Characteristics:

A Copper Zinc Alloy containing tin and small amount of arsenic which is added as an inhibitor against dezincification. The 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 mtrs/sec.) . The most common and wrought form of tube is tube for heat exchange equipment.

Guide to the selection of tube material:

Clear, river, Lake or canal Water. 

a) Dissolved salts more than from 2000 ppm . 
b ) Suspended solids more than 25 ppm . 
c) H2S or Ammonia is less than 1 ppm . 
d) Choloride less than 20 ppm 
e) For temperature more than 200*** C and less than 450**** C 
Permissible average velocity of water 2.0 – 2.5 meters/sec.
