Cobalt Co Powder Application:
Electromagnetic-wave absorption; Electromagnetic-wave radiation shielding for cellar phones; Ferrofluids; High density magnetic storage; Magnetic inks; Magnetic toner in xerograph; Contrast agents in magnetic resonance imaging……


Cobalt Co Powder Cautions: 
1. Cobalt powder has flammable hazards, so it should be gently placed and to avoid violent vibration and friction. 

2. Metal nano cobalt powder should be prevented from moisture, heat, impact and sunlight.

3 .The user must be a professional (This person must know how to use this product.)

Storage Condition of Cobalt Co Powder:
Damp reunion will affect Co powder dispersion performance and using effects, therefore, Cobalt Co Powder should be sealed in vacuum packing and stored in cool and dry room, the Cobalt Co Powder can not be exposure to air. In addition, the Co powder should be avoided under stress.

Packing & Shipping of Cobalt Co Powder:
We have many different kinds of packing which depends on the Cobalt Co powder quantity.
Cobalt Co powder packing:vacuum packing, 100g, 500g or 1kg/bag, 25kg/barrel, or as your request.
Cobalt Co powder shipping:could be shipped out by sea , by air, by express?as soon as possible once payment receipt.
