Product Details

BS2871 CZ110 Copper and Copper Alloys Seamless Round Tubes for Heat Exchangers

Aluminum Brass tubes – CZ110 - resists the action of high-velocity salt and brackish water and are commonly used for condenser tubes. The main characteristic of CZ110 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 aluminum 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.

Typical use	Most used copper alloy for heat exchanger tubes application. Represents the best option for any heat exchanger which is involved with saline water. The addition of arsenic has solved the problem of dezincification. Melting Point: 935°C • Hot Working Properties: OK Density (20°C): 8,33 g/cm3 • Cold Working Properties: Very Good
Weight Formula	Average Wall: (OD-WT) x WT x 0,0265 = Kg/m (all sizes in mm) Minimum Wall: (OD-WT) x WT x 0,0275 = Kg/m (all sizes in mm)
