What Does Lead Silver Alloy Mean?

Lead silver alloy is a lead-based alloy that falls in the category of L50100 – L50199 per the Unified Numbering System (UNS) that is managed jointly by ASTM International and SAE International. Lead silver alloys are primarily used as anodes in the electrowinning and plating of metals such as manganese, copper, nickel and zinc.


Corrosionpedia Explains Lead Silver Alloy

Lead silver alloy is used to prepare anodes that are then used in the electrowinning and plating of metals because they exhibit high corrosion resistance in the sulfuric acid used in electrolytic solutions. These alloys also exhibit high resistance to corrosion by seawater, which makes them a preferred and economical material used by systems for the cathodic protection of ships and offshore oil rigs.

The production of complex shaped anodes is possible because lead is very soft and ductile. They are sometimes used in car batteries.
