Introducing the development of magnets


For the magnet industry represented by high-strength magnets, it is almost everywhere in our lives. For this reason, the development of high-strength magnet manufacturers is also growing. As a leader in the industry, we are obliged to popularize some knowledge about high-strength magnets. Today, we will first take everyone to understand the development of the magnet:

High-strength magnet manufacturers introduce you to the development of magnets


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 very 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 high-strength magnets, and the strongest magnets are neodymium magnets.


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. It was made in the 1970s, and SmCo was born. In 1986, NdFeB was born, and it has become the strongest magnet in the world. As a result, physical magnetics technology began to develop rapidly, and the strong 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, and at the same time quickly Since the promotion of the industry, China's rare earth high-strength magnet industry has ushered in a new world of rapid development.


The above is the development process of magnets for high-strength 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.
