CATEGORY

TYPE

Solid Nickel based filler metal alloyed with Copper.

APPLICATIONS

Shipbuilding, seawater evaporation plants, tubes, pump building, offshore etc. NiCu30Mn is suitable for dissimilar welding between Nickel 200-201, stainless steel, carbon steel, Inconel and Incoloy alloys, Nickel Copper and Copper nickel alloys.

PROPERTIES

This Nickel - Copper weld metal has properties similar to “Monel 400”. It has good strength and resists corrosion in many media, including sea water, salts and reducing acids. The weld metal is not age hardenable and when used to join Monel K-500 it has lower strength then the base metal.
