Aluminum Rod & Bar | The Aluminum Association
Aluminum rod, bar and wire products can be produced in several ways. One method is similar to rolling sheet. A long, square ingot is heated, progressively reduced in cross-section by passing it through a series of rolls, and then coiled. The coils are heated and, if slated to become wire, pulled through smaller and smaller dies.
