Copper Cathodes

Sunholly has carried out global trade cooperation in electrolytic copper products, and established long-term and stable trade partnerships with world-renowned companies, providing fast and high-quality services to the majority of copper-using companies.
The surface of the cathode copper should be clean and free of foreign debris such as sludge, oil, and electrolysis residues.
On the cathode copper surface (including the lugs), the total area of green attachments shall not exceed 1% of the single-sided area.
Due to the action of moist air, the surface of the cathode copper is oxidized to form a dark green layer, which is not a waste product.
There should be no petal-like or dendritic grains on the surface and edge of the cathode copper (repairing is allowed).
The total area of the round head dense grains on the surface of the cathode copper above 5mm shall not be greater than 10% of the single-sided area (repairing is allowed).
Total content of impurity elements (%)≤0.0065
Comply with the new version of the national standard GB/T467-2010 Class A copper (Cu-CATH-1) standard

Uses: Mainly used in the manufacture of cables, electrical components, pipes, copper alloys, and raw materials for bearings, pistons, high-voltage equipment, aircraft and naval parts, building materials, cooling devices, packaging materials, etc..
