Admiralty Brass Alloys Tubes – resists the action of high-velocity salt and blackish water and is commonly used for condenser tubes. The main characteristic of C68700 is its high resistance to impingement attack. Tubes of this alloys are recommended for use in Marine and Land Power Stations, in which cooling water velocities are high.
