Magnetic Cobalt Nanopowder, Absorbing Materials Cobalt Nano Powders

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.

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

Ultrafine Multi Functions Co Cobalt Nanoparticles can be used in various fields, such as magnetic fluid, hard alloy, high efficiency catalyst battery electrode material, High efficiency electromagnetic shielding coating, etc. Nano Co powders are available for nano, submicron and micron sizes.

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.

High purity aluminum nitride nanoparticles is widely used for ceramic substrate.

Silicon oxide nano powders (SiO2,20NM,99.8%,Amorphous) Silicon oxide nano powders as the amorphous white powder, is a kind of non-toxic, tasteless, no pollution non-metallic materials. silicon oxide nano powders modification: 1. Alcohol, acid modification Experiments showed that alcohol and acid compounds will react with a large number of -OH of silicon oxide nano powders surface, so organic groups are grafted in the surface of nanoparticles, and the hydrophobic properties of the modified powders got improved, so as to improve the compatibility of the nano powders and organic matter 2. Surfactant modification 1) by physical adsorption surfactant is adsorbed on the surface of nanoparticles; 2) certain groups of surfactant react with -OH of the surface of the particles,which achieve the goal of the surface modification of the particles. 3. The silane coupling agent modification Experiments show that the coupling agent reduce the interaction between particles, and influence degree of different coupling agent on the modified samples is different. Stock# M600 and M602: hydrophilic SIO2, 10-20NM and 20-30NM,99.8% Stock# M603 and M606: hydrophobic SIO2,10-20NM and 20-30NM,99.8%                        1kg per bag for sample, 10kg per bag for the hydrophilic, 5kg per bag for the hydrophobic The main application of silicon oxide nano powders       HONGWU NANO silicon oxide nano powders, more than 8 years of market and technology development, has been widely used in electronic packaging materials, polymer composite materials, plastics, coating, rubber modified, paint, ceramics, adhesive, glass fiber reinforced plastic, drug carrier, cosmetics and sterilization field, which bring epoch-making significance for an upgraded version of a traditional product.

Copper is the basis of functional powder material of high-tech and high value-added, but also one of the fastest developing areas of materials hot products.
