Cemented carbide die tools, which cemented carbide grade is the most wear-resistant

       

The smaller the particles of tungsten carbide, the higher the hardness and the more wear-resistant it is.

 

It mainly depends on the conditions of use. The most wear-resistant cemented carbide materials may be more brittle, so they may not be usable.

 

Cemented carbide is divided into multiple models according to hardness and toughness, such as yg8, yg15, etc. The wrong model has a great impact on the service life. Your household may be high-speed carbide (peak carbide) that contains a little tungsten but not tungsten carbide.

 

Non-standard wear parts

 

Cemented carbide is sintered with cobalt or other bonding metals using powder metallurgy technology with tungsten carbide as the main body, and its tungsten content is generally more than 80%.

 

Tungsten carbide is a kind of cemented carbide. Tungsten carbide is made by adding iron tungsten as raw material of tungsten in molten carbide by the carbidemaking process. It is also called high-speed carbide or tool carbide, and its tungsten content is generally 15-25%.

 

The wear resistance of cemented carbide is determined by its grain size and cobalt content. The finer the grain size and the lower the cobalt content, the higher the hardness. On the contrary, the lower the hardness. It should be mentioned that the choice of resistance Grinding cemented carbide should not only look at the hardness, but depends on the requirements of its use. Generally, the cemented carbide for cutting is recommended to be made of YW2, which has a relatively high hardness, but if the working conditions are more frequent, the toughness must be considered. , But the toughness and the hardness itself are in conflict with each other. In this case, you can consider choosing a YG-type fine-grained alloy.

 

As for which cemented carbide is the most wear-resistant, in fact, it mainly depends on the conditions of use. The most wear-resistant cemented carbide material may be more brittle, so it may not be usable. Under the same conditions, generally speaking, the smaller the particles of tungsten carbide, the higher the hardness, and the more wear-resistant it is. If there are several materials to choose from, such as domestic materials: YG3>YG6>YG
