This disc SmCo magnet is made of Samarium Cobalt rare earth magnetic materials under ISO 9001 quality systems. The material is Sm2Co17 and the grade is 26. This magnet is axially magnetized so the N and S poles are on the flat surfaces.
SmCo magnets are comparable in the magnetic strength to neodymium magnets but have a higher working temperature. They are majorly used in the industries when the high temperature is present. There is no coating for this magnet.
The followings are the magnetic characteristics of this SmCo magnet,
Br: 10.4 kGs
Hcb: 9.8 kOe
Hcj: 10.6 kOe
(BH)max: 26 MGOe
Maximum Normal Operating Temperature: 300 Celsius or 572 Fahrenheit
Holding Force: Approximately 6.9 lbs.
Pole Orientations: Axially magnetized, i.e. the N and S poles are on the flat surfaces.
Applications: Holding, motors, generators etc. For crafting magnets, please choose neodymium magnets instead.
SmCo magnet is mechanically weak, but magnetically very strong. They should be packed properly in order to help user to handle them safely. High Performance Disc SmCo Magnets for Instruments, Dia 1/2″X1/4″ Axially Magnetized Samarium Cobalt Magnets Disc 572F Temperature

Circulator is a radio-frequency passive device in the mobile communication field that allows microwave or radio-frequency signal transmits in unidirectional ring. The one-way transmission characteristics are based on the gyromagnetic property of gyromagnetic ferrite. Gyromagnetic ferrite is a kind of ferrite material which polarization plane constantly rotates around transmission direction when the plane polarized electromagnetic wave travel through the ferrite in one particular direction under high frequency magnetic field. The one-way transmission characteristics are mainly served for mutual isolation between level and level or between level and system of radio-frequency equipment to ensure working independently, therefore, protect signal source and reduce frequency pulling, interference or unnecessary radiation which will efficiently improve circuit quality.
