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.
C48500 Naval Brass alloys is also referred as High Leaded Naval Brass noted for its machinability and resistance to wear, fatigue, galling and stress corrosion cracking. Due to the presence of higher percentage of lead, this alloy has poor cold forming ability. C48500 is suitable for valve stems, machined bearings and marine hardware products.
