What are the cemented carbides?
General tungsten cobalt alloy is mainly applicable to: carbide cutting tools, molds and mineral products. Carbide cutting toolTungsten, titanium and cobalt carbideThe main components are tungsten carbide, titanium carbide (TiC) and cobalt. The grade by "YT" ("hard ti" Pinyin prefix) and the average content of titanium carbide.
For example, YT15, which represents average TiC=15%, is tungsten carbide cobalt carbide with the remainder of tungsten carbide and cobalt content.Tungsten, titanium, tantalum (niobium) carbidesTIC cutterIs the main component of tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide) and cobalt. This kind of hard alloy is also called universal cemented carbide or universal hard alloy.The grade by "YW" ("hard", "million" Pinyin prefix) and sequence number, such as YW1.
Tungsten cobalt carbideWC cutterThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.
