Key Features of 70/30

  • Excellent corrosion and pitting resistance in marine environments
  • Good strength and toughness
  • Resistance to biofouling
  • Readily weldable and fabricated

1.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

Copper nickel 70 30 thermal conductivity is 29 W/(m·K). The Elongation at Break of Copper nickel (rolled-H04 for flat products/hard drawn-H80 for tubing), is 11.00% and its Elongation at Break (annealed), is 40%. The Density of 70/30 Copper nickel is 0.323 lb/in³ (8.94 g/cm3). Cupro Nickel 70/30 contains 70% copper and 30% nickel. It also has a small amount of manganese and iron in it, making it more resistant to erosion and corrosion. The resistance of 70/30 CuNi has been found to be much better in polluted seawater and in high-velocity waters (up to 4.5m/s). Related Specifications of 70/30 are C71500, DEF STAN 02-879 Annex B, BS2874, CuNi30Mn1Fe, CN107, NES780, DGS320, C71520, EN 12164, CW354H, ASTM B151, DEF STAN 02-780 and 2.0882.

Cu-Ni 70/30 has a Poisson’s Ratio of 0.325. The most popular specifications of 70/30 are the C71500 and CN107 designations. 70/30 Copper nickel is used in salt water piping and pipe fittings, refrigerator and condenser components, weld wire and boiler parts, salt water flanges, heat exchanger and cooling plants, welding backing rings, etc. Copper nickel 70/30 price can be easily determined by going online and searching for the same. Copper nickel has a Tensile Strength of 359 MPa (52000 psi). The Shear Modulus of Copper nickel is 57.2 GPa (8300 ksi). CuNi is the Molecular Formula of Copper nickel. Copper Nickel 70/30 can be readily welded, fabricated and cold worked, without the use of any special materials.
