Copper Nickel C715 - C71500
Farmer’s Copper Ltd. continually maintains an inventory of C71500 (70/30) copper nickel in sheet, plate, rod, pipe, tube, fittings and flanges. C715 copper nickel is known for its moderate strength, workability, formability and weldability. Copper nickel alloy 715 finds its greatest application in areas of high temperatures and pressures combined with high velocity and destructive turbulence. The small iron content, up to 0.5%, gives the alloy an extraordinary resistance to general corrosion and stress corrosion cracking.
Typical Applications
- Condensers
- Seawater piping
- Power plants
- Exchanger shells
Farmer’s Copper Ltd. can offer you C71500 (70/30) copper nickel cut to your specifications through our precision plate saws, bar saws, shears and water jets.
