Copper Nickel Pipe
Farmer’s Copper Ltd. maintains a broad inventory of Copper Nickel C70600 (90/10) and C71500 (70/30) in pipe form. Our inventory is composed of C706 in SCH. 40 & 80, along with Class 200, in addition to C715 in SCH 80. Copper Nickel is commonly used in seawater piping due to its complete resistance to barnacles and other marine organisms. Its resistance makes seawater fire fighting systems, desalination water systems, and similar applications much more reliable.
Typical Applications
- Marine hardware
- Desalination
- Seawater piping systems
- Cooling loops
- Pipe nipples
Farmer’s Copper Ltd. can cut material to fit your specifications on our bar saws, precisions, plate saws, shears, and water jets. Contact one of our experts today to find out how we can help meet your copper nickel needs.
