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. 

Nano Aluminum Powders have small size effect and it works well for corrosion resistance in coating. Besides corrosion protection in coating, Al nanoparticle can improve mechanical properties also.

Amorphous nano boron powders is brown black powder, high purity, widely used in metal refining.

α-phase nano-alumina powder is spherical, high purity 99.99%, widely used in ceramic materials.

Our high thermal conductivity aluminum nitride nanopowders is widely used in ceramic substrates.

Hongwu High active iron nanoparticles(20nm-100nm) is widely used in absorbing materials.

If you want to buy nickel powders including spherical nickel,flake nickel,Spiny spherical nickel, nickel nanowires and nano nickel alloy powders, please turn to Hongwu Nanomaterial, We pay special attention to the quality assurance of nickel particles and services we deliver.

The general purity of Hongwu's MWCNT is 99%. If not high requirements, lower purity about 90%+ one is also available. For some application, low purity MWCNT would be more cost-effective.
