Copper Nickel 70 30 also known as CuNi 70 30 or Cupro Nickel 70 30 developed to work in offshore and Marine Applications

Siddhagiri Metals and Tubes has been supplying Copper Nickel Alloy for more than 25 years and has developed the resources, skills and inventory to satisfy the critical needs of our client's across the globe. We specialise in Copper-Nickel Alloys, Nickel Alloys and Stainless Steel products that have applications across a multitude of markets and industries. Copper-nickel alloys were developed specifically for seawater service. Cupro Nickel Alloys are currently used in sizeable quantities for Offshore, Power, Desalination, Marine, Chemical Processing, Petrochemical & Refining and Oil & Gas industries. 70/30 is best renowned for its excellent corrosion and erosion resistance, especially in marine environments. The corrosion resistance of 70 30 CuNi is improved to 4.5m/s in higher velocity waters and polluted seawater. CuNi 70 30 is composed of 30% Nickel, 0.7% Iron, 1.0% Manganese and remainder as Copper. The most popular specifications covering this 70 30 Copper-Nickel are UNS C71520, UNS C71500, DIN 2.9882, SAE J461, SAE J463, CW354H, BS 2874, EN 12164, dgs320, CuNi30Mn1fe.
