Material and Manufacture5.1 The rod shall be fabricated from copper of such qualityand purity that the finished product shall have the propertiesand char
16、acteristics prescribed in this specification.NOTE 1The following specifications define materials suitable for use:Classification B224, or Specification B5, or Specification B115,orSpecification B170.5.2 Copper of special qualities, forms, or types, as agreedupon between the manufacturer and the purc
17、haser and that willconform to the requirements prescribed in this specificationmay also be used.5.3 The rod coils shall be furnished in continuous lengthswith or without joints, as ordered.6. Chemical Composition6.1 Each rod type shall conform to the chemical composi-tion requirements prescribed in
18、Table 1 for the type of copperordered (Section 5).6.2 By agreement between the manufacturer and thepurchaser, the addition of silver up to an average of 30 troy ozper short ton of copper (0.10 %) will be considered within thespecification, copper including silver in the chemical analysis,with no ind
19、ividual silver analysis to exceed 35 troy oz per shortton (0.12 %). In the case of oxygen-free silver-bearing coppers,the designation OFS (oxygen-free, silver-bearing) will be usedas shown in Classification B224 and will include the UNS Nos.C10400, C10500, and C10700 as defined by the agreed silverc
20、ontent.6.3 Silver-bearing tough-pitch copper corresponds to thedesignation STP (silver-bearing tough-pitch) as shown inClassification B224 and to coppers having UNS Nos. C11300,C11400, C11500, and C11600.6.4 Oxygen ContentOxygen-free copper as describedherein is defined as a copper containing not in
21、 excess of0.0010 % (10 ppm) oxygen and produced without the use ofmetallic or other deoxidizers.7. Physical Property Requirements7.1 Electrical ResistivityResistivity of the copper in theannealed condition (See Note X1.1 and Table 2) shall notexceed the following values at 20C:Type of CopperResistiv
