C11000 has incredible corrosion resistance to weathering and very good resistance to many chemical substances. It's miles often used specially for corrosion resistance. It's far appropriate to be used with maximum waters, and can be used underground as it resists soil corrosion. It resists non-oxidising mineral and natural acids, caustic solutions and saline answers. Relying on concentration and specific conditions of publicity, copper commonly resists: acids mineral acids which include hydrochloric and sulphuric acids; organic acids such as acetic acid (along with acetates and vinegar), carbolic, citric, formic, oxalic, tartaric and fatty acids; acidic answers containing sulphur, together with the sulphurous acid and sulphite answers utilized in pulp mills. Alkalies fused sodium and potassium hydroxide; concentrated and dilute caustic solutions. Salt answers aluminium chloride, aluminium sulphate, calcium chloride, copper sulphate, sodium carbonate, sodium nitrate, sodium sulphate, zinc sulphate. Waters all potable waters, many commercial and mine waters, seawater and brackish water. The corrosion resistance of c11000 isn't always adequate for: ammonia, amines and ammonium salts; oxidizing acids together with 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 together with sulphuric and acetic acids, even though it is almost immune from these acids if air is completely excluded. Copper is not appropriate for use with acetylene, which can react to form an acetylide that's explosive. C11000 is taken into consideration to be immune to pressure corrosion cracking in ammonia and the same media which reason season cracking in brass and other copper alloys.
The fatigue strength is described as the maximum bending strain amplitude which a fabric withstands for 107 load cycles below symmetrical exchange load without breaking. It's miles depending on the mood tested and is set 1/three of the tensile strength .
