Product information

Copper-Nickel type welding rod for welding seawater resistant copper nickel alloys, e.g.types Cu Ni 10 and Cu Ni 30, known as Cunifer alloys, which are frequently used in seawater cooling systems. No flux is needed, but joint surfaces and adjacent areas must be thoroughly cleaned. Use pure argon as shielding gas for TIG welding.


  • High mechanical strength and toughness
  • High content of nickel


  • Less possibility for joint failure during operation
  • Large working area- can be used on Cunifer 10 and 30




Directions for use

DC - polarity when welding. The label on each container fully identifies the contents, and also gives basic information on application areas. Complete information on each flux label, and instructions for use are given in the handbook for maritime welders.
