Which material is not commonly associated with galvanic corrosion?

Galvanic corrosion occurs when two dissimilar metals come into contact in the presence of an electrolyte, leading to an electrochemical reaction that results in the deterioration of one of the metals, typically the one with a lower corrosion potential. Materials that are commonly involved in galvanic corrosion are usually metals or metal alloys.

Glass, being a non-metallic and insulating material, does not participate in galvanic reactions. It has a stable chemical structure that does not readily develop electrical conductivity needed to contribute to galvanic corrosion processes. In contrast, metals like copper, aluminum, and stainless steel are all conductive and can easily form galvanic couples when in contact with other metals, especially in environments where moisture or electrolytes are present. This distinction is crucial to understanding the conditions under which galvanic corrosion can take place, making glass the clear choice as a material not typically associated with this phenomenon.
