1. A method for processing a thin strip material of high strength, low ductility metal, comprising the step of:

  • advancing a carrier metal strip between pressure rolls under tension;

    securing one end of a top lid metal strip to the carrier strip to be advanced between the pressure rolls with the carrier strip;

    inserting a single thin strip material of high-strength, low-ductility metal having a selected length and width and relatively smaller thickness between the top lid strip and the carrier strip to be carried between the pressure rolls with the strips;

    squeezing the top lid and carrier strips between the pressure rolls at room temperature by passing the strips between the rolls while maintaining the carrier metal strip under tension, thereby reducing the thickness of the thin strip material progressively along its length, and separating the material from the strips.
