| Raw Material Ratio | Energy Density | ReversibleTemp.coefficient |
SmCo5 | Sm:Co=1:5 | 25MGOe | - 0.05% / ℃ |
Sm2Co17 | Sm:Co=2:17 | 32 MGOe | - 0.03% / ℃. |
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 magnets can provide a maximum magnetic energy product of 25
MGOe 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. It also contains other elements,
such as iron, copper, zirconium and hafnium in a small amount. The
magnetic energy product of this property is higher, up to 32 MGOe,
and the reversible temperature coefficient is - 0.03% / ℃.
Mianyang Hengxin Magnetic Materials Co., Ltd. was founded in 1999,
specializing in the manufacture and development of sintered
samarium cobalt permanent magnet materials and devices; after years
of development, it has formed a production capacity of 500 tons of
samarium cobalt permanent magnet materials per year, and is the
main manufacturer of samarium cobalt permanent magnet materials and
devices in China.
