Description

Copper-nickel rod 90/10
The weld metal of this wire is developed to match CuNi 90/10 alloys and is nominally composed of 86% Cu and 10.5% Ni. Applications include offshore constructions, desalination plants, evaporators, condensers, and seawater and brackish water treatment facilities.

Description

Application

This consumable is ideal for cladding and plating operations, provided that a buttering layer is applied. Usually, this buttering is executed with alloy 400 or pure nickel. It is widely used in offshore constructions, desalination plants, evaporators, condensers, and saltwater and marine treatment systems. Preheating is generally not necessary, with a maximum interpass temperature of 150 °C and no post-weld heat treatment (PWHT). It is crucial to avoid any contamination in the weld zone with foreign materials, particularly those from lead, tin, or zinc, to prevent cracks in the weld metal.

Alloy Type

90/10 copper-nickel alloys.

Microstructure

Solid solution, single phase alloy.
