SmCo owns following advantages
. Possess strong magnetic properties - 5-7 times more powerful than ferrite
. Very steady in the conditions capable to cause corrosion
. Possess stable magnetic properties at high temperatures (to 350 degree )
. Excellent corrosion resistance capability, no coating is needed for surface protection
Packing:
Inner packing: small white box
Outer packing: Carton with OPP bag
Attribute characteristics
1. Very good coercivity.
2. Good temperature stability.
3. The price is expensive, vulnerable to price fluctuations (cobalt market price sensitive).
