ASTM B111 Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes and Ferrule Stock.
ASTM B111 C71500 70-30 Copper-Nickel Seamless Tubes up to 3 1 ⁄ 8 in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.
Corrosion Resistance of ASTM B111 UNS C71500 Copper Coil for Heat Exchangers
Alloy Protection: The addition of nickel significantly enhances copper's corrosion resistance, particularly in seawater, chloride solutions, and high-temperature acidic environments. A dense oxide film (such as Cu₂O and NiO) forms on the alloy surface, effectively preventing the penetration of corrosive media.
Resistance to Pitting and Crevice Corrosion: Compared to other copper alloys, C71500 offers enhanced resistance to pitting and crevice corrosion, making it suitable for equipment exposed to long-term saltwater or sulfide-containing environments, such as ship components, desalination plants, and offshore platform piping.
Application Examples of ASTM B111 UNS C71500 Copper Tube for Buildings:
In marine engineering, C71500 is used in seawater coolers, brine piping, and ship propellers, ensuring long-term stable operation in harsh salt spray environments.
The chemical industry uses this alloy in distillers, heat exchangers, and catalyst supports, offering corrosion resistance in acidic or alkaline solutions.
