Electric wire or cable

Abstract

There is provided an aluminum-alloy material having sufficient electric conductivity and tensile strength as a wiring material and excellent in wire-drawing property, and an electric wire or cable using the same. An electric wire or cable includes an aluminum-alloy strand formed of an aluminum-alloy including Fe: 0.1% by mass or more to less than 1.0% by mass, Zr: 0 to 0.08% by mass, Si: 0.02 to 2.8% by mass, at least one of Cu: 0.05 to 0.63% by mass and Mg: 0.04 to 0.45% by mass, and the remainder being aluminum and unavoidable impurities.

The invention claimed is: 
     
       1. A method for producing an aluminum-alloy strand from an aluminum-alloy comprising:
 Fe: 0.1% by mass or more to less than 1.0% by mass  0.4 to 0.8% by mass; 
 Zr: 0 0.02 to 0.08% by mass; 
 Si: 0.02 to 2.8% by mass; 
 at least one of Cu: 0.05 to 0.63% by mass and Mg: 0.04 to 0.45% by mass; and 
 the remainder being aluminum and unavoidable impurities, 
 the method comprising the steps of: 
 (1) forming a wire rod using the aluminum-alloy; 
 (2) wire-drawing the wire rod, without a thermal treatment before the wire-drawing or in midstream of the wire-drawing, until becoming a desired final wire diameter; and 
 (3) continuously annealing or batch-wise annealing the wire-drawn wire rod which has been wire-drawn to produce the aluminum-alloy strand. 
 
     
     
       2. The method of claim 1, wherein the desired final wire diameter is 0.07 mm to 1.5 mm. 
     
     
       3. The method of claim 1, wherein the desired final wire diameter is 0.14 mm to 0.5 mm. 
     
     
       4. The method of claim 1, wherein the unavoidable impurities are 0.07% or less by mass. 
     
     
       5. The method of claim 1, wherein the unavoidable impurities are 0.05% or less by mass. 
     
     
       6. The method of claim 1, wherein the wire-drawing is performed using a dry wire-drawing machine. 
     
     
       7. The method of claim 1, wherein the wire-drawing is performed using a wet wire-drawing machine. 
     
     
       8. The method of claim 1, wherein the forming is performed by a continuous casting and rolling method. 
     
     
       9. The method of claim 8, wherein the rolling of the continuous casting and rolling method is hot rolling. 
     
     
       10. The method of claim 8, wherein the rolling of the continuous casting and rolling method is cold rolling. 
     
     
       11. The method of claim 1, wherein the forming is performed by an extrusion method.
