CHARACTERISTIC
 
A Copper Zinc Alloy containing tin and small amount of Arsenic that is added as an inhibitor against dezincification pressure of Tin imparts to the alloy good corrosion resistance in a moderately polluted river water and clean sea water, either stagnant or slow moving (up to about 2 meters/ sec.) and wrought form is tube for heat exchanger equipment.
