Copper Alloy 710 (C71000)
Copper-Nickel, 80/20

Alloy C710 copper tubing, commonly known as 80/20 Copper-Nickel, has excellent corrosion resistance, particularly in marine and industrial environments. This alloy is widely used in seawater piping systems, heat exchangers, and condensers due to its superior resistance to biofouling and stress corrosion cracking.
