Product Description

ASME SB111/ASTM B111 C68700/CuZn20Al2As,HAL77-2 seamless copper alloy condenser tube
Inhibited Aluminum Brass tubes – C68700 - resists the action of high-velocity salt and brackish water and is commonly used for condenser tubes. The main characteristic of C68700 is its high resistance to impingement attack. Tubes of these alloys are recommended for use in Marine and Land Power Stations, in which cooling water velocities are high.
