What types of metals will not galvanize?
There are many types of materials that will not develop a galvanized coating. Iron is necessary for a galvanizing reaction to happen, so if you try galvanizing copper or aluminum, they will not develop a galvanized coating. 400-series stainless steel will not develop a galvanized coating either. Some types of chrome-moly steels can develop a galvanized coating, but will have many bare areas.
