C70600 Blind Flange and 90/10 Cuni Flange Manufacturer in India
Both copper and nickel are metals that can be easily alloyed with each other. In the form of an alloy, they offer the end user multiple advantages. High ductility and malleability, good strength with good resistance to corrosion. Copper Nickel Flanges are mainly used in applications involving the sea because they can withstand highly saturated saltwater or brine solutions at various temperatures.
The content of nickel used to alloy them enables them to show their tolerance to elevated temperatures, making the Copper Alloy 70/30 WNRF Flange an ideal component for marine engineering projects. Amongst all copper nickel alloys, the two most common grades would be CuNi 70/30 and CuNi 90/10. As their name suggests, the grade of these alloys takes after their chemical composition, with the first number indicating the content of copper and the latter would be the content of nickel. C70600 Industrial Flanges have an added content of 1.4% ferrous in their alloy, giving them resistance to several corrosion-related issues such as erosion, impingement as well as general corrosion. The presence of nickel in grade 90/10 Copper Nickel Flanges is lower, making it suitable for those applications where the temperatures would be moderately high. Moreover, the ductility of this alloy is higher than grade 70/30. This grade also acts as a substitute for 70/30 CuNi, becoming a cost effective option across several industries. While both nickel and copper are commodity metals, the trading price for nickel is significantly higher than copper. Hence grade Cu Ni 70/30 Flanges tend to be much more expensive than grade 90/10 CuNi. With the increase in nickel in its alloy, the corrosion resistance properties also witness a leap. These properties are suited to participate in highly demanding applications, especially if the grade 70/30 cupro nickel flange is to be used in polluted or high velocity marine waters.
