METAL ANODES

Metal anodes are diffferent grades of high specification metals for particular applications with unique metallurgy that are used in electrochemical processes like electroplating or marine corrosion protection. Many different metals are used such as aluminum, zinc, magnesium, titanium, tin, cadmium, lead, copper, or various alloys such as bronze and brass.  Different metals are chosen as anodes for various reasons. For example, some metals are more ductile than others, while some have superior strength.

There are two main uses of metal anodes: one for marine application and the other for plating. Sacrificial anodes are used for corrosion protection.  These anodes are chosen because the metal of the anode is more easily corroded than what you are trying to protect. Electrons that are removed from the sacrificial anode are transferred to the protected metal so that it becomes a cathode.  The extra electrons allow reduction to occur on the surface of the protected metal rather than corrosion.  Today, sacrificial anodes are commonly available in aluminum, magnesium, and zinc. Aluminum is lightweight and last 50% longer in saltwater than zinc and works in both salt and brackish water.  Magnesium is the best anode to use in fresh water.  It does not perform as well in salt water.  Traditional Zinc works well in salt water, however it is heavier and more toxic to the environment.

Metal Anodes can be used mainly for plating and electroplating applications.  Electroplating is a special process for plating that uses electrical current to facilitate the coating process. Plating is used to decorate objects, for corrosion inhibition, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for radiation shielding, heat resistance and other purposes.
