contact2023117 · The corrosion inhibition of the phytic acid on HAl77-2 brass was significantly increased with the addition of sodium molybdate. Besides, the synergistic action of phytic acid and sodium molybdate can weaken the dezincification of brass obviously. These results provide theoretical support for the application of the self-assembled
contactAluminum Brass tubes – C68700. 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.
