SmCo magnets are also called SmCo magnets, SmCo permanent magnets, SmCo permanent magnets, rare earth cobalt permanent magnets, etc. In fact, it is also one of the types of magnets, and it also has specialized manufacturers. The following briefly introduces SmCo magnets for you, hoping to bring you some help. Introduction SmCo magnet is a kind of magnetic material made of rhenium, cobalt and other rare earth metal materials, melted into alloy, pulverized, pressed, and sintered. The maximum working temperature can reach 350 ° C, and the negative temperature is not limited. When the working temperature is above 180 ° C, its temperature stability and chemical stability exceed NdFeB permanent magnet materials. Has strong resistance to corrosion and oxidation; it is widely used in aerospace, defense industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes Wait. SmCo magnets are more resistant to corrosion and rust than high-temperature NdFeB magnetic steels. SmCo magnets will be modified by alloying, which will completely change the world's rail transit mode. SmCo magnet is a kind of rare earth magnet. It is a kind of magnet made of samarium, cobalt and other metal rare earth materials. Successfully developed in 1970, samarium cobalt magnets are the second most magnetic magnets today, with a high maximum magnetic energy product (BHmax), high coercivity, fragility, and fragility. The maximum magnetic energy product of samarium cobalt magnets ranges from 9 MGOe to 31 MGOe. SmCo magnets have two kinds of composition ratios: (Smium atom: Cobalt atom) 1: 5 and 2:17. For example, the maximum magnetic energy product of 2:17 alloy is 26 MGOe, the coercivity is 9750 oersted, the Curie temperature is 825 ° C, and the maximum operating temperature is 350 ° C
1. Very good coercivity.
2. Good temperature stability.
3. Expensive and susceptible to price fluctuations (cobalt market price sensitive).
Main hazards 1. SmCo magnets are easily broken. When handling them, you must wear goggles. 2. Hitting the magnets together may cause the magnets to shatter, which may cause potential danger. 3. SmCo manufacturing is made by a process called sintering, and sintering all materials, it is very likely that cracks will occur inside. The magnet does not have mechanical integrity, but only has the function of preparing a magnetic field. Therefore, special mechanical systems must be designed to give the overall system sufficient mechanical reliability.
