Plating<\/span> anodes<\/span> are, in fact, made of <\/span>lead alloys<\/span> of different compositions for greater conduction of electricity and <\/span>corrosion resistance<\/span>. Each type of <\/span>lead anode<\/span> has benefits that make it suitable for different applications.<\/span><\/p>\n

Lead anode<\/strong><\/a> alloys<\/span> generally consist of tin, silver,<\/span> and antimony<\/span>. The favored alloys, based on the specific application, are lead-<\/span> antimony<\/span> tin as well as lead-silver alloys. One reason for this is because of the alloys\u2019 resistance to corrosion in the sulfuric acid that\u2019s used for electrolytic solutions. (Lead-alloy anodes are used in electro winning \u2013 also known as electro extraction \u2013 as well as for plating metals such as manganese, copper, nickel, and zinc.) <\/span>Lead anodes have superior attributes, such as being highly resistant to the corrosive effects of seawater. <\/span><\/p>\n

The ongoing demands for continuous improvement in the <\/span>plating <\/span>industry has led to changes in the manufacture of lead anodes. In addition to various lead alloys, different <\/span>formats<\/span><\/i> of lead anodes are manufactured for different purposes. For example, in the effort to improve plating processes, plating operations have increasingly made the move from rectangular and\/or flat anodes to solid round anodes. <\/span><\/p>\n

Round anodes have an active electrical surface around the anode\u2019s entire perimeter. This is advantageous because it means less voltage is required to carry the electrical current. As well, more amperage can be carried without disproportionate heating. Furthermore, round anodes do not have \u201cdead spots\u201d where there is no electric current; a problem that would otherwise result in the shortened life span of the anode. This is just one example of a preferred format that offers a longer lifespan with more assured electrical efficiency. <\/span><\/p>\n

Lead anodes<\/a><\/strong> can be manufactured in formats to suit different purposes. This is one of the areas of expertise of Canada Metal North America (CMNA), which manufactures lead anodes in various formats and of different alloys to suit specific client requirements and applications.
