Application field UTP A 80 M is suitable for joining and surfacing of nickel-copper alloys and of nickel-copper-clad steels. Particularly suited for the following materials: 2.4360 NiCu30Fe, 2.4375 NiCu30Al. UTP A 80 M is also used for joining different materials, such as steel to copper and copper alloys, steel to nickel-copper alloys.These materials are employed in high-grade apparatus construction, primarily for the chemical and petrochemical industries.A special application field is the fabrication of seawater evaporation plants and marine equipment. Welding properties The weld metal has an excellent resistance to a large amount of corrosive medias, from pure water to nonoxidising mineral acids, alkali and salt solutions.
