The magnetic performance of N35 (which can be simply understood as suction) is slightly higher than that of N33SH, but its temperature resistance is not as high as that of N33SH, so it is generally only suitable for use in the environment below 80 degrees.
The upper limit of magnetic properties of N33SH is the lower limit of magnetic properties of N35, but the price of N33SH is much higher than that of N35.
The application of magnets should aim at the application fields and purposes, and achieve good cost performance through the combination of magnetic circuits.
If it helps, please adopt it.
