Dear Sir: How are you! We at Internet do imports and exports commerce operation. 1.Brief introduction of institute Zhongkangda Institute of Nano-meter Technology Apply Beijing is the comprehensive stock enterprise gathered scientific research, production and market. Its institute has a complete production technique of nano-powder, Siping nano-material device ltd. Corp., a specialist group of nano-material application research related widely to trade, and relative research project. Production process----application research----specialist group-----market development consists of the substantial base and prosperous future of the institute development. 2.Production technique and devices of pure metal nano-powder, where devices of SNB-2A, SNB-3 and SNH-3 styles are available. 3.Various pure metal nano-powder. (The pure physics device processes) For example, Fe, Co, Ni, Cu, Al, Mg, Au, Ag, Pt, W, Mo, Ti, Mn, Pd, Bi, Cr, V, Zn, Fe-Ni alloy, Fe-Co alloy 1Cr18Ni9Ti (Stainless steel), W-Ni-Fe alloy and W-Cu alloy etc. The average particle size is 30-70nm, and the purity is more than 99.9%, where the metal nano-powder of Al and Mg etc. is the high property materials necessary for missile and rocket combustion-aided agent; nano-powder of metal Ti is the high property anti-corrosion material, especially being used broadly in the field of high property anti-corrosion paint.
