Copper Nickel Alloy C70600 / C71500 Products — Frequently Asked Questions
Copper Nickel Alloys C70600 (commonly known as Cu-Ni 90/10) and C71500 (Cu-Ni 70/30) are copper-based alloys with primary additions of nickel, iron, and manganese. They are highly valued for their exceptional resistance to corrosion, erosion, and biofouling in seawater and brackish water, making them ideal for marine and industrial applications.
Cupro Nickel products are extensively used in industries that operate in harsh aqueous environments. Key applications include marine and shipbuilding (piping, heat exchangers, hull sheathing), offshore oil & gas (subsea systems, firewater lines), desalination plants (evaporator tubes, brine heaters), and coastal power generation (condenser tubing). Their resistance to seawater corrosion and biofouling is critical in these sectors.
The primary difference lies in their nickel content: C70600 contains 10% nickel, while C71500 contains 30% nickel. While both offer excellent seawater corrosion resistance, C71500 (70/30) provides superior strength and enhanced resistance to erosion and impingement attack, particularly in higher velocity and more aggressive seawater conditions. C70600 (90/10) is often preferred for its better anti-fouling characteristics and slightly higher thermal conductivity.
At Dipti Metal Industries, we supply Copper Nickel C70600 and C71500 alloys in a wide array of product forms. This includes pipes and tubes (seamless and welded), pipe fittings (butt-weld, socket weld, threaded), flanges of various types, bars (round, square, flat, hexagonal), and sheets and plates to meet diverse project and fabrication needs.
Absolutely. As a leading manufacturer and exporter, we guarantee full traceability for all our products. Every shipment of Copper Nickel Alloy Products includes the mandatory EN 10204 3.1 Mill Test Certificate (MTC). This certificate provides comprehensive details on the precise chemical analysis, mechanical test results, and all relevant inspection data of the specific heat batch used for your materials, ensuring full compliance with international standards and project specifications.
