Samarium cobalt permanent magnet (also known as SmCo magnet) is a kind of permanent magnet. A big advantage of samarium cobalt magnets is that they can operate at temperatures up to 300 degrees Celsius. Widely used in applications requiring high operating temperatures as well as high resistance to corrosion and oxidation.

Samarium cobalt magnets are the second generation of rare earth permanent magnets, mainly divided into 1:5 type (SmCo5) and 2:17 type (Sm2Co17). Next, the manufacturer of samarium cobalt magnets will take you to understand the difference between samarium cobalt SmCo5 and samarium cobalt Sm2Co17.

1. Different ingredients

SmCo1:5 magnets are also called SmCo5, the main components are samarium, cobalt, praseodymium, or just pure samarium cobalt, SmCo2:17 magnets are also called Sm2Co17, the main components are samarium, cobalt, copper, iron and zirconium;

2. Different physical properties

SmCo5 has a maximum operating temperature of 250°C, while Sm2Co17 has a maximum operating temperature of 350°C. Compared with Sm2Co17, SmCo5 is brittle and much easier to process.

3. The grades of grades are expressed differently

SmCo5 is represented by YX; Sm2Co17 is represented by YXG;

4. Comparison of physical properties

The magnetic energy product of SMCO5 magnetic steel is lower than that of Sm2Co17, but its machinability is better, and it is suitable for machining parts with special shapes. The magnetic energy product of Sm2Co17 can reach 28MGOE, the magnetic performance is excellent, the price is cheaper than SmCo5, and the current consumption is relatively large.

The above content is a comparative introduction of the two types of samarium cobalt magnets, and I hope it will be helpful to you.
