Naval Brass

Why Naval Brass Is Preferred in Ship Manufacturing and Other Construction Projects

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. (more…)

Find Out Why Naval Brass Is Capable of Resisting Corrosion Caused by Salt

Did you know that the salt you put on your food and eventually into your system is capable of corroding metal? A compound of sodium and chloride, salt can quite be caustic on certain materials. You don’t have to worry, though, because your body does not respond similarly when in contact with salt. (Of course, like with any other food additive, you have to keep your salt intake in check to avoid problems) It’s just that metal and salt don’t mix well together. (more…)

The Conditions Causing Dezincification of Naval Brass and How to Avoid Them

Naval brass is widely used in marine construction due to its durability, corrosion resistance, and suitability to salt and freshwater settings. Brass is a popular material for propeller shafts, turnbuckles, and valve stems as well as many other marine fittings. However, sometimes, due to certain conditions, naval brass may experience dezincification, a kind of dealloying process wherein Zinc is removed from the alloy and leaves behind a copper-rich metal which is more porous. If you’re a boat maker, here’s what you need to know about the signs of dealloying Zinc, factors that can contribute to dezincification, and how you can prevent it. (more…)
