High-performance ceramic materials have the characteristics of high hardness, good wear resistance, strong chemical stability, excellent high-temperature mechanical properties and not easy to bond with metals, and can be widely used in the processing of difficult-to-process materials.
    In the past thirty years, due to the effective control of raw material purity and grain size in the ceramic material manufacturing process, various carbides, nitrides, borides, oxides, whiskers or a small amount of metal addition technology have been developed. And the use of various toughening and strengthening mechanisms has greatly improved the strength, toughness and impact resistance of ceramic materials.
    From the results of foreign research, ceramic material drawing dies have been widely used in the field of molds, and there have been many patents in Japan, the United States, France and other countries. Although ceramic wire drawing dies have not been widely used in China, with the continuous improvement of manufacturing technology, ceramics will be a good wire drawing die material suitable for the wire drawing industry.
