Resistant to: Atmospheric corrosion: formation of the a greenish protective patina due to the formation of copper basic salts (such sulphates, chlorides in marine environment, nitrates and carbonates). Cu-DHP has a good resistance in natural and industrial atmosphere. Industrial and drinking water, aqueous and alkaline solutions (not oxidizing), pure water vapor (steam), non oxidizing acids (without oxygen in solution) and salts, neutral saline solutions. Practically resistant against stress corrosion cracking .
