Description
Cupro Nickel Bar is an alloy of copper that contains nickel and other strengthening elements such as iron and manganese. The addition of copper and nickel alloy in the right amount makes it a superior quality product. Due to its superior quality it has become very much high in demand.
Copper Nickel Flat Bar is a kind of metal product bearing rectangle section. It is used in a wide range of structural and architectural applications. It can only be hardened by cold working. It has high corrosion resistance together with resistance to corrosion fatigue.
Cupro Nickel Round Bar resists corrosive and erosive actions of rapidly moving seawater. The corrosion resistance of it increases with increasing nickel content. Copper Nickel Round Baris a long, cylindrical copper nickel bar stock that has many industrial and commercial applications and the most common application includes shafts. Cuni Round Bar is moderately hard also but tough and ductile. Cupronickels rods with 10 and 30% nickel are very commonly employed for condenser, distiller, evaporator, and heat exchanger tubes. The common heat treatment applied to it is annealing after cold working. It is highly resistant to corrosion by salt water, and hence it is useful for heat exchangers and condensers in seawater systems.
Copper Nickel Round Bar is also known as cupronickel round bar which is widely used for marine applications due to its good fabricability, excellent resistance to seawater corrosion and low macro fouling rates.
