Characteristics
A Copper Zinc Alloy containing tin in small amount of arsenic, which is added as an inhibitor against dezincification. Inhibited Aluminium Brass resists the action of high velocity salt and brackish water and is commonly used for condenser tube. The outstanding characteristic of Aluminium Brass is the high resistance to impingement attack. Tubes of this alloy are recommended for use in marine and land power stations where cooling water velocity are high and where inhibited admiralty brass has failed from impingement

Guide to the selection of tube material
  • Sea Water
    • Dissolved salts more than from 2000 ppm
    • Suspended solids more than 30 ppm
    • H2S or Ammonia is less than 1 ppm
  • Permissible average velocity of water : 2.0-2.5 meters/sec.
