QuCu87 Rod – Laser Welding Wire Copper-Nickel CuNi30 / 2.0837 (ERCuNi) – Offshore, Sea Water

QuCu87 Rod – Laser Welding Wire Copper-Nickel CuNi30 / 2.0837 (ERCuNi) – Offshore, Sea Water

QuCu87 is the copper-nickel wire: EN ISO 24373 S/G Cu 7158 (CuNi30) · AWS A5.7 ERCuNi · material no. 2.0837. With 30 % nickel it matches CuNi30Fe (2.0882) and CuNi20Fe (2.0878).

CuNi alloys are the standard material for sea-water piping — in offshore engineering, shipbuilding and desalination plants. The wire is sea-water resistant and highly corrosion resistant, designed for heavily loaded joint welds, not just build-ups.

Recommended base materials

  • CuNi30Fe (2.0882)
  • CuNi20Fe (2.0878)
  • Copper-nickel alloys with up to 30 % nickel

Typical applications

  • Offshore engineering
  • Desalination plants
  • Shipbuilding — sea-water piping
  • Chemical plant construction

Properties and advantages

  • Sea-water and highly corrosion resistant
  • For heavily loaded joint welds
  • 115 HB, Rp0.2 210 MPa · Rm 380 MPa · A 30 %
  • Titanium-stabilised (Ti 0.50 %) — suppresses porosity

Rod form advantage: Constant wire feed when repairing sea-water piping.

Rod form: Rod lengths 1000 mm and 333 mm, Ø 0,2 mm – 0,8 mm.
