ASTM B230/B230M-07 (R2021) pdf free download.Standard Specification for Aluminum 1350-H19 Wire for Electrical Purposes.
1.1 This specification covers aluminum 1350—H19 (extra hard) round wire for electrical purposes.
1.2 The values stated in inch-pound or SI units are to he regarded separately as standard. The values in each system are not exact equivalents: therefore, each system shall he used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.2. 1 For density. resistivity, and temperature, the values stated in SI units are to be regarded as standard.
Note 1—Prior to 1975 aluminum 1350 was designated EC aluminum.
Note 2—The aluminum and temper designations conform to ANSI F135.1/H35.IM. Aluminum 1350 corresponds to UNS A91350 in accordance with Practice E527.
Note 3—For definitions of terms found in this specification relating to uninsulated electrical conductors see Terminology B354.
5. Materials and Manufacture
5.1 The aluminum wire shall be made from drawing stock meeting the requirements of Specification B233.
6. Workmanship, Finish, and Appearance
6.1 The wire shall he free of imperfections not consistent with good commercial practice.
7. Tensile Properties
7. 1 Tensile Strength and Elongation—The wire shall conform to the tensile strength and elongation requirements set forth in Table I or Table 2 (Explanatory Note 3).
7.2 When requested by the purchaser, tension tests shall be made of specimens of wire containing joints made in the drawing stock or in the wire prior to final drawing. Such tests shall indicate tensile strengths not less than 90 % of the values for individual tests shown in Table I or Table 2.
7.3 When requested by the purchaser, tension tests of specimens containing joints in the finished wire, or in the final drawing, if permitted, shall he made. Such tests shall indicate tensile strengths to be not less than 11.0 ksi 1145 MPaI for electric-butt welded joints, and not less than 21 .0 ksi 175 MPaI for cold-pressure welded joints and electric-butt, cold-upset welded joints.
8. Bending Properties
8.1 The wire shall be free of brittleness as evidenced by its ability to be coiled or looped around its own diameter with or without a mandrel. No fracture shall occur. Slight surface checks shall not constitute cause for rejection.
9. Resistivity
9.1 The electrical resistivity shall not exceed the values shown in Table 3 (Explanatory Note 4).
10. Density
10. 1 For the purpose of calculating linear density. cross section. and so forth, the density of aluminum 1350 shall be taken as 2705 kg/mW3 [0.0975 lb/in3] at 20 °C [68 °F].ASTM B230/B230M pdf download.
