C71520 Material Properties

C71520has added iron and manganese for excellent corrosion and biofouling resistance in fresh and sea water. Alloys with nickel content higher than 90/10 copper-nickel have enhanced mechanical properties while still maintaining excellent corrosion resistance.
In clean seawater, the alloy accepts water flow rates as high as 2.2-2.5%/s. The maximum acceptable speed in brackish solutions is up to 4m/s. The alloy avoids stress corrosion cracking and denickeling at high temperatures. Therefore, the alloy has good corrosion resistance to clean or polluted seawater and Jiangwan water, and is widely used in heat exchangers using seawater such as power stations, seawater desalination, and petrochemical plants.

Advantages

1. High resistance to corrosion in seawater
2. Excellent resistance to biofouling and erosion
3. Good mechanical properties
4. Superior weldability and fabrication
5. Long service life in marine environments
6. Low susceptibility to stress corrosion
7. Cost-effective compared to alternative alloys
8. Resistant to pitting and crevice corrosion
9. Good thermal stability at elevated temperatures
10. Versatile for various marine applications

Application areas of C71520 material

C71520 cupronickel is widely used in shipbuilding, petrochemical, electrical appliances, instrumentation, medical equipment, daily necessities, handicrafts and other fields due to its excellent corrosion resistance and easy molding, processing and welding in copper alloys. As a corrosion-resistant structural member, it is also an important resistance and thermocouple alloy. On heat exchangers using seawater such as power stations, seawater desalination, petrochemical plants, etc.
