一般按合金成份進行分類，用途表述則對比渙散。 分類碳化鎢基硬質(zhì)合金：包含 WC—Co、WC—TaC—Co、WC—TiC—Co、 WC—TiC—TaC—Co、WC—Ti—TaC—NbC—Co 等合金，這些合金均以碳化鎢為主 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.

碳化鈦基或碳氮化鈦基硬質(zhì)合金：一般以 TiC 或 Ti（C、N）為根底成份， 以 Ni—Mo 作粘結(jié)劑而構(gòu)成的一種硬質(zhì)合金。這類硬質(zhì)合金近幾年又有很多新的 發(fā)展， 如含 Ta、 等重金屬元素的多元復式碳化物固溶體參加研發(fā)高性能 Ti W （C、 N）基金屬陶瓷等。

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.

碳化鉻基硬質(zhì)合金：以 Cr3C2 為基，以 Ni 或 Ni—W 等作粘結(jié)劑而構(gòu)成的硬 質(zhì)合金，一般用來作耐磨耐腐蝕零件，近幾年還很多用于裝飾品部件如表鏈等。

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.

鋼結(jié)硬質(zhì)合金：以 TiC 或 WC 為基，鋼作粘結(jié)劑而構(gòu)成的一種硬質(zhì)合金， 是一種可進行機加工和熱處理的合金， 是介于傳統(tǒng)硬質(zhì)合金與合金鋼之間的一種 工程資料。

涂層硬質(zhì)合金：一般指在韌性的碳化鎢基硬質(zhì)合金基體上經(jīng)過化學氣相 堆積或物理涂層辦法，涂上幾微米厚的 TiC、TiN、Ti（C、N）、Al2O3 之類的硬 質(zhì)化合物而出產(chǎn)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.
