China SmCo Samarium Cobalt Magnets

$59865

Samarium cobalt magnet is mainly formed by the metal samarium, cobalt and some other rare earth elements of the permanent magnet.It has a high magnetic energy product, super low temperature coefficient,and the operating temperature can up to 300 ℃.At the same time, it has a strong corrosion resistance and oxidation resistance. Therefore, SmCo magnetic steel usually does not need to be electroplated, and is widely used in motors, meters, sensors, engines, radar and for other high-tech fields.
BASIC PROPERTIES OF SAMARIUM COBALT MAGNETS
– the main element is samarium, cobalt, and some other trace elements
– high temperature sintering (Shaped by mold firstly, than sintered by high temperature)
– SmCo Magnet material is bright gray, usually be plated by nickel
– The maximum operating temperature is up to 250-300 ℃, it is suitable for many kinds of high-performance motor
– mainly divided into two types of 1: 5 (SmCo5) and (Sm2Co17)
– samarium cobalt magnets are mostly in round shape.The thickness is 1/8 of the diameter, and be magnetized through thickness
