Wire Dies - Free Standing Polycrystalline Diamond

DiaPac™ Free standing wire die blanks consist of diamond particles grown together under high pressure/high temperature with the help of a cobalt catalyst. This product offers high strength, uniform hardness and multi-directional wear resistance. These metal filled MF blanks are thermally stable up to 700 degrees celsius.

The cobalt can also be chemically removed from the blanks leaving a thermally stable TS diamond structure that can withstand temperatures up to 1200 degrees C. This is critical in drawing high temperature wire such as tungsten or for high temperature brazing of the blank into a steel casing.
