Properties of samarium cobalt permanent magnets
1. Samarium cobalt permanent magnets have excellent corrosion and oxidation resistance, so they do not require any coating:
2, samarium cobalt permanent magnet has high magnetic energy product and high coercivity, its magnetic energy product can be as high as 239kJ /m3(30MGOE), magnetic performance is better than aluminum-nickel-cobalt permanent magnet and ferrite permanent magnet, is ferrite permanent magnet 8 times, aluminum-nickel-cobalt permanent magnet 3 times. Therefore, the permanent magnet component made of SMCO permanent magnet system has light weight, small volume and stable performance, which can be used in electroacoustic telecommunications equipment.
3. Samarium cobalt permanent magnet with high Curie temperature and small temperature coefficient can be used at a high temperature of 300 degrees.
4. Samarium cobalt permanent magnet has high brittleness, high hardness, low bending strength, tensile strength and compressive strength, so it is not suitable to be used as structural parts.
5. The main component of samarium cobalt permanent magnet is cobalt metal (Co99.95%), so it is expensive.

The components of samarium and cobalt?
Samarium-Cobalt magnet also named SmCo magnet by most customers, SmCo Magnet is manufactured by process called sintering and bonding. Our Company only supplies the sintering magnet, grade SmCo5 and Sm2Co17. The Magnet streng is weaker than NdFeB magnets, but more stronger than Ferrite Magnets. SmCo is the most expensive than other magnets. Magnet properties is very stable, has good resistance to corrosion and oxidation resistance.
SmCo magnet, a type of rare earth mgnet, is a strong permanent magnet of an alloy of samarium, cobalt, Iron and the other trace elemets. This high properties of SmCo magnet is namely series 1:5 and 2:17. And the highest working temperature can reach 300℃, melting temperaure reaches 1300℃. It has high corrosion and antioxidant capacity, generally do not need coating protection.
Hand it carefully by packing, because SmCo magnets are brittle and prone to cracking and chipping.
SmCo Series 1:5
SmCo Series 1:5 has one atom of rare earth samarium and five atoms of cobalt. By weight this magnet alloy will typically contain 36% samarium with the balance cobalt. SmCo magnets generally have a reversible temperature coefficient of -0.05%. The maximum working temperature is about 350 ℃.
SmCo Series 2:17
SmCo Series 2:17 are age-hardened with a composition of two atoms of rare-earth samarium and 13-17 atoms of transition metals(TM). The TM content is rich in cobalt, but contains other elements such as iron and copper. Other elements like zirconium, hafnium, and such may be added in small quantities to achieve better heat treatment. By weight, the alloy will generally contain 25% of samarium. The maximum energy of these alloys ranges from 24 to 30 MGOe. SmCo magnets generally have a reversible temperature coefficient of -0.03% ℃. The maximum working temprature is 350℃
| Raw Material Ratio | Energy Density | ReversibleTemp.coefficient | |
| SmCo5 | Sm:Co=1:5 | 25MGOe | - 0.05% / ℃ |
| Sm2Co17 | Sm:Co=2:17 | 32 MGOe | - 0.03% / ℃. |
