Abstract
A die for drawing wire of a predetermined diameter comprising an optically non-opaque CVD diamond body having a thermal conductivity greater than 4 watts/cm-K with an opening extending through said body and having a wire bearing portion of substantially circular cross-section determinative of the diameter of the wire.
Claims5
A die for drawing wire comprises
- (1) a substantially transparent polycrystalline CVD diamond body having a thermal conductivity greater than 4 watts/cm-k and a uniform small diamond grain structure of less than about 5 microns throughout its cross section and an opening for receiving wire fed through said opening during drawing, and
- (2) a support body for supporting the diamond body, whereby the wear resistance of said die is substantially improved.
