Standard Specification for Aluminum 1350 Drawing Stock for Electrical Purposes

ABSTRACT
This specification covers aluminium 1350 drawing stock for electrical purposes. The stock shall conform to the chemical composition requirements. The stock shall be uniform in quality and temper and shall be suitable for drawing into wire. The tensile strength tests and requirements for the respective tempers of stock are presented in details. The stock shall be furnished in continuous-length coils without joints, unless otherwise agreed upon between the manufacturer and purchaser. The electrical resistivity tests shall be made on full-section samples of the stock.
SCOPE
1.1 This specification covers aluminum 1350 drawing stock 0.375 in. (9.52 mm) to 1.000 in. (25.40 mm) in diameter, in the tempers shown in Table 1, for drawing into wire for electrical conductors (Explanatory Note 1 and Note 2).  
1.2 The SI values of density and resistivity are to be regarded as the standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate.
Note 1: Prior to 1975, aluminum 1350 was designated as EC aluminum.
Note 2: The aluminum and temper designations conform to ANSI H35.1. Aluminum 1350 corresponds to unified numbering system A91350 in accordance with Practice E527.    
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
