Copper Nickel 706 / C706 / C70600
Farmer’s Copper Ltd. maintains an extensive inventory of Copper Nickel C706 in bar, plate, sheet, tube, pipe, fittings, and flanges. C706 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron also give the alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities.
Typical Applications
- Desalination
- Underwater tubing
- Exchangers
- Marine hardware
Farmer’s Copper Ltd. established in 1920, is committed to achieving the goals set by our customers. Contact our knowledgeable sales associates today to inquire as to how we can assist you in your copper nickel needs!
