Claims20
A method for producing an aluminum wire from an aluminum rod, the method comprising:
- cold-drawing the aluminum rod at a temperature in a range from about 40° F. to about 250° F. to reduce the cross-sectional area, producing the aluminum wire;
- wherein the aluminum rod is a cylindrical rod having a diameter in a range from about 0.2″ to 0.35″,
- the ratio of the cross-sectional area of the aluminum rod to the aluminum wire is in a range from about 3:1 to about 10:1,
- the aluminum wire has a tensile strength in a range from about 17,000 to about 22,000 psi, and
- the aluminum wire is not annealed.
