Corrosion Resistance

C12200 has similar corrosion resistance to C11000. It gives excellent resistance to weathering and very good resistance to many chemicals. It is often used specifically for corrosion resistance. It is suitable for use with most waters, and can be used underground because it resists soil corrosion. It resists non-oxidising mineral and organic acids, caustic solutions and saline solutions.

Depending on concentration and specific conditions of exposure, copper generally resists:

Acids: mineral acids such as hydrochloric and sulphuric acids; organic acids such as acetic acid (including acetates and vinegar), carbolic, citric, formic, oxalic, tartaric and fatty acids; acidic solutions containing sulphur, such as the sulphurous acid and sulphite solutions used in pulp mills.

Alkalies: fused sodium and potassium hydroxide; concentrated and dilute caustic solutions.

Salt solutions: aluminium chloride, aluminium sulphate, calcium chloride, copper sulphate, sodium carbonate, sodium nitrate, sodium sulphate, zinc sulphate.

Waters: all potable waters, many industrial and mine waters, seawater and brackish water.

Other media: The corrosion resistance of C12200 is not adequate for: ammonia, amines and ammonium salts; oxidizing acids such as chromic and nitric acids and their salts; ferric chloride; persulphates and perchlorates; mercury and mercury salts. Copper may also corrode in aerated non oxidising acids such as sulphuric and acetic acids, although it is practically immune from these acids if air is completely excluded. Copper is not suitable for use with acetylene, which can react to form an acetylide which is explosive.
