As the leading supplier of copper nickel, Farmers Copper Ltd. is your source for copper nickel C71500 (70/30), available in sheet, plate, rod, pipe, tube, fittings and flanges. This copper nickel alloy is known for its moderate strength, workability, formability and weldability. C715 copper alloy is also known as 70/30 copper nickel, as it is comprised of 30% nickel. 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 C715 alloy an extraordinary resistance to general corrosion and stress corrosion cracking, making it very suitable and ideal for the marine or industrial industries.
