Tungsten can be drilled, turned, milled, planed and ground. However, machining operations require experience and close adherence to optimum conditions. Preheating to about 200℃ and the use of cemented carbide tools are recommended. Complex shapes and holes can be formed by spark erosion; the tungsten workpiece forms the anode and the working electrode the cathode.
Tungsten (pure W, doped W, W-Re) is commercially available as wrought products (sintered bars, billets, forgings, rods, pins, disks, cylinders, tubes, sheet, strips, ribbons, wires) as well as in the form of a broad variety of shaped parts(crucibles, springs, heating elements, rivets, etc.).
Cold-rolled sheet is supplied in thicknesses from 0.025 to 0.4mm (up to 500mmxl000mm). Hot-rolled tungsten is available with thicknesses from 0.4 to 8.0mm (maximum lengths, 1500mm). Tungsten wires are manufactured from about I mm down to 5 µm.
