摘要： A method for producing wire with a small cross-sectional area and good mechanical properties is disclosed. The method comprises the steps of providing metallic coil stock of blackplate thickness with a specific microstructure and an essentially uniform cross-section, positioning in engaging relationship a pair of monolithic cutting rolls, feeding the stock into the nip formed by the rolls and then slitting the stock by shear fracture into wire with an aspect ratio of less than about 25. The method is characterized by an extended life of the cutting rolls.
