Cathode copper

Product name: copper plate

Applications: it is mainly used for wires, electricity, machinery manufacturing and military industries among others. With good mechanical properties and machinability, it can withstand high and low temperature pressures during the processing and is a suitable material for cutting and stamping processing to obtain certain structural parts, such as gaskets, bushings and so on. The brass plate possesses high corrosion resistance, good mechanical properties and good workability in both high and low temperature states. It can be used for obtaining steam-corrosion resistant parts on ships, oil medium contact parts and conduits

Electrolytic copper

Crude copper (99% copper-pure) is prefabricated into a thick-plated anode, and pure copper is processed into a thin sheet serving as the cathode. A mixed solution of sulfuric acid (H2SO4) and copper sulfate (CuSO4) is used as electrolyte. When in an energized state, the copper of the anode is then dissolved into copper ions (Cu2+). The copper ions proceed to the cathode where they obtain electrons and then precipitate into a product of pure copper (also known as electrolytic copper). In the process, impurities contained in the crude state such as active iron and zinc will be dissolved in ions (Zn and Fe). Because these ions are not easy to precipitate compared with copper ions, their precipitation in the cathode can be avoided as long as the electrolyzing process is adjusted to properly take the differences into account. Other impurities which are less active than copper such as gold and silver will deposit on the bottom of the cell. Copper plate produced in this way is characterized by its high quality and can be used to produce electrical products.

Electro-deposited copper

The non-ferrous metal copper is closely related to human life, due to being widely used in electrical and light industries, machinery manufacturing, construction and defense industries among other fields (this has already been mentioned in the part “Applications” of “Copper Plate” -two paragraphs up-, there is no need to mention it again if on the same webpage). It ranks second in terms of consumption -after aluminum- amongst nonferrous material. The electrical and electronic industry represents the largest share, accounting for more than half of the total consumption. Copper can be used for the production of a variety of cables, wires, winding of power motors and transformers, switches and printed circuit boards, etc. In the manufacture of machinery and transport vehicles, copper can be used to make industrial valves, accessories and instruments, sliding bearings, molds, heat exchangers, pumps and so on;In the chemical industry, copper is widely used in the manufacture of vacuums, distillation pots, brewing pots and so on; And in the defense industry, it can be transformed into bullets, shells, gun parts and so on.
