Synthetic diamond industry and the industry chain analysis

⑴, many types of hard materials
Hard materials include cemented carbide (tungsten carbide powder, tantalum carbide, vanadium carbide,Diamond blade and other hard powder), ceramic materials (silicon nitride, aluminum oxide) and the superhard material (diamond, PcD, CBN (cubic nitride boron)), and other. High-speed tool steel, tungsten, molybdenum, chromium, vanadium, cobalt and sometimes as the main alloying elements carbon high alloy ledeburite, commonly used as high-speed cutting tools.
Tungsten carbide based cemented carbide: Tungsten carbide (WC) based alloy mainly composed of WC, mainly divided tungsten-cobalt (WC-Co) Class Carbide (YG class), tungsten, titanium cobalt (WC-TiC-Co) class carbide (YT class), tantalum, tungsten, titanium (niobium) cobalt (WC-CT aC (NbC)-Co) class Carbide (YW) and other three categories.
Titanium carbide-based synthetic diamond carbide or titanium based carbonitride: usually TiC or Ti (C, N)-based ingredients, and Ni-Mo as a binder composed of a cemented carbide. In recent years, there are many such abrasive grinding developments, such as those containing Ta, W and other heavy elements in solid solution carbide multi penthouse join developing high-performance Ti (C, N) cermet and so on.
Chromium carbide based cemented carbide: the Cr3C2-based, with Ni or Ni-W which consists of a binder such as carbide, usually used as a corrosion resistant parts, in recent years, but also a large number of components used in decorations such as bracelets and so on.
