Aluminum has quickly become the material of choice for protecting boats from corrosion. This is for a few different reasons. Aluminum alloys are lightweight and superior when it comes to boating in saltwater and brackish water. Studies have shown that aluminum anodes may last up to 50% longer than their counterparts when exposed to the compounds found in salt water.
In addition to being more effective, aluminum is also better for the environment. This is because the activators used in aluminum anodes are comprised of safer materials. People who use their boats in a wide variety of environments are likely to get the best bang for their buck from aluminum anodes. This is due to its efficiency in both salt and brackish water.
