Admiralty Brass Tubes is specially used for its tubing applications. It is a copper-zinc alloy containing a small amount of arsenic and tin as well. This material has excellent resistance properties in the sulphur compound and contaminated water. It is used for supplying seawater, polluted river water, and freshwater. Admiralty Brass Tubes has good corrosion resistance quality, which makes them suitable to use in various environments. This makes it durable and works correctly in many complex industrial applications.Our high-grade Tubes has excellent ductility, conductivity and also withstand higher temperature. It offers versatility fittings in a variety like pluming, connecting small networks, and many more. Our precise Admiralty Brass Tubes has numerous beneficial features which are suitable t use in steam condenser cooled, brackish water, marine appliance, heat exchangers in refineries. These Tubes are also demanded to use in petrochemicals and power plants. Admiralty Brass Tubes is available in different sizes and specifications.
