Admiralty Brass Tube
Admiralty Brass Tube is a copper zinc alloy, and contains small amount of Tin and Arsenic.
These Admiralty Brass Tubes are renowned for their characteristic of superior corrosion resistance in a moderately polluted river water river water and clean seawater, both stagnant or slow moving water.
The most common and wrought form is tube for heat exchange equipment.
