Product Description

C68700 Aluminum Brass

UNS CDA101, ASTM B187, ASTM B152, CuZn20Al2As

The C68700 Aluminum Brass contains small amount of arsenic and can also be added as inhibitor against dezincification. The aluminum brass is mainly used while manufacturing the condensor tubes as these stops the action causes by brackish water and high velocity salts. The metal alloy is resistant to impingement attack and the tubes are also recommended for using in power stations.

Typical Uses for C68700 Aluminum Brass "Arsenical" :

Industrial: Condenser Tube, Evaporator Tubes, Ferrules, Distiller Tubes, Heat Exchanger Tubes
