Why choose ABRATIG NiCu7 filler metal?

Choosing ABRATIG NiCu7 (a nickel-copper based alloy) offers several advantages, particularly in terms of resistance to corrosion, cracking and certain marine or chemical conditions.

  1. Excellent corrosion resistance

NiCu7 performs well in :

  • marine environments (seawater, salty atmosphere),
  • weak acid or alkaline environments,
  • chlorinated or sulfur-containing solutions.

This makes it a preferred choice for the naval, chemical and petrochemical industries.

  1. Excellent toughness and ductility

Even at low temperatures, NiCu7 retains good toughness, making it reliable for structures subjected to thermal or mechanical shock.

  1. Very good resistance to hot cracking

Thanks to its balanced composition of nickel and copper, ABRATIG NiCu7 is not susceptible to thermal cracking during welding – a real plus for repairs or delicate assemblies.

  1. Good thermal and electrical conductivity

Copper provides good conductivity, useful in certain technical applications or for welding conductive materials.
