一般按合金成份进行分类，用途表述则对比涣散。 分类碳化钨基硬质合金：包含 WC—Co、WC—TaC—Co、WC—TiC—Co、 WC—TiC—TaC—Co、WC—Ti—TaC—NbC—Co 等合金，这些合金均以碳化钨为主 成份。

Generally, alloys are classified according to their composition, while their use is comparatively lax. Classified tungsten carbide-based cemented carbides: including WC-Co, WC-TaC-Co, WC-TiC-Co, WC-TiC-TaC-Co, WC-Ti-TaC-NbC-Co and other alloys, these alloys are mainly composed of tungsten carbide.

碳化钛基或碳氮化钛基硬质合金：一般以 TiC 或 Ti（C、N）为根底成份， 以 Ni—Mo 作粘结剂而构成的一种硬质合金。这类硬质合金近几年又有很多新的 发展， 如含 Ta、 等重金属元素的多元复式碳化物固溶体参加研发高性能 Ti W （C、 N）基金属陶瓷等。

TiC-based or Ti N-based cemented carbides: A cemented carbide consisting of TiC or Ti (C, N) as the base component and Ni-Mo as the binder. In recent years, there have been many new developments in this kind of cemented carbides, such as the multi-component compound carbide solid solution containing Ta and other heavy metal elements, participating in the research and development of high-performance Ti W (C, N) based cermets and so on.

碳化铬基硬质合金：以 Cr3C2 为基，以 Ni 或 Ni—W 等作粘结剂而构成的硬 质合金，一般用来作耐磨耐腐蚀零件，近几年还很多用于装饰品部件如表链等。

Chromium Carbide-based Cemented Carbide: A cemented carbide based on Cr3C2 and using Ni or Ni-W as binder. It is generally used as wear-resistant and corrosion-resistant parts. In recent years, it has been widely used in decorative parts such as watch chains.

钢结硬质合金：以 TiC 或 WC 为基，钢作粘结剂而构成的一种硬质合金， 是一种可进行机加工和热处理的合金， 是介于传统硬质合金与合金钢之间的一种 工程资料。

涂层硬质合金：一般指在韧性的碳化钨基硬质合金基体上经过化学气相 堆积或物理涂层办法，涂上几微米厚的 TiC、TiN、Ti（C、N）、Al2O3 之类的硬 质化合物而出产的。

Steel-bonded cemented carbide: A cemented carbide based on TiC or WC and steel as binder. It is a kind of alloy that can be machined and heat treated. It is a kind of engineering data between traditional cemented carbide and alloy steel.

Coated cemented carbide: Generally speaking, it is produced by chemical vapor deposition or physical coating on tough tungsten carbide matrix, coated with hard compounds such as TiC, TiN, Ti (C, N), Al2O3 and so on, which are several microns thick.
