Copper Electrowinning lead (Pb)Alloy Rolled Anode

 

Pb alloy anode is widely used in Zinc, Copper, Nickel, Cobalt and Manganese EW industry for its inent property low production cost .

Pb alloy rolling plate, with uniform crystal structure, is better in anti-corrosion and  mechanical performance stability. 

The hanger bar which is certain mm thickness Pb cladding around Sn electro-plating on copper bar, has better anti-corrosion to acid mist during electro-winning. 

Pb plate connects to hanger bar through two-side welding with Pb cladding, or plate plug-in welding.

 

Advantages

High mechanical strength against warpage and creep (form stability), no casting defects and porosity

Low oxygen over potential for oxygen evolution

Quick and stable formation of hard, compact and adherent protective corrosion layer (conditioning)

High corrosion resistance, higher resistance to initial conditioning, long service life.

Minimized production cost

Reduction in cell voltage, increase in current efficiency

Production of high quality lead free metal cathode product

No anode or cell cleaning required

Elimination of cobalt addition required in Zn/Cu/Co/Mn electro-winning

After assembly, flat smoothing blank surface, vertical to horizontal level, blank flatness error ≤ 0.2 mm
