SmCo magnets will outperform NdFeB magnets at temperatures above +150 to +180 degrees C.
SmCo magnets can be used at cryogenic temperatures (i.e. towards absolute zero, -273 degrees C).
The magnet shape, its environment, and the actual application affect how the NdFeB magnet will perform. Temperature is important as well as damp or wet conditions.

High Temperature Sintered SmCo Curved Magnets

When determining suitability, you should analyse the Intrinsic curve not the Normal curve.
By keeping the intrinsic working point above the ‘knee’ and ideally at the BHmax working point maximum performance is possible. Sintered SmCo Rare Earth Segment Motor Magnets YX-18

YX-22 Samarium Cobalt Curved Segment Magnet

Samarium Cobalt is also known as SmCo, Rare Earth Cobalt, RE Cobalt, RECo and CoSm.
Samarium Cobalt (SmCo) magnets are not as strong as the Neodymium (NdFeB) magnets (maximum energy product of between 30 and 50 MGOe) but they have three significant advantages. The SmCo magnets work over a wider temperature range, have superior temperature coefficients and have much greater corrosion resistance.

Samarium Cobalt (SmCo) magnets can be used over a massive temperature range. A few Neodymium magnet grades can be used at temperatures up to 220 degrees C. The SmCo magnets start to outperform the NdFeB magnets around 150-180 degrees C. Also, Samarium Cobalt magnets are ideal for very low temperature applications (SmCo can be used down to a few Kelvin above Absolute Zero) making them a first choice magnet for cryogenic applications. They can also be used in very high temperatures – up to +250 deg C or +300/+350 degrees C depending on the grade; the SmCo26 is rated to +300 degreec C)

Samarium Cobalt (SmCo) magnets contain less free iron than Neodymium magnets and therefore provide better corrosion resistance than Neodymium magnets. It is very rare for SmCo magnets to require protective plating (a notable exception is the use of nickel plating for soldering the magnets to printed circuit boards). Sm1Co5 contains no iron so has excellent corrosion resistance. Sm2Co17 has some free iron that may corrode on the magnet surface when exposed directly to water. Sm2Co17 is still, for most applications (other than marineenvironments) regarded as having good to very good corrosion resistance (in marine applications the magnet can be given a simple low cost protective coating such as NiCuNi to prevent any corrosion possibilities) and the corrosion resistance is still far superior compared to NdFeB.
