Brass Tube C68700 | Copper Alloy Tube--Aluminum Brass Tube

Copper Alloy Tube----Aluminum Brass Tube

 

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 th high resistance to impringement attack.

Aluminum Brass tubes are highly accepted and one of the extensively used material for various industrial applications.
