The submicron and ultrafine cemented carbide currently put into commercial production mainly consists of submicron and ultrafine WC, Co powder and appropriate grain length.
It is prepared from large inhibitors (mainly Cr3C2, VC), and its grain size is 0.2~0.8μm.
Due to the unique properties of submicron and ultrafine cemented carbide, they are widely used in micro drilling and micro milling of printed circuit boards.
Performance solid carbide cutting tools; processing printed circuit boards, plastics and PTFE, carbon fiber and graphite materials, paper
Respectively steel, nickel-based alloys and aerospace titanium alloys, etc. Now it is expanding into the fields of high tensile strength, wood and resin laminated materials, reinforced glass fiber and resin-filled ceramics, cast iron, carbon steel, stainless steel and heat-resistant high-performance mold plates, drawing dies and other fields, and is expected to enter the field.
There are more application fields of traditional cemented carbide. Metallographic structure of typical grades of submicron and ultrafine cemented carbide
