Wire tensile strength is the pull required to break the wire, measured in PSI. High-quality stitching wire has a tensile range of 135,000–165,000 PSI. Tensile above 165,000 PSI causes premature wear on stitching heads and trimmer knives, increasing maintenance costs. Tensile below 135,000 PSI results in soft wire that may not form proper stitches. High-tensile wires offer cost benefits for thicker applications but are outweighed by wear on equipment.
