aerospace, automobile engines, high-temperature motors, etc.), you can choose the Sm2Co17 series or higher grades. Sm2Co17 series or higher grade samarium cobalt magnets.
Safety Precautions for Samarium Cobalt Magnets
Samarium Cobalt magnets are hard and very fragile with high magnetic strength, they can also be drawn together with great force, if dropped or attracted together they will shatter or break. Therefore, they need to be handled and packed carefully to prevent injury or damage to the magnets.
Do samarium cobalt magnets need to be plated down?
Many people have this consideration, samarium cobalt magnets because of good corrosion resistance, the general environment can be used without plating, but if it is used in acidic or alkaline or harsher environments can be added plating protection.
Would it be better to go with NdFeB?
This mainly depends on your requirements for a magnet, if only strong magnetic requirements, you can consider neodymium-iron-boron, if you need to withstand high temperature (>250 ℃), and the magnetic requirements, samarium cobalt is really a good choice, the following is a few common permanent magnets magnetic properties of the data comparison picture.
