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. The alloy if often referred to as Copper Nickel 70/30 because it is made up of 30% nickel in it's composition. The standard designation for c715 Copper Nickel is ASTM B466 and ASME SB466. 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.
