C, C, C, C Nominal Grain Size 0. Chemical Composition Element Cu 1,2,3 1 Oxygen and trace elements may vary depending on the process. Mixed oxide and sulfide scale forms. Corrosion affected by water chemistry mineral content, acidity system design and fabrication. Sea Water Good Corrosion affected by salt concentration, temperature, dissolved oxygen content and pollutants.
Standard Classification of Coppers.
Refer to specific salt solution ratings. Forms non-protective copper sulfide. Careful consideration must be given to specific contaminants when selecting materials for this complex environment. Acidic waters containing oxidizers are highly corrosive. Corrosion rate increases at elevated temperatures. Mine Water Fair Acidic waters containing oxidizers are highly corrosive. Increased corrosion asttm elevated temperatures and with oxidizers including oxygen airdichromates, permanganates and sulfates.
Soap Solutions Excellent Corrosion affected by salt concentration, temperature, velocity, dissolved oxygen content and pollutants. Sulfurous Acid Good Increased corrosion at elevated temperatures and with oxidizers including oxygen airdichromates, permanganates and sulfates Liquid metal Mercury Poor Severe liquid metal embrittlement Miscellaneous Glue Excellent Low corrosion rates, no localized attack Astk Oil Good Low corrosion rates, no localized attack Rosin Excellent Low corrosion rates, no localized attack Sewage Excellent Corrosion affected by salt concentration, temperature, velocity, dissolved oxygen content and pollutants.
Optimum resistance at room temperature and above boiling point. Hydrogen sulfide causes rapid tarnishing. Annealing Hot Treatment Nitric Acid Poor Severe oxidizing environment. Black Liquor, Sulfate Process.
Corrosion rate increases at elevated temperatures or with traces of moisture. Affected by pollutants and other environmental factors. Copper and copper alloys containing copper oxide susceptible to attack.
Steam Excellent Resistant to pure steam. Historical Version s – view previous versions of standard.
Strong agitation and aeration increases corrosion. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Corrosion increases at elevated temperatures and in presence of oxidizers such as chromates or hypochlorates. Erosion-corrosion at moderate velocities. Physical Properties 1 Actual value.
– C Alloy
h187 Rapid corrosion increases with traces of moisture. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Water, Potable Excellent Corrosion affected by water chemistry mineral content, acidity system design and fabrication.
Pitting in hot water caused by cathodic deposits. Other coppers may be used upon agreement between supplier and purchaserer.
ETP Copper 110 / C110 / C11000
Resistant up to F unless contaminated by water, acids, alkalies or salts. Erosion-corrosion at high velocities. Chromic Acid Poor Severe oxidizing environment. Sodium Peroxide Fair Oxidizing environment Sulfur comp. Suitable for neutral or alkaline conditions.
This specification establishes the requirements for copper conductor bars, adtm, and shapes for both electrical bus and general applications. May affect color or taste.
Not suitable for hot concentrated solutions. Scaling at elevated temperatures. Forms explosive compound in presence of moisture. Carbon dixide, dissolved oxygen or ammonia can increase corrosion. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
Atmosphere, Marine Excellent Protective green basic copper chloride or carbonate patina. Free qstm dioxide can cause pitting in cold water. Coated With Lead Alloy.
Combining values from the two systems may result in nonconformance with the specification. Reduced corrosion resistance due to soluble complex ion formation.
