Copper Nickel Coils are an alloy combination of copper and nickel, typically comprising 90% copper and 10% nickel or 70% copper and 30% nickel, depending on the grade. These alloys are further strengthened with small additions of iron and manganese, improving corrosion resistance and overall performance. Manufactured according to ASTM B122 and ASME SB122 standards, these coils ensure global quality compliance. Known for their outstanding thermal conductivity, anti-fouling characteristics, and long service life, SMM Industries LLP has earned recognition as one of the most reliable Copper Nickel Coils Manufacturers serving international markets.

The Copper Nickel Coils are designed to withstand aggressive environments, including exposure to saltwater, acidic solutions, and fluctuating temperatures. The material’s inherent properties—such as resistance to stress corrosion, erosion, and biofouling—make it a preferred choice in industrial and marine systems. Available in popular grades such as CuNi 90/10 (UNS C70600) and CuNi 70/30 (UNS C71500), these coils are produced as per ASTM B122 / ASME SB122 specifications. Each product undergoes rigorous inspection for chemical composition, tensile strength, and dimensional accuracy, ensuring consistent quality and performance.

The key advantages of Copper Nickel Coils include outstanding corrosion resistance in marine and offshore environments, excellent resistance to hydrogen embrittlement, high thermal stability, and superior workability. Their non-magnetic nature and antimicrobial properties make them suitable for hygienic applications and fluid handling systems.

Additionally, their ability to retain mechanical strength at elevated temperatures makes them ideal for use in heat exchangers and condenser tubing. With these attributes, SMM Industries LLP stands as one of the leading Copper Nickel Coils Suppliers delivering performance-driven solutions to industries worldwide.
