The Copper Nickel 70/30 Coils are composed of 70% copper and 30% nickel, with trace additions of iron and manganese to improve strength and corrosion resistance. This balanced chemical composition gives the alloy its excellent performance characteristics. The material conforms to ASTM B122 / ASME SB122 Grade UNS C71500, a globally recognized specification for copper-nickel alloys used in marine and industrial engineering applications. These coils are widely preferred for their resistance to biofouling, stress corrosion, and impingement attacks, especially in seawater environments.

In different parts of the world, these coils are known by various standard equivalents. In the United States, they are designated as ASTM B122 UNS C71500, while in European standards, they are referred to as EN CW354H. In the UK, they are classified under BS 2871 CN107, and in Japan, the equivalent standard is JIS C7150. The German standard lists this material as DIN 2.0882, ensuring international recognition and interchangeability across different markets.
