Admiralty Brass Tube C44300
Admiralty Brass is an Copper Zinc Alloy, and contains small amount of tin and arsenic as well. These admiralty brass tubes are renowned for their characteristic of superior corrosion resistance in a moderately polluted river water and clean seawater, both stagnant or slow moving water. The most common and wrought form is tube for heat exchange equipment. These tubes are extensively used in various applications including; evaporators, condensate coolers, heaters, vent condensers, water heaters, generator, air coolers, turbine oil coolers for petrochemical, ship-building, power plants, desalinations plants etc.
