CHARACTERISTIC
 
A Copper Zinc Alloy containing tin and small amount of Arsenic which is, added as an inhibitor against dezincification. Inhibited Aluminum Brass resists the action of high velocity salt and brackish water and is commonly used for condenser tube. The outstanding characteristics of Aluminum Brass are the high resistance to impingement Attack Tubes of this alloy are recommended For use in marine and land power stations where cooling water velocities are high and where inhibited admiralty brass has failed Impingement
 
Guide to the selection of tube material:
ww
  Sea Water: -
a. Dissolved salts more than 2000 ppm
b. Suspended solids more than 30 ppm
c. H2C or Ammonia is less than 1 ppm
d. Permissible average velocity of water 2.0-2.5 miters/sec.
 
TEST:
ww
  Drift test, Flattening test, Mercurous nitrate test, M.N test, Eddy current test as per specification.
