CuNi 70-30
Description
70/30 copper-nickel solid wire
The weld metal of this wire rod is designed to match the CuNi 70/30 alloys and is nominally 67% Cu and 30% Ni. The consumable is suitable for surfacing and cladding provided buffer layer is made (normally buttering is made with alloy 400 or pure nickel). Applications include offshore construction, desalination plant, evaporators, condenser, etc, in salt and sea water processing system.
