ASTM B515 UNS C70600 copper nickel flanges are corrosion-resistant flanges made from 90/10 copper-nickel alloy, widely used in marine, offshore, and heat exchanger applications. These flanges offer excellent resistance to seawater, biofouling, and stress corrosion cracking. Common types include weld neck, slip-on, blind, and plate flanges manufactured as per ASTM B151 copper flanges and ASME standards
When it comes to reliable performance in harsh environments like seawater systems, offshore platforms, and desalination plants, copper C70600 flanges are one of the most trusted solutions. These flanges, also known as copper nickel 70 30 flange and ASTM B151 Cu Ni 90 10 flanges , are designed to offer long service life, minimal maintenance, and excellent resistance to corrosion.
We manufacture and supply a wide range of ASTM B515 UNS C70600 copper flanges, tailored to meet industrial piping requirements across marine, oil & gas, power, and chemical industries. With strong technical expertise and real-world application experience, we ensure that every flange meets international quality and performance standards.
What are Copper C70600 Flanges?
C70600 flanges are made from a copper-nickel alloy containing approximately 90% copper and 10% nickel, along with small additions of iron and manganese for enhanced strength.
These flanges are produced according to standards like:- ASTM B151 copper flanges
- ASTM B515 UNS C70600 copper flanges
- ASME B16.5 / B16.47
They are commonly used in systems where corrosion resistance and durability are critical, especially in saltwater environments..
Benefits of Copper C70600 Flanges
- Excellent Corrosion Resistance: Performs exceptionally well in seawater and chemically aggressive environments.
- High Strength: Stronger than many other copper alloys, making it suitable for high-pressure applications.
- Long Service Life: Resistant to wear, fatigue, and stress cracking.
- Low Maintenance: Minimal maintenance required due to its durability.
