Incoloy®Alloy 825

Incoloy®Alloy 825 (Nickel-Iron-Chromium alloy) with addition of copper and molybdenum .Against aqueous corrosion it has better resistance as compared to Incoloy 800, otherwise both are same .To provide exceptional resistance against many corrosive environments is how the chemical composition of Incoloy®Alloy 825 is designed .Incoloy®Alloy 825 is specially resistant to sulfuric and phosphoric acids.
