ASTM B171 Copper Nickel Plate
Copper Nickel Plate ASTM B171/ SB 171 UNS C70600 4feet x8feet
Copper Nickel Plate 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.
- They are highly resistant to seawater corrosion and biofouling.
- They can resist chlorides in terms of pitting, stress corrosion cracking and crevice corrosion, even at a higher temperature.
- They possess good thermal conductivity.
- They are highly ductile.
- They are able to maintain their performances at higher temperatures.
- They have antimicrobial properties and hence can be used for healthcare applications.
- The Copper Nickel Strip can be customized according to the requirements given by the clients.
- Their shape, size, dimensions, and surface finishes are made according to the application needs.
