Unlike other types of vehicle, sea vessels face one unique, tough challenge–saltwater corrosion. There’s a vast range of substances that can corrode metals, but sodium chloride or salt, mixed with water and other impurities, is different. Saltwater can cause most metals to corrode five times faster than freshwater. Even well-known corrosion-resistant metals like copper, bronze, and aluminum don’t stand a chance against this potent chemical soup. This is why most boats and ships are not expected to last long without regular maintenance and coating.
Thanks to advancements in metallurgy, alloys that have better saltwater corrosion resistance have been discovered and are now widely used in ship construction. One of these alloys is naval brass, a perfect mix of copper, zinc, and tin. It is primarily designed to improve the performance of the outer covering of ships.
