Ultrafine Multi Functions Co Cobalt Nanoparticles

We are high-activity megnetic cobalt nanoparticles manufacturer.

Cobalt Nanopartilces is a high density magnetic recording materials and with multi-function .  

Nano Cobalt Powder have high density magnetic recording,high coercive force,high signal-to-noise ratio and oxidation resistance

Nano cobalt powder is magnetic, spherical, widely used in cemented carbides coating materials.

Cobalt nanopowder, 100-150nm, 99.9%,widely used as magnetic materials, or absorbing materials.

Nano cobalt wet powder, 20-30nm,100-150nm, 99.9%, more easy to dispersed and safe to transport out.

      Hongwu International Group LTD offer a highly diverse range of Cobalt particles grades with average grain sizes from approx. 20nm to 1um. We provide technical support in the selection of the powders suitable for specific applications. Stock# A050, 20NM Cobalt nano particles Stock# A051, 100-150NM Cobalt nano particles Stock# B052, 1-3UM Cobalt particles, grey solid powder.       Cobalt particle is the best binder for cemented carbide. Although iron, cobalt powder, nickel powder generations have made some progress, still more than 90% of the carbide cobalt used as binder. In order to improve the organizational structure of carbide, improve performance and reduce the size of cobalt powder has very important significance. To reduce the average particle size of the binder powder can improve the transverse rupture strength, hardness and density. To use the ultra-fine cobalt powder manufacturing high-performance WC-Co cemented carbide, requests the cobalt nano particles average particle size to achieve to less than 500nm. In such particle size could produce excellent adhesive. With the small particle size Cobalt powder to make WC-Co whose abrasion resistance and crack resistance is much better than the alloy produced with coarse cobalt powder.        If you're interested in cobalt nano particles, please feel free to contac us. by Lyla

China factory direct offer ultrafine Cobalt ( Co) nanoparticles wet powder form. It has important uses in the electronic industry, magnetic materials, cemented carbide, surface spraying, chemical catalysis and other industrial fields, showing excellent performance.

Hongwu Nano supplies different carbon nanotubes, including single-walled, double-walled, multi-walled CNTs. Dispersion can be customized also. CNTs have excellent properties of catalyst, thermal, electric conduction, adsorption, mechanical, etc..

Besides pure monoclinic phase vanadium dioxide nanopowder, tungsten doped vanadium dioxide(W-VO2) nanoparticle can be customized also, to lower the phase-transition temperature.

White carbon black, is sio2 nanopowder, particle size 20-30nm, 99.8% purity, has hydrophic and hydrophobic two kinds.

Vanadium dioxide (VO2) is the most widely studied and applicated inorganic thermochromic material. Pure Phrase(M-VO2) vanadium dioxide phase transition temperature is 68℃. By doping tungsten, the phase transition temperature can be reduced to room temperature near 20℃. Buy the material now, please contact us.
