Cuni Hex Bar and Copper Nickel Rod supplier in Mumbai
Copper nickel or cupro-nickel round bars are specifically designed to work across different seawater applications. A Copper Nickel Round Bar is designed with a circular cross-sectional area. These bars provide support and stability to different systems in structural applications. The Cupro Nickel Round Bar possesses high strength and showcases enhanced corrosion and oxidation resistance properties across harsh environments. A Copper Nickel Rod is a thin straight bar that is very versatile and has enhanced malleability and possesses a good surface finish. The Cupro Nickel Rod has an excellent melting point and can be produced in square, round, rectangular and hexagonal shapes. A Copper Nickel Hex Bar is designed via a hexagonal cross-section. The unique bar is fixed with bolts and screws or can be welded securely. The Cupro Nickel Flat Bar is designed with a rectangular cross-sectional area. These flat bars possess good strength and toughness. The case hardened bar has good weldability and ductility. A Cuni Square Bar has a square cross-sectional area. These bars are seen in general assembly or manufacturing units. They are also seen in repairs and ornamental applications.
A Copper Nickel Forged Bar is produced at extreme pressures giving the bars enhanced strength. These bars have a finer grain structure and possess lower surface porosity. We use the best Copper Nickel Bar Stock raw materials that are utilized in metalworking and manufacturing systems. These stocks are available in a wide spectrum of sizes to meet different customer requirements. Our institution is amongst the top echelons of Copper Nickel Round Bar manufacturers in India who have a vast stock of inventory of stock that can suit different industries.

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 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.
