Q195 cathode flat steel is used for electrolytic aluminium factory, the low carbon steel has good electrical conductivity. To produce cathode collector bar of electrolytic aluminum is a strict process, because the electrowinning system is heavy DC current, the electroconductivity will decide the cost of Aluminum, so it must have very good electroconductivity, to save power consumption and raise the electrolytic efficiency.
