Inhibited brass

WebbNaval Brass. Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, .75 percent tin and 39.2 percent zinc. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications. WebbFor example, inhibited brass is more resistant to dezincification than alpha brass, ductile iron is more resistant to graphitic corrosion than gray cast iron. Control the environment to minimize the selective leaching; …
