Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

Cu-Zn alloy nanopowders, particle size 70nm, Cu:Zn=65:35, factory price. If need other particle size,kindly contact us for customize service to check feasibility, thanks.

Copper powder, have 0.2um, 0.3um, 0.5um,0.8um several size, is widely used in electronic paste.

Hexagonal Boron Nitride Nanopowders has nano size, sub-micron size, micron size,widely used in ceramic materials.

Hongwu International Group Ltd supply hexagonal boron nitride powder mainly in 100-200nm, 800nm, 1-2um, 5-6um. As a manufacturer in nano and super fine powders materials since 2002, would offer you high quality mateirals with favorable price and good service.

Si3N4 powder is available in beta phase and alpha phase, nano size and micron size, 99.9-99.99%.

The porous, high dispersion and high activity alpha aluminum oxide nanopowders apply to the nano ceramic material.

For the silver nanowires, we could not only supply powder form,but also could supply in dispersion, solvent could do it according to customer required.

Copper (I) oxide nanomaterial, Cuprous oxide nanoparticles, Dicopper oxide, Perenox,Mainly use: Biocide, Antibacterial agent, Antifouling primer, Catalyst, Superconducting materials, Photoelectric material, Sensor material, etc

Silver coated copper powder is mostly used for electromagnetic shielding for its good conductivity. Ag coated Cu powder for EMI shielding has good stability, excellent performance. Specification can be adjustable.

Silver coated copper powders can be customized to the required silver content by varying the grain size and shape.
