A reputable producer and supplier of Copper Nickel 90/10 Flanges, Harsh Flanges is based in Mumbai, India, and offers high-strength, corrosion-resistant flange solutions for industrial and marine applications. These flanges perform exceptionally well in brine and seawater environments because they are made of 90% copper and 10% nickel. At Harsh Flanges, we create flanges that satisfy international standards like ASTM B151 and B122 by combining meticulous quality control with precision engineering. Shipbuilding, offshore oil platforms, desalination plants, and other harsh settings needing long-term durability and dependability all make extensive use of our 90/10 flanges.
About 90% copper and 10% nickel make up Copper Nickel 90/10 Flanges. Tiny amounts of iron and manganese are added to improve corrosion resistance, particularly in saltwater. Excellent mechanical qualities are provided by these flanges, which have a tensile strength of approximately 310–350 MPa, a yield strength of 100–130 MPa, and an elongation of 30–40%. In turbulent waters, the alloy exhibits exceptional resistance to erosion, stress corrosion cracking, and biofouling. In marine environments, copper nickel 90/10 flanges are ideal for both bolted and welded flange connections because they retain their structural integrity over a broad temperature range.

Heat exchanger systems, desalination units, offshore platforms, shipbuilding, marine engineering, and power generation all make extensive use of copper nickel 90/10 flanges. They are perfect for seawater piping, cooling systems, ballast systems, and firewater systems because of their exceptional resistance to corrosion in brine and saltwater. Their thermal conductivity and stability under temperature fluctuations also make them useful in condenser and heat exchanger applications. Long-term, maintenance-free operation and less system downtime are guaranteed by the alloy’s anti-fouling qualities, which make it a preferred material for environments where marine growth and biofouling are issues.
