The position of samarium cobalt magnet in the magnet
Samarium cobalt magnet is an important rare earth magnet material, which is a mixture of samarium, cobalt and other rare earth elements. It has a high magnetic constant and good magnetic stability, and is one of the most widely used permanent magnets in the world. In the field of magnets, samarium cobalt magnets play an important role, which will be discussed in the following aspects.
1. Basic properties of samarium cobalt magnets
The basic performance of samarium cobalt magnets is very good, its remanence rate, coercive force and maximum magnetic energy product are all at a high level, which makes samarium cobalt magnets widely used in the fields of motors, permanent magnet linear motors, computers, communications and medicine. It plays an important role in it, especially in miniaturization and light weight.
2. Production of Samarium Cobalt Magnets
The production of SmCo magnets is mainly divided into two types: traditional metallurgical process and rapid solidification process. The traditional metallurgical process mainly adopts two methods of vacuum melting and powder metallurgy. The raw materials of powder metallurgy can be obtained by gas phase reduction method, sol-gel method and oxide plus reduction method. The rapid solidification process uses rapid cooling to prepare samarium cobalt magnets. The principle is to quickly reduce the temperature of molten metal to normal temperature to solidify, so as to realize the specific microstructure of samarium cobalt magnet materials, so as to achieve excellent magnetic properties.
3. Application of Samarium Cobalt Magnets
With the process of industrialization, samarium cobalt magnets are widely used in various industries. Including motorcycles, cars, wind power, mobile phones, TVs, stereos, headphones, power tools and household appliances, etc. Taking earphones and other consumer electronics products as examples, samarium cobalt magnets have become one of the best components for consumer electronics products such as earphones due to their excellent magnetic properties and small size. In the field of new energy, samarium cobalt magnets are applied to wind power generators, which can make wind power generators concentrate huge energy. In the automobile industry, SmCo magnets are widely used in automobile engines, transmissions, water pumps and electric vehicle drive motors, etc.
4. The development trend of samarium cobalt magnet
The application of samarium cobalt magnets has approached the limit in some fields, and there are still many problems in its production and application process. For example, the production of rare earth elements such as samarium is limited, the cost is high, and the safety and environmental protection pressure of mining areas are high. In this context, magnet-related industries have begun to explore new solutions, such as gradually developing the recyclability and reusability of magnetic materials, adopting low-cost materials and production processes, and developing environmentally friendly rare earth magnets. In addition, other magnet materials are used to replace samarium cobalt magnets, such as neodymium iron boron magnets, ferrite magnets
"Since 2006, we found Mr.Guo and get products from him. We used magnets under the earth for the gas and water pipe industries. We have met no problem. We have been working in very happy ways. We have many cooperation. Every year, we spent time together and sometimes, we invited him to Korea. He is our younger brother. Strongly recommended!!"

"I had email to Mr. Guo for rare earth magnet requirements. They replied my e-mail promptly, and were very professional. Mr. Guo’s team still continues to deliver rare earth magnets to our agreed specifications with a very high quality standard since 2012. His team is very professional and thorough with its work. Based on my experience, I would highly recommend them."
