Description of material
EG1 is a single phase solid solution Nickel – Copper alloy with very high corrosion resistance in marine and chemical environments and excellent mechanical properties at sub-zero temperatures, as well as good high temperature properties up to 450 C°. The yield and tensile strength of this grade can only be increased by cold working. Depending on the chemical balance of each heat, EG1 could have a ferromagnetic behavior and this should be evaluated if magnetic permeability were a concern.
Applications
Many marine applications such as fasteners, pumps and some kinds of propeller shafts, valves, tanks and any device or marine fixture for sea water service. Mostly used in off shore structures, in desalination and chemical plants and in sour gas environments.
