What are the components of SmCo?

SmCo₅ magnet is composed of SmCo alloy with Sm Co ratio of 1:5. 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 magnet can provide a maximum magnetic energy product of 25MGOe and a reversible temperature coefficient of - 0.05% / ℃. At the same time, this magnet 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. 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.
