Dhruv Metals, a well-respected manufacturer and supplier located in Hyderabad, India, focuses on crafting top-notch Copper Nickel Flat Bars for a range of industrial and marine uses. Designed to comply with international standards like ASTM B151, these flat bars are celebrated for their remarkable corrosion resistance, strength, and ease of workability. Dhruv Metals provides these flat bars in both standard grades, such as 90/10 (C70600) and 70/30 (C71500), and custom dimensions with precise tolerances. With state-of-the-art manufacturing facilities and a strong commitment to quality, the company caters to clients in the marine, chemical, power, and engineering sectors worldwide.
Copper Nickel Flat Bars are typically available in 90/10 and 70/30 grades. The 90/10 alloy consists of 90% copper and 10% nickel, with added iron and manganese to boost strength and corrosion resistance. On the other hand, the 70/30 alloy has a higher nickel content, making it more durable in harsh environments. These bars showcase tensile strength ranging from 310–500 MPa, yield strength between 105–250 MPa, and elongation of 30–45%. They are renowned for their excellent resistance to seawater corrosion, biofouling, and stress corrosion cracking, along with good weldability, high thermal conductivity, and superior formability for fabrication.

Yes, Copper Nickel Flat Bars are customizable. They can be manufactured to specific dimensions, thicknesses, and lengths based on customer requirements. Additionally, they can be tailored for particular applications, such as varying alloy compositions or surface finishes, to meet performance needs in industries like marine, chemical, and power generation.
Copper Nickel Flat Bars find extensive use in marine, offshore, and shipbuilding sectors due to their exceptional resistance to saltwater corrosion and marine biofouling. They are perfect for seawater piping systems, structural supports, pump and valve components, and heat exchangers. In power plants and desalination systems, these bars are utilized for brine heaters, evaporator panels, and cooling systems. They also serve well in chemical processing equipment, hydraulic systems, and architectural features where durability and corrosion resistance are essential. Their smooth finish and formability make them ideal for both structural and decorative applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
