Why choose ABRAFIL CuNi30?

  • Excellent corrosion resistance in marine environments:
    ABRAFIL CuNi30 is particularly effective against corrosion caused by seawater, including in spray zones and total immersion. It is a benchmark material for welding on hulls, piping or heat exchangers in saline environments.

  • Good resistance to erosion and impact:
    In addition to corrosion, this alloy resists erosion caused by rapid liquid flow, making it an excellent choice for cooling and seawater circulation circuits, or pump and turbine parts.

  • Mechanical and thermal stability:
    ABRAFILCuNi30 retains its mechanical properties at high temperatures, enabling it to be used in offshore, naval or chemical installations subject to significant thermal variations.

  • Compatibility with copper-nickel alloys (CuNi70/30, CuNi90/10):
    Allows CuNi alloys to be joined or repaired without creating problematic metallurgical differences, ensuring excellent continuity between base metal and filler metal.

  • Naval, offshore and industrial applications:
    Widely used in shipbuilding, oil rigs, desalination plants and the chemical industry, wherever corrosion, wear and reliability are critical.
