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.
