Compatible Materials
Single-crystal diamond drawing dies are ultra-precision wire drawing tools constructed with a highly polished natural or synthetic diamond core mounted in a metal (usually stainless steel) casing. They are used to draw wire down to extremely fine diameters with exceptional accuracy and surface quality. Thanks to diamond’s unrivaled hardness and strength, these dies deliver superior wear resistance, outstanding dimensional accuracy, and the best surface finish of any die material. Wire drawn through a single-crystal diamond die achieves virtually flawless smoothness and consistent roundness, even at micrometer sizes.
