Naval Brass, as the name indicates, were originally developed for sea water service applications since it is a hard and durable material that provides excellent corrosion resistance, hot workability, and hot forgeability. Majority of the grades falling under Naval Brass are considered Lead Free products with Lead content around 0.20%. The usage of Naval Brass is not limited to Marine products, but also in bushings, valve stems, fasteners and wear strip because of its higher tensile strength and wear resistance properties. Tin is used in Naval Brass which slow down dezincification and can also control the rate of corrosion to allow acceptable practical service lives for marine products.
IS 219 Grade I Naval Brass is defined as per the Bureau of Indian Standards. This alloy contains higher Copper and Tin content when compared to IS 219 Grade II Naval Brass. This alloy offers excellent hot formability along with good corrosion resistance properties. They are widely used in marine construction where hard and strong material is required.
