Copper Nickel C715 - C71500 Standards

ASTM B151, ASTM B466, ASTM B111, ASTM B171, ASME SB466, ASME SB111, ASME SB151, ASME SB171, DIN 2.0872, BS 2871 CN102, EN CW352H, MIL-C-1726F, MIL-C-24679, MIL-T-16420K

Ratnashri metal 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 weld ability. The alloy if often referred to as Copper Nickel 70/30 because it is made up of 30% nickel in its 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.
