Tensile Properties7.1 The wire of a
28、 designated alloy shall be drawn toconform to the tensile requirements prescribed in Table 1 (seeExplanatory Note 3 and Explanatory Note 4).7.2 Tests on a specimen containing a joint shall show atleast 95 % of the minimum tensile strength given in Table 1.Elongation tests shall not be made on a spec
29、imen containing ajoint.7.3 Nominal wire diameters between those listed in Table 1,shall conform to the requirements of the next larger size if (1)the nominal diameter is greater than 0.003 in. (3 mils) (0.076mm) larger than a listed size whose diameter is 0.100 in. (2.5mm) or greater, or (2) the nom
30、inal diameter is greater than0.002 in. (2 mils) (0.051 mm) larger than a listed size whosediameter is less than 0.100 in. (2.5 mm) diameter.7.4 Tension tests shall be made on representative samples.The elongation of the wire shall be determined by measuringthe permanent increase in length, due to th
31、e breaking of thewire in tension, between gauge marks placed originally 10 in.(250 mm) apart upon the test specimen (see Explanatory Note5).7.5 If any part of the fracture takes place outside the gagemarks or in the jaws of the testing machine, or if an examina-tion of the specimen indicates a flaw,
32、 the value obtained maynot be representative of the material. In such cases the test maybe discarded and a new test made.7.6 RetestsIf upon testing a sample from any coil orspool of wire, the results do not conform to the requirementsprescribed in Table 1, two additional samples shall be tested,and
33、the average of the three tests shall determine the accep-tance or rejection of the coil or spool.8. Resistivity8.1 Electrical resistivity shall be determined on representa-tive samples by resistance measurements (see ExplanatoryNote 6). At a temperature of 20C the resistivity shall notexceed the val
34、ues shown in Table 3 for the designated alloy.8.2 The electrical resistivity of the material shall be deter-mined in accordance with Test Method B193.9. Diameter and Permissible Variations9.1 The wire sizes shall be expressed as the diameter of thewire in decimal fractions of an inch or a millimetre
35、 to thenearest 0.0001 in. (0.001 mm) (see Explanatory Note 3).9.2 The wire shall not vary from the specified diameter bymore than the amounts shown in Table 4.9.3 Ten percent, but not less than five coils or spools (or allif the lot is less than five) from any lot of wire shall be gagedat three plac
36、es. If accessible, one gaging shall be taken neareach end and one near the middle. If any of the selected coilsor spools fails to conform to the requirements prescribed in 9.2,all coils or spools shall be gaged in the manner specified.10. Density10.1 For the purpose of calculating mass per unit leng
37、th,cross sections, etc., the density of the various alloys shall betaken as shown in Table 5, based on a temperature of 20C.11. Joints11.1 No joints shall be made in the completed wire (seeExplanatory Note 7). Joints in wire and rods, prior to finaldrawing, shall be made in accordance with the best
38、commercialpractice and shall conform to the requirements prescribed in7.2.12. Finish12.1 The wire shall be free from all imperfections notconsistent with the best commercial practice.13. Inspection13.1 All tests and inspection shall be made at the place ofmanufacture unless otherwise especially agre
39、ed upon betweenthe manufacturer and the purchaser at the time of purchase. Themanufacturer shall afford the inspector representing the pur-chaser all reasonable facilities to satisfy him that the materialis being furnished in accordance with this specification.TABLE 2 Chemical RequirementsElement Co

44、eE527) is a simple expansion of the former standard designation systemaccomplished by the addition of a prefix “C” and a suffix “00.” The suffixcan be used to accommodate composition variations of the base alloy.NOTE 2It is the intention of this specification to permit under each ofthe alloys listed
45、 in 1.2 any alloy coming within the total range of analysisspecified in Section 5, provided the product conforms to the otherrequirements of this specification. For purposes of information only, thetypes of alloy now commonly used for each of the several alloys are listedbelow. Certain alloys that h
46、ave a “commercial standing” may have beenassigned a UNS designation (see 1.2). The chemical composition of any ofthe materials shall be within the total range specified in Section 5, but inno case shall the alloy contain the allowed maximum of more than oneconstitutent other than copper.Alloy Alloy
