Sunflex Metal is India's leading manufacturer and supplier of Copper Nickel Bar. Cupro Nickel Round Bar composition is that of copper and nickel, to which iron and manganese have been added, as agents of strength. Cuni Bar has a Tensile Strength (annealed) of 52000 psi (359 MPa) and it has a Tensile Strength (rolled-H04 for flat products/ hard drawn-H80 for tubing) of 78000 psi (538 MPa). Cupro Nickel welding rods has a Shear Modulus (C71500 annealed) of 8300 ksi (57.2 GPa). Copper Nickel Bar is in big demand in applications like electrical resistors, tube mounting material, terminals, control and load resistors, heating elements and in thermocouples. Binary Copper Nickel Alloy Rods are used along with materials that have been alloyed with iron and manganese, in automobile construction, metal goods industries, measuring instruments, aircraft construction and sheet goods industries.
Copper Nickel Round Bar has a Rockwell B Hardness of 69. The Poisson’s Ratio of Copper nickel (C71500 annealed) is 0.325. The Elongation at Break of Cuni Round Bar (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Thermal Expansion Co-efficient of Copper Nickel flat bar (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). Cuni round rod has a Thermal Conductivity of 32.9 W/mK (0.0900 BTU in/hr.ft². °F). Cupro Nickel hexagon bar uses are many, as due to copper being added to nickel, the corrosion resistance and strength of copper is increased. As such, Coppernickel Bar offers fantastic resistance to corrosion from seawater and it also has low macrofouling rates and so it finds immense use in marine applications. Bars made from Copper Nickel round rod are used in plates, seawater lines, heat exchanger bases and tubes.
