Reference national standard: electrolytic copper (GB/T467-1997)

product description:

The blister copper (containing 99% copper) is pre-made into a thick plate as the anode, the pure copper is made into a thin sheet as the cathode, and the mixed solution of sulfuric acid and copper sulfate is used as the electrolyte. After electrification, copper dissolves from the anode into copper ions (Cu) and moves to the cathode. After reaching the cathode, electrons are obtained and pure copper (also known as electrolytic copper) is precipitated at the cathode. High quality and can be used to make electrical products. According to the national standard GB/T467-1997 "Cathode Copper", the cathode copper is divided into high-purity cathode copper (Cu-CATH-1) and standard cathode copper (Cu-CATH-2) and two grades according to chemical composition.

Application range and purpose:

Electrolytic copper is a non-ferrous metal that is closely related to human beings. It is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields. It is second only to aluminum in the consumption of non-ferrous metal materials in my country. Copper is the most widely used and the largest in the electrical and electronic industries, accounting for more than half of the total consumption. Used for various cables and wires, windings of motors and transformers, switches and printed circuit boards, etc. It is widely used in the manufacture of vacuums, distillation pots, brewing pots, etc. in the chemical industry. In the construction industry, it is used as various pipes, pipe fittings, decorative devices, etc.
