Magnets can be divided into NdFeB magnets, ferrites, samarium cobalt magnets, and AlNiCo magnets according to their materials. They can be divided into permanent magnets and ordinary magnets according to their magnetism. They can be divided into strong magnets and ordinary magnets according to their magnetism. What is the difference between.
1. High temperature resistance of powerful magnets: The extreme temperature and Curie temperature of powerful magnets are stronger than ordinary magnets. No matter which material is used, the strong magnetism is superior to that of ordinary magnets, so the limit temperature that the magnet itself can withstand is greatly increased, and the machine can be guaranteed to run at the temperature used by the machine.
Strong magnets are harder: Strong magnets add the density of rare elements, making them much harder than ordinary magnets. The collisions that cannot be avoided during use will not affect the integrity of the magnet. The general magnetite is fragile and cannot maintain its appearance for a long time.
2. Strong magnets have strong magnetic force: The common magnet is usually based on how many coins it attracts, while the strong magnet is several times, dozens or even hundreds of times its magnetic force. Strong magnets have strong magnetic force. Generally, workers who install them should be very careful to avoid personal injury, which shows how strong their magnetic force is.
3. Practicality and preservation of strong magnets: The strength of the magnets of strong magnets is not only stronger than ordinary magnets in performance, but also more practical than ordinary magnets, and can meet the special needs of various customers. And the preservation is incomparable, ordinary magnets cannot be used for a long time at all, while the preservation of strong magnets is complete and can be suitable for large-scale inventory in various situations.
4. The price of strong magnets: The price of strong magnets is definitely higher than that of ordinary magnets. Its inferiority also makes the price of ordinary magnets lower than that of strong magnets.
Strong magnets have good resistance: ordinary magnets will continuously demagnetize and demagnetize in the air. Strong magnets are mainly made of rare elements, and they have high coercivity. Under natural environment and normal conditions, they cannot affect their magnetic force at all, ensuring the stability of magnetic force. Different from the exposed magnet, the electroplating on the surface of the strong magnet can well ensure that the magnet is not corroded by substances such as acid and alkali.
