Monel 404 alloy is a single-phase solid solution Ni-Cu alloy, which has good corrosion resistance in many media environments. From a slight oxidizing medium environment to a neutral environment, to a suitable reducing environment, it has good corrosion resistance. This alloy has a long history of use as a corrosion-resistant material.
