Dendritic Copper Powder

electrolytic-Cu-PMS1-38-e1415010753690

Dendritic copper powders are manufactured by an electrolysis process and are often referred to as electrolytic copper powder or ECP. They are available in various grades offering differing particle size, specific surface area, apparent density and morphology.

Our dendritic copper powders are available with low, medium and high apparent densities. The powders offer good green strength, high compressibility, excellent electrical conductivity and have very low lead (Pb) levels and low oxygen content.

Typical applications include use in friction components, conductive oils and greases, cold casting, cold metal spraying, welding and brazing, diamond tooling, anti-fouling paints, electronics and electrical contacts and in combination with iron powder to improve properties of sintered parts.
