When it comes to magnets, it is estimated that most of them know the usefulness of magnets. However, when it comes to the nature of specific magnets, most of them are not clear. In fact, the so-called magnets can generate magnetic fields or materials, which are roughly divided into two. Kinds: permanent magnets and non-permanent magnets, while permanent magnets are simply powerful magnets, and the strongest magnets are neodymium magnets.
After thousands of years of development, today's magnets and development have become essential functional materials in our lives. At the same time, it also synthesizes alloys of different materials through advanced powder metallurgy process, which can simultaneously achieve the effect of exceeding the magnet and also maximize the magnetic force. In the 18th century, man-made magnets appeared, but the process of making higher magnetic materials became very slow, until the 1920s produced aluminum-nickel-cobalt (AlNiCo). Later, in 1948, ferrite was produced. In the 1970s, rare earth magnets [Rare Earth magnet] samarium cobalt (SmCo) were produced. In 1986, NdFeB was born, and it has become the world so far. The strongest magnet. As a result, physical magnetics technology began to develop rapidly, and magnetic materials also made the components more compact. Until 1999, Zibo Shengjin Magnet broke through the precedent of an industry with its own combination of 13,000 GS rare earth magnets. Since the promotion of the industry, China's rare earth magnet industry has ushered in a new world of rapid development.
