Overview
ASTM B111 C68700 Aluminum Brass tube, UNS CDA01, ASTM B111, ASTM B395, ASTM B187, ASTM B152. ASTM B111 C68700 has especially good corrosion resistance properties in sea water. Aluminum Brass Tube is a copper zinc alloy containing aluminum and small amount of arseric which is added as an inhibitor against dezincification. Inhibited Aluminum Brass resists the action of high velocity salt and brackish water and is commonly used for condenser tube. The outstanding characteristic of Aluminum Brass is the high resistance to impringement attack. Aluminum Brass tubes are highly accepted and one of the extensively used material for various industrial applications.
