Application of Bismuth Bi powder:
Bismuth powder can be used as lubricant additive: when added 0.1 to 0.3% of Bi nanoparticles to grease in the friction process, the friction surface will form a self-lubricating, self-laminating mask to protect the machine, which will significantly improve the grease performance.
Bismuth powder can be used in the metallurgical industry: can be used as the additives during the production of cast iron, steel and aluminum alloy, which can improve the cutting performance of the alloy.
Bismuth powder can be used as magnetic materials: bismuth has smaller thermal neutron absorption cross section, lower melting point, and higher boiling point, which enable it to be the heat transfer medium used in nuclear reactor. 

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

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