Common cemented carbide processing materials

The common cemented carbides can be divided into three types according to their composition and properties:tungsten cobalt,tungsten titanium cobalt and tungsten titanium tantalum(niobium).Tungsten cobalt and tungsten titanium cobalt cemented carbide are widely used in production.

(1)Tungsten cobalt cemented carbide

The main components are tungsten carbide(WC)and cobalt.The brand is represented by YG(Chinese phonetic alphabet for hard and cobalt),followed by the percentage value of cobalt content.For example,YG6 indicates that tungsten cobalt cemented carbide with 6%cobalt content has 94%tungsten carbide content.

(2)Tungsten titanium cobalt cemented carbide

The main components are tungsten carbide(WC),titanium carbide(TIC)and cobalt.The brand name is YT(Chinese phonetic alphabet for hard and titanium),followed by the percentage value of titanium carbide content.For example,YT15 represents tungsten titanium cobalt cemented carbide with 15%titanium carbide content.

(3)Tungsten titanium tantalum(niobium)cemented carbide

This kind of cemented carbide,also known as general cemented carbide or cemented carbide,is mainly composed of tungsten carbide(WC),titanium carbide(TIC),tantalum carbide(TAC)or niobium carbide(NBC)and cobalt.The brand name is indicated by the code YW(hard and WAN)followed by ordinal number.
