ASTM B111 C70600 Copper Nickel 90/10 Seamless Tube is a type of tube material that is made from a copper-nickel alloy. This particular alloy consists of approximately 90% copper and 10% nickel, hence the designation "90/10." The ASTM B111 specification establishes the requirements for this type of seamless tube, which is commonly used in heat exchangers, condensers, and similar applications in marine environments where corrosion resistance is critical.
The addition of nickel to the copper improves the strength and corrosion resistance of the material, making it particularly suitable for use in saltwater environments. The 90/10 copper-nickel alloy is known for its durability, thermal stability, and excellent resistance to biofouling in seawater.
