How high temperature can it withstand?
Recently, many customers have asked about high temperature magnets, so which magnets have high temperature resistance? What high working temperature can it withstand? Next, let Xiaochen introduce to everyone what are the high temperature resistant magnets.
1. AlNiCo Magnet
1. It can be operated at a temperature of 600 degrees Celsius;
2. It is an alloy composed of aluminum, nickel, cobalt, iron and other trace metals, with good machinability.
Two, neodymium iron boron magnet
1. Its working temperature can reach 200 degrees Celsius;
2. Its magnetic performance is very high, among which (BH)max is more than 10 times that of ferrite. The neodymium iron boron magnets used in brushless motors usually choose 120 degrees-150 degrees;
3. After the high temperature resistant neodymium iron boron magnet magnetic grade, there will be the following signs:
M (80-100℃), H (100-120℃), SH (120-150℃), UH (150-180℃), EH (180-200℃).
4. The magnetic field strength of the neodymium iron boron magnet will be affected by the surrounding working temperature. In the working temperature range, as long as the temperature rises, the corresponding magnetic force will be weakened. This can refer to our previous article "What will weaken the magnetic force of a strong neodymium iron boron magnet?".
3. Samarium Cobalt Magnet
1. Its working temperature can reach 250-350 degrees Celsius;
2. The price of this magnet material is very expensive, so its development is limited, not as high as the commercial value of neodymium iron boron magnet;
3. As a rare earth permanent magnet, samarium cobalt not only has a high (BH) max (14-28MGOe), but also has good coercivity and temperature characteristics. Samarium cobalt magnets are more suitable for working at high temperatures than neodymium iron boron.
Four, ferrite magnet
1. Its working temperature can reach 250 degrees Celsius;
2. Because of its excellent temperature resistance, low cost and moderate performance, it has become a widely used permanent magnet.
Packing Neodymium Magnet is your good choice.
