If you want to know what is Copper Nickel Plate, then as the name suggests, it is a plate which is made up of an alloy of copper and nickel. Due to its chemical composition, the Cuni plate has high resistance to seawater. This is why they are widely used in seawater equipment as they can totally resist barnacle growth, by the formation of a thin layer of tenacious protective film.
The Copper Nickel Sheet is also used in hydraulic tubing and brake tubing. The Cupronickel Sheet can be found in important equipment like seawater cooling, firewater systems, etc. As they show good performance at a high temperature and pressure, the Copper Nickel Alloy Sheet is also an eminent part of heat exchangers and condensers. They can also be found in the cast seawater pumps and various valve components.
The hardness of Cupro Nickel Plate is lesser than the stainless steel plates, which means they are much more flexible. One can easily create forms and flares with Cupro Nickel Sheet for repairing, and unlike stainless steel, these are easy to work with. As the Cupro Nickel Sheet can be bent and flared easily, hence they are capable of creating a tighter seal.
There are several features of Copper Nickel Sheets which make them ideal for several applications and hence popular among different industries.
Sunflex Metal are leading Copper Nickel Sheet suppliers in India. Copper Nickel Plate and Foil chemical composition is 8.5 to 45% Ni, but so as to improve their specific properties, almost all commercial alloys of Copper Nickel Coil, also contain tin, iron and manganese. The Molecular Formula of Copper Nickel Strip is CuNi. The Machinability of Cupro Nickel Sheet (based on free-cutting brass = 100) is 20. Cuni Foil has an Elastic Modulus (C71500 annealed) of 22000 ksi (152 GPa). Cuni Sheets are used in a large number of industrial projects such as process equipment, fresh water preparation, condensers, solder frames, electrical resistors, oil coolers, housings for electrical sub-assemblies, propeller sleeves, refrigerators and heat exchanger components.
An alloy of Cupro Nickel Plate, CuNi30Fe2Mn2, is ideal for use for abrasive liquids, such as in dredgers. Cupro Nickel Coil melting point is 1171 °C (2140 °F). Cuni Strip has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). The Elongation at Break (annealed), is 40%. It has a Density of 0.323 lb/in³ (8.94 g/cm3). The Poisson’s Ratio of Cupro Nickel Strip (C71500 annealed) is 0.325. Other designations of equivalent materials to Cupro Nickel Foils are ASTM B552, ASTM B543 and ASTM B111. Since many decades now, products made from Coppernickel have proved to be very reliable. Today, in a world confronted with all kinds of technological advances and challenges, Copper Nickel Plates still proves to be very trustworthy, providing all kinds of highly effective solutions. These Copper Nickel Sheets & Plates are also in big demand in electrical engineering for plug connectors, relays, light-current switches and sprung contacts. Sheet made from Copper nickel are also used in offshore fire water systems, cabled tubes for pneumatic lines, hydraulic lines, feed-water heaters, etc.
