①The main components of tungsten cobalt cemented carbide are tungsten carbide (WC) and binder cobalt (CO). Its grade is composed of "YG" ("hard, cobalt" two words Chinese pinyin words) and the average cobalt content of the percentage. For example, YG8, which represents the average WCo=8%, the rest is tungsten carbide of tungsten cobalt carbide. General tungsten cobalt alloy is mainly practical in: cemented carbide tools, molds and mineral products.

②The main components of tungsten titanium cobalt cemented carbide are tungsten carbide, titanium carbide (TiC) and cobalt. Its grade is composed of "YT" ("Hard, titanium" two words Chinese pinyin words) and titanium carbide average content. For example, YT15, which represents the average TiC=15%, the rest is tungsten carbide and cobalt content of tungsten titanium cobalt cemented carbide.

③The main components of tungsten Titanium tantalum (niobium) cemented carbide are tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This type of cemented carbide is also known as General cemented carbide or universal cemented carbide. Cemented carbide can also be used to make rock drilling tools, extraction tools, drilling tools, measuring gauges, wear-resistant parts, metal abrasives, cylinder linings, insert bearing, spray nozzle, metal mould (Such as wire drawing die, bolt die, nut die, and all kinds of fastener dies The excellent properties of cemented carbide gradually replace the previous steel molds.)
