A, high temperature performance brand
The high temperature resistance of magnets is generally expressed by different brands such as N, M, H, SH, UH, EH, AH, etc. Among them, N is the general performance level, and the maximum temperature it can withstand is 80℃, M is the medium performance level, the maximum temperature it can withstand is 100℃, H is the high performance level, and the maximum temperature it can withstand is 120℃, while brands such as SH, UH, EH and AH can withstand higher temperatures.
Second, the relationship between magnetic force and high temperature resistance
Generally speaking, the magnetic force is inversely proportional to the high temperature resistance of magnets. In other words, as the temperature of the magnet increases, the magnetic force will gradually decrease. Therefore, when using magnets in high temperature environment, it is necessary to choose the appropriate magnetic force and brand according to the specific situation.
Third, the relationship between size and high temperature resistance
The size of the magnet will also affect its high temperature resistance. Usually, smaller magnets have better high temperature resistance than larger magnets. This is because the smaller magnet radiates heat faster, so it can withstand higher temperatures.
To sum up, choosing the appropriate brand, magnetic force and size of the magnet is an important factor to ensure the high temperature resistance of the magnet. In practical application, it needs to be selected according to the specific situation, so as to ensure that the magnet shows the best performance and durability in high temperature environment.
