Description

ASTM B111 UNS C68700 / CuZn20Al2 / 2.0460 Aluminum Brass U Bend Heat Exchanger Tube

YUHONG GROUP is specialized in supplying heat exchanger tubes, boiler tubes and condenser tubes in China. The available materials we can offer including carbon steel, stainless steel, duplex steel, alloy steel, copper, nickel alloys, which can satisfy your different project rquirements. ASTM B111 C68700 / CuZn20Al2 / 2.0460 is a medium-cost, seawater-resistant aluminum brass ideal for U-bundle heat exchangers. Its key strength is resistance to impingement attack and dezincification due to aluminum and arsenic. Use it for clean to moderately polluted seawater or brackish water at velocities up to 3 m/s. Ensure proper post-bend stress relief and NDT (ET) to guarantee U-bend integrity.
