custom industrial magnets should be called magnets. Magnets are now mainly divided into two categories, one is soft magnetic and the other is hard magnetic; soft magnetic includes silicon steel sheet and soft magnetic core; hard magnetic includes alnico, samarium cobalt, and ferrite Among them, the most expensive is samarium cobalt magnets, the cheapest is ferrite magnets, the highest performance is NdFeB magnets, but the performance is the most stable and the temperature coefficient is the best aluminum For nickel-cobalt magnets, users can choose different hard magnetic products according to different needs.After thousands of years of development, magnets have become powerful materials in our lives. By synthesizing alloys of different materials, the same effect as the magnetite can be achieved, and the magnetic force can also be improved. Artificial magnets appeared in the 18th century, but the process of making stronger magnetic materials was very slow, until AlNiCo was produced in the 1920s. Subsequently, ferrites were produced in the 1950s, and rare earth magnets were produced in the 1970s, including neodymium iron boron and samarium cobalt. So far, magnetic technology has developed rapidly, and strong magnetic materials have made the components more compact.Most magnetic materials can be magnetized to saturation in the same direction, which is called the magnetization direction. Magnets without orientation direction are much weaker than orientation magnets.Be very careful with the handling and storage of magnets. The magnets will stick together by themselves, which may pinch your fingers. When the magnets are attracted to each other, the magnet itself may also be damaged due to collision. For larger magnets, plastic or hard paper spacers should be added between each piece to ensure that the magnets can be easily separated.At present, the highest performance magnets are rare earth magnets, and among the rare earth magnets, Ring Neodymium Magnet boron is the most powerful magnet. But in an environment above 200 degrees Celsius, samarium cobalt is the most powerful magnet.
