Copper Nickel 90/10 Flanges

Copper Nickel 90/10 flanges are a specific combination of metals offering superior corrosion resistance and strength. The material mixture is composed of approximately 90% copper and 10% nickel, with the remaining percentage being made up of iron, manganese, and other metals. Copper Nickel 90/10 flanges offer excellent resistance to pitting, crevice corrosion, erosion-corrosion, and stress cracking in acidic environments, making them ideal for usage in offshore oil rigs, desalination plants, power generation facilities, and chemical processing plants. This robust material also offers superb machinability properties allowing for easy workability with hand tools. As such, it is the ideal choice for many piping applications when stringent welding requirements must be met.

90/10 Copper-Nickel Flanges, also known as UNS C70600 or CuNo30Ni Flanges, are ideal for use in severe stress impact and environmental conditions. Perfect for shipbuilding and other marine environments, as well as various industrial applications, these flanges have superior corrosion resistance to seawater, brine solutions, and many other corrosive materials. Additionally, Copper-Nickel 90/10 Flanges offer incredible strength and toughness needed for extreme conditions such as boilers and pressure vessels. They can even be used in high-temperature settings up to 600 degrees Fahrenheit with superior formability for various fabrication techniques. Their strength is further enhanced when cold worked through such techniques as spinning or press forming, making them highly customizable for multiple uses.
