What are the components of samarium and cobalt?
SmCo5 magnet is composed of SmCo alloy with SM CO ratio of 1-5, that is, one SM atom and five co atoms. According to weight, SM accounts for 36% of the total. This SmCo alloy usually contains 36% SM and a small amount of Co. this series of SmCo magnets can provide a maximum magnetic energy product of 25mgoe and a reversible temperature coefficient of - 0.05% / ℃. In addition, this series is easier to calibrate to a specific magnetic field than Sm2Co17 series. The Sm2Co17 magnet consists of SmCo alloy with a SmCo ratio of 2:17, i.e. 2 SM atoms and 17 co atoms. It also contains other elements, such as iron, copper, zirconium and hafnium, but the amount is very small. The magnetic energy product of this property is higher, up to 32 mgoe, and the reversible temperature coefficient is - 0.03% / ℃.
The specific proportion is SM: 23-28%; Rare earth metal cobalt: 48-52%; Metallic element Fe: 14-17%; Metal element Cu: 5-7%; A small amount of Zr: 2-3 was added.
