Top Lead Alloy Anodes

We are ranked amongst one of the most promising manufacturing, exporting and supplying units ofA Top Lead Alloy Anodes in Chennai, Tamil Nadu, India. The anodes made of Lead Alloys are used in the electro winning and plating of metals such as manganese, copper, nickel, and zinc. Rolled lead-calcium-tin and lead-silver alloys are the preferred anode materials in these applications, because of their high resistance to corrosion in the sulfuric acid used in electrolytic solutions. Lead Anodes also have high resistance to corrosion by seawater, making them economical to use in systems for the cathodic protection of ships and offshore rigs. Lead, alloyed with 1-2 % silver and 6 % antimony is also used as an impressed current anode for seawater applications and operates at up to 24 V DC. The alloy naturally forms an insulating film of lead chloride when immersed in seawater, however this can be converted to a conducting layer of lead peroxide by operating the anodes at carefully controlled current densities.
