  • Procedure for forming small wires
    Patent number: 3943619
    Abstract: A procedure for drawing ultrafine wires is disclosed which incorporates the steps of inserting a core wire of a selected material into a plurality of telescoped sacrificial sheaths, welding the ends of the core wire to the sheath and successively drawing the combination down to a predetermined diameter. The outside sheath is sacrificed by etching to free the proportionately reduced core wire. The core wire may be initially covered with Teflon to aid in the reduction and the Teflon is removed by exposure to heat.
