Sulfurous Acid Good Increased corrosion at elevated temperatures and with oxidizers axtm oxygen airdichromates, permanganates and sulfates Liquid metal Mercury Poor Severe liquid metal embrittlement Miscellaneous Glue Excellent Low corrosion rates, no localized attack Linseed 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.
High zinc content alloys preferred. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional mass, diameter, thickness, width, shape, specified and stock lengths, straightness, edge contour, and radius of edges or cornersmechanical tensile, yield and bend strengths, elongation, Rockwell hardness, and embrittlementelectrical ast, and chemical composition requirements.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It is informational only and not an official part of aetm standard; the full text of the b1877 itself must be referred to for its use and application. Acidic waters containing oxidizers are highly corrosive.
Noble metal salt, plates on copper surface. Physical Properties 1 Actual value. Nominal Grain Size 0. Highly oxidizing under acidic conditions.
Forms non-protective copper sulfide.
Black Liquor, Sulfate Process. Corrosion increases at elevated temperatures and in presence of oxidizers such as chromates or hypochlorates. Resistant at cryogenic and room temperatures.
Corrosion rate increases at elevated temperatures or with traces of moisture. Affected by pollutants and other environmental factors. Low corrosion rates, no localized attack. Combining values from the two systems may result in nonconformance with the specification. Chemical Composition Element Cu 1,2,3 1 Oxygen and trace elements may vary depending on the process.
Corrosion affected by water chemistry mineral content, acidity system design and fabrication. Hydrogen sulfide causes rapid tarnishing. Corrosion affected by salt concentration, temperature, velocity, dissolved oxygen content and pollutants. Road Bed Expansion Plates. Forms explosive compound in presence of moisture. Careful consideration must be given to specific contaminants when selecting materials for this complex environment.
This specification establishes the requirements for copper conductor bars, rods, and shapes for both electrical bus and general applications. Scaling at elevated temperatures. Protective green basic copper chloride or carbonate patina.
Strong agitation and aeration increases corrosion. Link to Active This link will always route to the current Active version of the standard. Contaminants such as water, sulfides, acids and various organic compounds can increase corrosion significantly.
More corrosion resistant in dry gas. The values qstm in each system are not exact equivalents; therefore, b18 system shall be used independently of the other. Increased corrosion at elevated temperatures and with oxidizers including oxygen airdichromates, permanganates and sulfates. Mine Water Fair Acidic waters containing oxidizers are highly corrosive. Erosion-corrosion at moderate velocities. Mixed oxide and sulfide scale forms.

Chromic Aastm Poor Severe oxidizing environment. Atmosphere, Marine Excellent Protective green basic copper chloride or carbonate patina. Corrosion increases with trace of moisture. Historical Version s – view previous versions of standard.
May affect color or taste. Atmosphere, Rural Excellent Low corrosion rates, no localized attack Chlor. C, C, C, C Suitable for neutral or alkaline conditions. Not suitable for hot concentrated solutions. Reduced corrosion resistance due to soluble complex ion formation.
