Spherical Copper Powder

Flake copper powder

Silver Coated Powder

 
Spherical copper powder is an ultra fine metal powder with a high dispersibility, high filling nature, And uniform particle size. Because it excels in dispersibility and adheres well to resin and solvents, this product makes it possible to shorten the necessary mixing time and to achieve a high degree of product uniformity.

Flake copper powder is an ultra fine metal powder with a highdispersibility, high filling nature,And uniform particle size. When the ultra fine copper powder, with a uniform particle diameter, isFlaked, the resulting shape gives the powder excellent conductivity characteristics, making itAppropriate for use in conductive paste.
