DIN 17660 Aluminum Brass tube CuZn20Al2 F39 Copper Alloy Seamless Tube for Heat Exchanger / Condenser

 

 

Aluminum Brass tubes – CuZn20AL2/C68700 - resists the action of high-velocity salt and brackish water and are commonly used for condenser tubes. The main characteristic of CuZn20AL2/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.

 

The aluminium brass tubes are basically a combination of high strength as well as general corrosion resistance with low susceptibility having stress corrosion cracking, making it a highly preferred material for different types of applications. The tubes can also be used in hard drawn conditions and can be heat treated which in turn ensures freedom from the stress corrosion cracking.
