What is the difference between YT-type cemented carbide and YG-type cemented carbide

1. Different ingredients

The main components of YT-type cemented carbide 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.

The main components of YG cemented carbide are tungsten carbide (WC) and cobalt (Co) as a binder. 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.
2. Different performance

YT-type cemented carbide has good wear resistance, decreased bending strength, grinding performance, and thermal conductivity, while YG-type cemented carbide has good toughness, good grinding performance, and good thermal conductivity, but its wear resistance is higher than that of YT-type cemented carbide. much worse

3. Different scope of use

YT-type cemented carbide is suitable for high-speed cutting of general steel due to its high low temperature brittleness, while YG-type cemented carbide is used for processing brittle materials (such as cast iron) non-ferrous metals and alloy steels.
