Type: Permanent
Brand Name: rainbow magnet
Means of Transport: Ocean,Land,Air
Packing: standard carton by sea or b...
Application: Industrial Magnet
Composite: Rare Earth Magnet

Metal samarium, cobalt, copper, iron, zirconium, according percentage to melting, grinding, profiling, sintering, aging, and make of various grades.

Samarium cobalt magnets are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as rings, blocks and discs.
According the composition, we divide two of SMCO: Sm2CO17 and SmCo5
According the process, we divide to sintered Smco and bonded Smco
SmCo5
SmCo5's physical character and ductibility is better than Sm2Co17,
Compare Sm2Co17, the price is higher, it is not easy brittle,The (BH) max range is from 16 to 25, maximum working-temperature 250°C. The physical character and ductibility is better than Sm2Co17, so SmCo5 is easier to be machined thin thickness disc such as very small Samarium cobalt magnets cylinder with size: D2xh2mm or ring wall and complex shapes which Sm2Co17 are difficult to make.
