Medallions magnet

Samarium cobalt magnets have many customers called samarium magnet, sintered and bonded points, the only Division I supply sintered samarium cobalt magnets, grades are SmCo5 and Sm2Co17. NdFeB magnets Magnetic relatively weak, compared with ferrite, alnico magnet is strong, is the four most expensive magnets. Magnetic energy is very stable, with strong resistance to corrosion and oxidation resistance. SmCo magnet is mainly a mixture of metal samarium, cobalt, iron, and other trace elements having a high performance SmCo configuration 1: 5 and 2:17 SmCo permanent magnet. The maximum operating temperature up to 300 ° C, the melting temperature of 1300 degrees Celsius. Has a strong anti-corrosion and oxidation resistance, generally do not need protection coating. Since samarium cobalt magnets are very fragile, so be careful when handling the packaging needs. SmCo 1: 5 SmCo 1: 5 magnet generally contain more than 30% of samarium cobalt and a lot of energy product range from 18MGOe to 22MGOe, generally reversible temperature coefficient of -0.05% / ° C, the maximum operating temperature of 250 ° C. SmCo 2:17 2:17 SmCo magnet in addition to containing a large amount of samarium and cobalt, but also contain 13-17 species of transition metals, transition metal elements rich in cobalt, but also contain other elements such as iron, copper, zirconium, hafnium, etc. in order to achieve better thermal effects. BH range from 24MGOe to 30MGOe. Typically, reversible temperature coefficient of -0.03% / ° C, the maximum operating temperature of 300 ° C. Compared with other rare earth magnets, samarium cobalt magnets NdFeB magnetic relatively weaker than Alnico strong magnets, magnetic stability and maximum operating temperature higher than the NdFeB and ferrite magnets, alnico magnet relatively low. Price, samarium cobalt magnets are rare earth magnets inside the most expensive. Samarium cobalt magnets are mainly used in various sensors (auto parts), micro-motors, sputtering equipment Magnetic equipment, aerospace and other fields. Samarium cobalt magnets, there is radiation function can be applied to other areas of spacecraft. The final choice 2014-5-7 15:59:19 Introduction of Application: SmCo magnet is rare earth metal samarium and cobalt as a main component strategy, and iron, copper, zirconium, praseodymium and other metal smelting alloy material ratio, After crushing, pressing a magnetic material after forming, sintering and aging made with high magnetic properties (high energy product, high coercivity, high remanence); a very low temperature coefficient (-0.030% / ℃ ), high temperature (maximum temperature of 350 ℃), negative temperature is not limited to, operating temperature is above 180 ℃, the maximum energy product, temperature and chemical stability are more than NdFeB material; have it Strong resistance to corrosion and oxidation resistance. So SmCo magnet is widely used in aerospace, defense industry, microwave devices, telecommunications, medical equipment, instrumentation, wind power, all kinds of magnetic drives, sensors, magnetic processor, high-end motor industry. Magnetic pump applications: magnetic pump is an absence of fog dynamic seal leak fluid transfer machinery. Mainly for centrifugal vane pump design, the outer seal chamber has a rotating magnetic field, and by the action of a magnetic field to drive the magnetic seal chamber inside the rotor synchronously rotating member, the cavity is sealed inside the rotor member impeller driven to achieve the fluid acting. Due to the rotation axis of the stator components do not wear a shield seal. Thus ensuring zero leakage magnetic pump, no pollution. Samarium cobalt magnet with its stable energy product, high temperature (350 ℃) excellent performance, widely used in magnetic pump. Sensor Application: The sensor magnetic circuit system needs to provide a stable permanent magnetic material integrated magnetic, NdFeB maximum use temperature of 150 to 200 ° C, reversible temperature coefficient of -0.1 to -0.13% / ° C, can not meet requires high-end sensor magnet system, and the maximum temperature of 350 ℃, reversible temperature coefficient of -0.030% / ° C and NdFeB material has unparalleled corrosion resistance Sm2Co17 material into high-end sensor system is the most suitable Wing magnetic material.
