Galvanic Testing of Materials

Contact between dissimilar metals can lead to accelerated deterioration due to galvanic corrosion.  Standard sample Galvanic Series charts (e.g., ASTM G82) provide general guidelines for compatibility.  However, most of these charts are based on studies performed by the Navy for exposure to seawater submersion and do not include many of the available alloys and coatings used in building construction.  SGH is conducting ongoing, long-term testing on combinations of metals and metallic coatings to evaluate the severity of galvanic corrosion and the potential for staining.
