DIN17660 CuZn20Al2 F39 Copper Alloy Steel Heat Exchanger Tube For Chemical Processing

DIN 17660 CuZn20Al2 F39 Copper Alloy Heat Exchanger Tube refers to a brass alloy composed primarily of copper (Cu), zinc (Zn), and aluminum (Al), specifically designed for use in heat exchanger tubes. This alloy is characterized by its combination of strength, corrosion resistance, and thermal conductivity, making it ideal for applications in marine, industrial, and HVAC systems. The alloy's designation (CuZn20Al2) indicates the specific composition: approximately 20% zinc and 2% aluminum by weight, with copper making up the balance.

Chemical Composition:

Key Features:

• Corrosion Resistance: Strong resistance to seawater corrosion and dezincification.

• Biofouling Resistance: Inhibits the growth of marine organisms.

• Thermal Conductivity: High for efficient heat transfer.

• Strength and Durability: Good mechanical strength and erosion resistance.

Applications:

1. Marine Heat Exchangers: The alloy’s resistance to seawater corrosion makes it ideal for use in marine heat exchangers, particularly in cooling systems aboard ships, offshore oil rigs, and submarines.
2. Cooling Systems in Power Plants: Used in seawater-cooled heat exchangers in thermal and nuclear power plants, where the combination of corrosion resistance and thermal conductivity is critical.
3. Desalination Plants: CuZn20Al2 is often used in desalination systems, where corrosion resistance to salty water is crucial. The alloy can be used in reverse osmosis (RO) or multi-effect distillation (MED) processes.
4. Industrial Heat Exchangers: This alloy is commonly found in heat exchangers for various industrial applications, including chemical plants, petrochemical facilities, and refineries, due to its durability and resistance to aggressive fluids.
5. Refrigeration and HVAC Systems: CuZn20Al2 is used in industrial refrigeration and air conditioning systems, especially in coastal regions where the presence of salt and humidity could lead to corrosion in other materials.
