Coating Carbide Cutting Tools---110×15.24×15.24
Carbide classification
① Tungsten and cobalt cemented carbide
The main components are tungsten carbide (WC) and binder cobalt
(Co).
Its grade is composed of "YG" ("hard and cobalt" in Chinese Pinyin)
and the percentage of average cobalt content.
For example, YG8 means the average WCo=8%, and the rest is
tungsten-cobalt carbide of tungsten carbide.
Generally, tungsten-cobalt alloys are mainly used in: cemented
carbide tools, molds and geological and mineral products.
② Tungsten-titanium-cobalt carbide
The main components are tungsten carbide, titanium carbide (TiC)
and cobalt. Its grade is composed of "YT" ("hard, titanium" two
characters in Chinese Pinyin prefix) and the average content of
titanium carbide.
For example, YT15 means that the average TiC=15%, and the rest is
tungsten-titanium-cobalt carbide with tungsten carbide and cobalt
content.
③ Tungsten-titanium-tantalum (niobium) cemented carbide
The main components are tungsten carbide, titanium carbide,
tantalum carbide (or niobium carbide) and cobalt. This kind of
cemented carbide is also called general cemented carbide or
universal cemented carbide.
Its grade is composed of "YW" (the Chinese phonetic prefix of
"hard" and "wan") plus a sequence number, such as YW1
